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. pause pause
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
#!/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
