Altair Compose 2023 new features

1.Library Creator

Library Creator is a GUI utility that helps create, modify and encrypt extensions.

From the File Utilities ribbon, select Library Creator.

Library Creator has tabs for entering basic information and optional files for creating Plugin.xml, loader.oml, unload.oml and organized folders to use as extensions.

Features include:

•Create an extension from scratch by selecting Basic and/or Optional.

•Create extensions from scratch and encrypt them by selecting Basic and/or Optional.

•Load existing extensions, modify them and encrypt them.

•Load existing extensions and encrypt them.

•Encrypting python files is currently not supported.

The tool creates necessary files and folders in the following structure

2. Calling mode

Console call mode now supports plotting and visualization with the “-withgui” parameter.

compose_console.bat -withgui -continue -f BodeNyquistPlot.oml

Batch mode now supports creating and saving plots using the “-withgui” parameter. This requires a graphics card.

Compose_Batch.bat -withgui -f BodeNyquistPlot.oml

3. Create a new UI

New workflow improves ease of use.

The GUI includes the following parts:

1. File menu: contains common operations

2. Top ribbon: buttons based on uipushtool function

3. Tab: Provides switching function

4. Left table: Select signal and model

5. Canvas: Display drawing

6. Left panel: Displays data set and model information

7. Right panel: input parameters

8.File information text box

Preprocessors can be used to plot, filter signals and save data.

Generators have the following capabilities:

•Arrange parameters in tabs

•Add a form for all features in training

•Physical constraints can be selected using the drop-down menu instead of writing

The post-processor has the following functions:

• Visualize all results (loss metrics, accuracy checks, hyperplanes and time simulations) on one page with fewer clicks

•Handle multiple models without repeatedly loading models

4. Heat map

Added a heatmap to show correlations between features. This helps in selecting features based on correlation coefficients. The Correlation Coefficient slider helps get the most relevant features.

5. Automatic exploration

Auto Exploration allows you to train multiple models with different hidden layers, activation functions and neurons.

6. Stop training

To stop model training, click the Stop button

7. Create a new OML command

CAE Reader 3D*

caereder3d now supports extracting composite layers.

•The getlayername3d, getlayerindex3d, and getlayerslist3d commands extract composite layer information and model information from the CAE result file.

•The “layer” parameter in readcae3d can get the layer information from the above command and extract the results from the composite layer.

•Supports New caerederoptions command to set reader properties.

oSupported attributes: “validatetime”

 If set to “true”, it will verify that the time channel values are the same. This is the default behavior.

 If set to “false”, time channel information will not be verified and results will not be extracted using NaN when there are no results.

communicate*

The communication library provides commands that support various communication protocols.

The MQTT communication protocol is supported in Compose. The library contains the following commands:

•mqttclient: connect to MQTT interrupt

•mqttpublish: Publish topic messages to the MQTT broker

Graphics objects support new callback functions.

For the graph:

•Windowbuttondownfcn: Function triggered when a mouse button event occurs on a graphics object.

•Windowbuttonmotionfcn: Function triggered when the mouse moves within the graphics area.

•Windowbuttonupfcn: Function triggered when a mouse button release event occurs on a graphics object.

•Windowkeypressfcn: Function triggered when a key event occurs on a graphics object. This function is triggered if the shape or its sub-object has focus.

For axis and uicontrol:

•Button fcn

uitab:

•selectionchangedfcn: Function triggered when tab changes.

9. Mathematics

• Statistical functions can now ignore NaN values when evaluating:

o nanmean, nanmedian, nanstd, nansum, nanvar

o The min and max functions can now ignore NaN values when evaluating.

• Krona:

o Certain operations on the Kronecker product can be applied to a and B without computing the actual product kron(a,B).

oCronrod object allows this shortcut to be executed where possible.

oProvides efficient and easy calculation capabilities when processing large matrices.

•Gradient functions are now supported to calculate the gradient of a function or sampled data.

•histc calculates histogram counts.
