The following steps cover the simplest way to download, install and run OpenRadioss from pre-compiled binaries with scripts form command line/terminal

There are also gui tools for job submission in windows or linux available: see Python/tk guis for job submission

How to download and install OpenRadioss

to download the latest pre-compiled OpenRadioss binaries: (download to /home/user)

visit github in browser and download the binaries (links to github), or you can use ‘wget’ from a terminal window (substitute ‘latest-20230102’ for latest release date)

wget https://github.com/OpenRadioss/OpenRadioss/releases/download/latest-20230102/OpenRadioss_linux64.zip

unzip the binaries

unzip OpenRadioss_linux64.zip

This will create a directory called ‘OpenRadioss’ containing the executables

Running OpenRadioss

The script below can be used to run a Radioss model (if OpenRadioss has been extracted into OpenRadioss directory in /home/user as described above)

Simple OpenRadioss Run Script

copy the script to the folder with the radioss model to run and modify it to runnable using chmod 777 runscript.sh

to use it, the syntax is ./runscript.sh jobname_0000.rad n where 'n' is the number of threads to run in SMP mode, the script sets all required environment variables and runs both the starter and engine for the model

The content of the script is shown below for reference:

export OPENRADIOSS_PATH=$HOME/OpenRadioss echo $OPENRADIOSS_PATH echo $HOME export RAD_CFG_PATH=$HOME/OpenRadioss/hm_cfg_files echo $RAD_CFG_PATH export RAD_H3D_PATH=$HOME/OpenRadioss/extlib/h3d/lib/linux64 echo $RAD_H3D_PATH export OMP_STACKSIZE=400m export LD_LIBRARY_PATH=$HOME/OpenRadioss/extlib/hm_reader/linux64/:$HOME/OpenRadioss/extlib/h3d/lib/linux64/:$LD_LIBRARY_PATH echo $LD_LIBRARY_PATH echo "**Run Starter**" myjobname=$(echo "$1" | rev | cut -c10- | rev) echo $myjobname "running in OpenRadioss" $HOME/OpenRadioss/exec/starter_linux64_gf -i $myjobname"_0000.rad" -nt $2 echo "**Run Engine**" $HOME/OpenRadioss/exec/engine_linux64_gf -i $myjobname"_0001.rad" -nt $2 echo "Done"
