Features
1. MAXSURF Modeler
NURB Hull Modeling
MAXSURF Modeler provides a fast, flexible, and intuitive modeling method for a variety of hulls, superstructures, and accessories. When modeling a variety of ships from yachts to engineering vessels to large ships, trimmed NURB surfaces can be used in unlimited numbers.
With the Modeler design module, shipbuilders will be able to quickly and accurately create optimized hull shapes. They can integrate, trim, and manipulate any number of NURB interfaces to create a complete model, and they can perform hydrostatic and performance analysis or detailed construction design at any time.
With Modeler, you can interact with surface shapes directly with the mouse or keyboard. You can use the mouse to drag control points to adjust values or operate a series of flattening commands. Modeler also provides the ability to automatically transform the hull shape to match the required size and hydrostatic properties.
Smooth, accurate surfaces are essential for achieving optimal ship performance and simplifying construction. Modeler provides the ability to evaluate curvature across a surface as well as along specific surface contours, such as waterlines or diagonals. Curvature displays can be automatically and interactively updated as surfaces are modified.
MAXSURF designs are stored in a common 3D file that is available to all modules for analysis, construction, and performance prediction. Changes in Modeler are automatically available when you open a design in another module. Design database files are highly compressed and ideal for emailing to designers or builders.
Modeler’s interactive graphical environment helps you quickly learn how to use the application. There are multiple windows for viewing and changing models, and tabular views of design data are provided. Additional windows allow you to examine area curves, hydrostatic calculations, and offset tables in real time.
Data exchange is a core requirement of modern design office software, and Modeler supports many industry standard formats. You can copy and paste tables of values between Modeler and Microsoft Excel to perform a variety of custom calculations and formatting. Graphical views can be copied and pasted into other applications to help create presentations and reports.
With Modeler’s unique surface trimming capabilities, you can keep the rest of the hull flat while modeling complex surface boundaries. Interactive display of surface-to-surface intersections helps you create the desired shape, even with complex configurations such as curved transoms, stepped sheer lines, and attachments or bow thrusters. Surface trimming automatically updates as surfaces are adjusted in the design. Modeler provides all the necessary modeling capabilities for hulls, attachments, and superstructures. The Modeler Advanced module can model an unlimited number of surfaces, while the Modeler module can only model a maximum of 20 surfaces.
2. MAXSURF Stability Intact and Damaged Hydrostatic and Stability
The MAXSURF Stability module provides fast, graphical, and interactive intact and damaged stability and strength calculations for all types of MAXSURF designs.
Once you create a design with Modeler, you can use the Stability Analysis module to evaluate its stability and strength characteristics. The Stability Analysis module provides a range of powerful analysis capabilities that can handle all types of stability and strength calculations. It performs accurate calculations directly from the trimmed MAXSURF NURB surface model, without the need for any offsets or batch file preparation.
All functions in the Stability module are performed in a graphical multi-window environment, consistent with all other MAXSURF modules. Data is displayed both graphically and in tabular form, automatically updating when changes occur and as the analysis progresses. The integrated load case editor makes it easy and accurate to set up any number of loading conditions. In addition, the ability to copy and paste data directly from and to a spreadsheet makes it very convenient to prepare complex loading cases in other programs and then run them in Stability. Load cases can also be saved and reused in other design configurations.
Tank and compartment simulation capabilities are also integrated into the Stability module, allowing you to quickly and easily define the tank and compartment layout of your vessel. For more complex compartments, surfaces created in MAXSURF Modeler can be used. Tanks are automatically included as parametric objects in the weight program tables, and these parametric objects are automatically updated as the hull shape changes as the design progresses.
The tank calibration option provides detailed capacity and CG characteristics for all tanks.
The Stability module includes intact and damaged analysis method options such as hydrostatic, high angle stability, balance analysis, KN table, cross curve, limited KG and longitudinal strength analysis. For each analysis method, Stability automatically highlights the required data to be entered and provides data entry dialog boxes to ensure that the data is entered correctly.
