Set Environment Variables
The number of cores used by Radioss during the optimization
can be defined using the OptiStruct script options
-rnt
and -rnp
options.
If more advanced Radioss options need to be used, such as single precision or a specific version of Radioss, set the following environment variables.
Linux (bash):
export RADIOSS_SCRIPT=$ALTAIR_HOME/altair/scripts/radioss
export RADIOSS_ARGS=” -np 24 -nt -2 -sp -v 2019”
Windows:
set RADIOSS_SCRIPT=%ALTAIR_HOME%\hwsolvers\scripts\radioss.bat
set RADIOSS_ARGS=” -np 24 -nt -2 -sp -v 2019”
The script defined via RADIOSS_SCRIPT
will be executed by OptiStruct when the Radioss outerloop
simulation is done. The RADIOSS_ARGS
options will be used as arguments to
the RADIOSS_SCRIPT
. The RADIOSS_SCRIPT
must be a script
that runs both the Starter and the Engine.
