MSC CoSim 2025.1 Overview

Key Release Highlights

Enhanced Adams–Marc Coupling

• Smart Time Increment Selection: The CoSim engine now considers both its internally calculated time increment (dt_new) and Marc’s estimated time increment (dt_est), using the smaller value for simulation steps.
• Benefits: Improved convergence and performance, especially for highly non-linear simulations that previously required frequent cutbacks.

Marc-scFLOW and MSC Nastran-scFLOW Coupling Improvements

• New Iteration Control Parameter: A minimum number of CoSim iteration loops can now be specified via the CoSim Condition Wizard for:
  • Iterative CoSim mode in Marc-scFLOW
  • Static CoSim mode in Nastran-scFLOW
• Benefits: Prevents premature loop termination, enhances stability for complex or non-linear systems, and simplifies setup for fluid-structure interaction problems.

Thermal Co-Simulation Enhancements (Marc-scFLOW)

• Thermal co-simulation is now supported via the new scFLOW COSIM command specification.
• Requirements: Cradle CFD 2025.1 scFLOW pre/solver.
• Note: Advanced features like 6-DOF separation and restart are only available with the new command specification.

GUI and Workflow Improvements

• New command specification options added to the graphical interface for easier setup.

Supported Solver Integrations

• Adams (Multibody Dynamics)
• Marc (Nonlinear FEA)
• MSC Nastran (Structural Analysis)
• scFLOW (Computational Fluid Dynamics)