Stability provides common standards to ensure compliance with classification society requirements. The application also allows you to develop customized standards for your own special requirements.
When the analysis is completed, all results are presented in table or graphical form. You can click on any of the graphics and move the cursor to get the exact value at any position. You can also choose how to display the table, which columns are visible, and sort the results by any column.
The automatically formatted on-screen report window accumulates the analysis results to form a ship stability manual. The application automatically inserts descriptions, tables, graphs, and charts, which you can reformat or delete at any time. You can also enter comments in the report, and cut and paste graphs from the Stability module, other MAXSURF modules, or any other application. The entire report can be generated entirely using a Microsoft Word template document.
The analysis, data entry, and data display options in the Stability module are essential features for designers of all types of vessels. For designers with limited budgets, the basic Stability module only includes full hydrostatic and high angle stability analysis methods. Stability Advanced adds tank definition and calibration, stability criteria, damage stability, longitudinal strength, limited KG, floodable length, and MARPOL oil spill analysis; Stability Enterprise adds probability-based damage stability analysis.
3. MAXSURF Motions Ship Motion Prediction
The MAXSURF Motions hydrodynamic and seaworthiness analysis module provides fast and reliable ship response and seaworthiness calculations for many designs created in MAXSURF Modeler for various sea conditions.
Using the Motions module, designers can quickly predict the seaworthiness of MAXSURF designs. The application can read the hull geometry required for analysis directly from the trimmed MAXSURF NURB surface model, without the need to prepare additional input or offset files.
The data is displayed in both graphical and tabular form and will automatically update when changes occur and as the analysis progresses. The data can be copied to spreadsheets and other applications for presentation or further analysis, such as calculating the probability of slamming and propeller water discharge, etc.
In the Motions module, you can specify the wave spectrum, heading, speed, and several other analysis parameters. Calculate the response amplitude operator (RAO) of the ship in the specified sea spectrum as well as the added resistance, important absolute and relative motions, speed, and acceleration. The motions, velocities, accelerations and seasickness (MSI) of the vessel at any position can also be calculated.
Both the slice theory and the 3D radiation diffraction panel method are available, but the panel method requires the Motions Advanced module. The slice theory is used for the heave, pitch and roll response of vessels with aspect ratios greater than 4. The panel method can be used for any hull shape, providing the response calculation in all six degrees of freedom.
The Motions Advanced module has been validated using a variety of data from various independent sources, including model tests, full ship tests and other numerical methods.
4. MAXSURF Resistance and Power Prediction
The MAXSURF Resistance module can estimate the resistance and power requirements of any MAXSURF design using industry-standard prediction techniques. It can also calculate the resistance and wave-making of slender ships using an integrated potential flow solver.
When designing a ship using MAXSURF, the calculation methods of the Resistance module can help you estimate the resistance and power requirements of the hull.
The MAXSURF Resistance module includes a number of industry-standard algorithms, and you can choose the method that best suits the hull shape you are designing.
Specific calculation methods are: Savitsky pre-displacement and displacement, Lahtiharju for displacement ships, Blount & Fox for displacement ships, Holtrop and Compton for rapid hull displacement, Fung and Series 60 for ships, van Oortmerssen for entire hull shapes (such as tugboats and fishing boats), and Delft Systemized Yacht Series for sailboats. The resistance of a MAXSURF hull can also be analyzed directly using the slender body method (using the potential flow method).
The Resistance module can automatically read any MAXSURF file and measure the required input parameters. You can override these automatically calculated values to fine-tune the calculation results to ensure that they meet your requirements.
The output of the Resistance module is provided in both tabular and graphical formats, and it is automatically recalculated when the input parameters are changed.
5. MAXSURF Structure Structural Definition and Plate Development
The MAXSURF Structure module provides initial definitions for each structural part in all types of MAXSURF designs, including hull plates, longitudinal girders, transverse strong frames, decks and longitudinal members.
