Quickly Setup Altair Radioss™ to use PolyUMod

Setting up Radioss™ to use the PolyUMod© library is easy. Just use the following 5 steps.

1. Install PolyUMod

Follow these instructions to install PolyUMod on a Windows or Linux computer.

2. Set the environment variable "RAD_USERLIB_LIBPATH"

On Windows computers the environment variable “RAD_USERLIB_LIBPATH” should be set to one of the following:
  • C:\Program Files\PolymerFEM\PolyUMod\PolyUMod_Radioss
  • C:\Program Files\PolymerFEM\PolyUMod\PolyUMod
Check on your computer which of these directories that you have, and then set the environment variable to that path. On Linux computers set the environment variable “RAD_USERLIB_LIBPATH” to one of the following:
  • /opt/PolymerFEM/PolyUMod_Altair/PolyUMod_Radioss
  • /opt/PolymerFEM/PolyUMod_Altair/PolyUMod
Check on your computer which of these directories that you have, and set the environment variable to that path.

3. Use MCalibration to calibrate and then export a material model to Radioss format

You can learn more about MCalibration here, and take our free training course here.

4. Setup the FE Model using Altair HyperMesh™

Setup /PROP/SOLID to use full integration point elements Isolid=17
Setup /PROP/SOLID to use large strain Lagrangian strains: Ismstr=10
Specify the PolyUMod material model using /MAT/USER01

5. Run your Radioss FE simulation!

That’s it!
