Introduction - Radioss with PolyUMod
Windows Computers
One easy way to run Radioss with PolyUMod using the command line is to setup a bat-file with the commands below. The bat-file first sets the variable radi to the desired version of Radioss. It then checks if there is a file with the name libraduser_win64.dll in the current directory. If there is, then it sets the environment variable RAD_USERLIB_LIBPATH to the current directory, and uses that dll-file as the PolyUMod library.
If there is no such dll-file in the current directory, then it assumes that the environment variable RAD_USERLIB_LIBPATH already exists and contains the path the PolyUMod library. Typically this environment variable should have the following value: C:\Program Files\PolymerFEM\PolyUMod_Altair\PolyUMod_Radioss. You also need to customize the bat-file so that it contains the correct rad-file (in the example it is called cylinder_shear_BB_0000.rad), and uses the desired number of processors (using the command line argument -np). Note that the PolyUMod installer attempts to set the RAD_USERLIB_LIBPATH variable for you.
@echo off
echo ### Start Run ###
rem set radi="C:\Program Files\Altair\2020\hwsolvers\scripts\radioss.bat"
set radi="C:\Program Files\Altair\2021\hwsolvers\scripts\radioss.bat"
if exist libraduser_win64.dll (
echo Found a local PolyUMod dll file.
set RAD_USERLIB_LIBPATH=%cd%
) else (
echo No PolyUMod dll file in the working directory.
echo Use the following path for the PolyUMod library:
echo %RAD_USERLIB_LIBPATH%
echo Here are the files in this directory:
dir "%RAD_USERLIB_LIBPATH%"
)
echo ### Call Radioss ###
call %radi% -np 2 cylinder_shear_BB_0000.rad
echo Done.

Linux Computers
Running Radioss with PolyUMod using the command line on a Linux computer is also very easy. The bash script below first sets the variable radi to the desired version of Radioss. It then checks if there is a PolyUMod library in the standard locations, and sets the environment variable RAD_USERLIB_LIBPATH to the proper path.
You need to customize the script file so that is using the correct rad-file (in the example it is called cylinder_shear_BB_0000.rad), and the desired number of processors (using the command line argument -np).
#!/bin/bash
set -e
#radi="/opt/altair/2020/altair/hwsolvers/scripts/radioss"
radi="/opt/altair/2021/altair/hwsolvers/scripts/radioss"
## need to set the env variable RAD_USERLIB_LIBPATH
name="libraduser_linux64.so"
DD="/opt/PolymerFEM/PolyUMod_Altair/PolyUMod"
if [ -f "$DD/$name" ]; then
export RAD_USERLIB_LIBPATH=$DD
fi
DD="/opt/PolymerFEM/PolyUMod_Altair/PolyUMod_RADIOSS"
if [ -f "$DD/$name" ]; then
export RAD_USERLIB_LIBPATH=$DD
fi
DD=$PWD
if [ -f "$DD/$name" ]; then
echo Use the PolyUMod so-file in the current directory.
export RAD_USERLIB_LIBPATH=$DD
fi
echo a=$RAD_USERLIB_LIBPATH
ls $RAD_USERLIB_LIBPATH
##
## run it
##
$radi -np 2 cylinder_shear_BB_0000.rad