Using the Structure module, the location of each structural part on the ship can be defined, and the geometry can be generated. The definition can be transferred to other CAD systems for further detailed design. Using the interactive graphics capabilities of the application, parts can be defined parametrically directly from the MAXSURF NURB surface model.
The parametric parts of the Structure module not only directly match the hull surface, but also automatically adapt to any changes that occur in the hull definition. This approach facilitates concurrent engineering, enabling design, analysis, and construction detailing to be performed simultaneously. This increases the scope for weight optimization, saving time in the detailing process.
All parts you define and calculate are stored in the integrated part list in the Structure module. Quantities, areas, weights, centers of gravity, and cut lengths are calculated and tabulated. The part list database can be sorted by any criteria, and individual parts can be renamed according to your part naming conventions. All parts can be exported to a spreadsheet or database.
The Structure module provides comprehensive functionality for arranging stringers, or longitudinal members, on the hull surface. Stringers can be automatically aligned to specific contours, set to specified perimeter intervals, or repeated in groups on the hull. Perimeter location and stringer handling work equally well in monohull or multihull vessels.
The part window provides plate unfolding methods and displays plate forming information. Perimeter differences, color plots of stresses within the plate, and the location of frames and stringers can all be displayed on the unfolded plate.
You can use the section creation, definition, and display options within the Structure module to complete the preliminary layout of the structure and plating. From the initial point-and-click section definition to the 3D shaded view of the entire structural model, the Structure module provides everything you need to quickly and accurately develop the main structure of the ship. The Structure module includes plate unfolding capabilities. Structure Advanced adds girder, frame, and deck generation capabilities.
6. MAXSURF Multiframe structural analysis and design
MAXSURF Multiframe can help structural experts determine the stresses in the ship to ensure compliance with classification society requirements and achieve strength and weight optimization.
When designing steel or aluminum structural ships, there are a variety of structural analysis methods that can be used to evaluate the structural bearing capacity of the ship and ensure compliance with classification society requirements. Multiframe is a general system based on plate beam elements that allows you to quickly model and analyze ship structures and perform static or dynamic structural behavior analysis. Multiframe is a good complement to the more time-consuming full finite element analysis and less accurate spreadsheet calculation methods.
With Multiframe, you can open geometry files from MAXSURF Structure or most other structural modeling systems and apply structural properties such as constraints, materials, and section shapes. You can create a series of load cases, then perform static or dynamic analysis and view displayed results for forces, stresses, and deflections. Dynamic results include natural frequencies and mode shapes, or more detailed time history results for time-varying loads.
Multiframe’s Excel-compatible automation interface enables customized calculations to optimize structural behavior, and provides built-in search, sort, and inspection capabilities. Automation is particularly useful for post-processing of analysis data, as well as pre-processing such as hydrostatic or wave load generation.
Multiframe makes it easy to manage the complex geometry that results from detailed structural analysis models. Clipping, searching, and sorting capabilities can be combined with rendering and animation. This allows you to easily narrow your focus to critical areas.
Multiframe also includes a shape editor, section property calculator, and a comprehensive library of common structural shapes.
7. MAXSURF Utilities MAXSURF VPP
Utilities – Sailboat Speed Performance Prediction
The MAXSURF VPP utility provides a sailing performance analysis of a yacht under various sailing conditions and generates polar curves of performance to show the predicted speed.
Sailboat designers using MAXSURF can use VPP to predict the performance of their designs under various sailing conditions.
VPP uses a similar calculation method to the original IMS Speed Performance Prediction program, solving equations for raising and lowering the hull and rig to find the equilibrium speed and optimum heel angle. VPP calculations are performed over a variety of real wind directions and speeds and are calculated by moving the jib up and down.
Integrated into VPP is a hull evaluation feature that automatically evaluates the MAXSURF design to extract the required input measurements and parameters. In addition, a small number of key values can be entered directly from IMS certificates.
The wind force and wind direction output results of VPP are provided in both tabular and graphical formats. Results include representation of wind force, hull speed, Vmg, heel angle and the various heave and drag forces involved. A set of generated polar performance curves can be selected to find critical values for any setting.
