RADIOSS Automatic Chain Run

Altair Forum User

Hello,

I have several analysis and am thinking of running them automatically one after another overnight. In the RADIOSS user guide there is one topic that discuss this option, but unfortunately the given example is for linux. As i'm not so good with LINUX and WINDOWS customization, i hope some of you could help me to set the script for WINDOWS 7.

The step for LINUX is as follows:

'How to chain several runs one after each other, automatically?

Previous pageNext page Print this Topic

You can chain several runs one after each other by creating a script file with all the commands to execute; when executing the script, these commands will execute one after each other.

In case of a UNIX or LINUX system, write on the first line of a file:

#! /bin/csh

This means that this script will be read by the csh interpreter. Then write the commands for running the computations.

Below is an example of a so-called “my_script” script file.

#!/bin/csh

setenv RADFLEX_PATH $ALTAIR_HOME/hwsolvers/bin/linux32/

cd case1

s10_p4linux9 -i CASE1_0000.rad

e10_p4linux9 -i CASE1_0001.rad

e10_p4linux9 -i CASE1_0002.rad

cd case2

s10_p4linux9 -i CASE2_0000.rad

e10_p4linux9 -i CASE2_0001.rad

Then give the right for executing this file as follows:

chmod +x my_script

Finally, you can execute the script file with the command:

./my_script'

Thank you very much in advance.

If you have the latest version of the HyerWorks solvers installed, (HW11.0.220-HWSolvers) then start the solver gui and it will manage launching jobs sequentially as you want to do. On Windows you click the Radioss options from the HyperWorks menu.

On Linux you can start the GUI by using, install_directory/altair/scripts/radioss -gui

In the solver gui select the files you want to run, enter options then click Run. Do this with each file you want to run and it will run the first one and queue the next ones and run them after.

If you are unable to install the update, then I would create a *.bat file on Windows and put the commands to run the programs in there. Do an Internet search to learn more about *.bat files.

In your BAT file you would use this command to In this case, I would use this command in your BAT file to launch both the starter and the engine files for each run. The -both option runs both the starter and the engine and the -nt will use 2 processors if you have a core machine.

'C:\Program Files\Altair\11.0\hwsolvers\bin\win64\radioss.bat' -both -nt 2 c:\run1\myrun1_0000.rad

'C:\Program Files\Altair\11.0\hwsolvers\bin\win64\radioss.bat' -both -nt 2 c:\run2\myrun2_0000.rad

'C:\Program Files\Altair\11.0\hwsolvers\bin\win64\radioss.bat' -both -nt 2 c:\run2\myrun2_0000.rad

Thanks,

Andy
