Hexagon is proud to announce the release of MSC CoSim 2024.2.
This release features improved coupled analysis with Marc and scFLOW and MSC Nastran and scFLOW. MSC CoSim 2024.2 also contains usability improvements for running jobs on Linux. New command specification options are included in the graphic interface.
Key highlights of MSC CoSim 2024.2 include:
Enhancements in MSC Nastran/scFLOW coupling
Restart completed MSC Nastran/scFLOW coupled analyses. Use computational resources more efficiently by dividing complex jobs into multiple jobs for faster run times or continuing calculations for completed jobs.
Notes:
The restart feature for MSC Nastran/scFLOW coupling is available only when using the new scFLOW command specification (COSIM command).
Enhancements for Adams/Marc coupling
The cutback feature has been improved in MSC CoSim 2024.2. The “ForcedSync” option matches Adams timesteps with those in Marc.
The benefit of this new feature is an enhancement in calculation stability. This allows larger timesteps, reducing the total computational time. A reduction of up to 60-70% in computational time can be achieved with almost identical forces/displacements.
Other enhancements
The new specification scFLOW command (COSIM command) now supports the following:
- Nastran-scFLOW steady-state coupled analyses
- Iterative CoSim Marc-scFLOW coupled analyses
Notes:
- The configuration steps in CoSimPRE are the same as when using the conventional scFLOW command (COSIM_STRUCTURE command).
- The scFLOW pre/solver in Cradle CFD 2024.2 is required to use these features in scFLOW.
- The new command specification of scFLOW is available by selecting [New specification] as [Command specification for the co-simulation using MSC CoSim] in the [Environment Setting] dialogue in scFLOWpre.
- Some features, such as the 6-DOF separation and restart, are only available with the new specification scFLOW command. New functions related to scFLOW coupling will be added using the new command specification in the future
