LS-PrePost is an advanced pre and post-processor that is delivered free with LS-DYNA. The user interface is designed to be both efficient and intuitive. LS-PrePost runs on Windows, Linux, and Unix utilizing OpenGL graphics to achieve fast rendering and XY plotting. The latest builds can be downloaded from LSTC's FTP Site.
The prefered way of accessing LS-Prepost is through OnDemand's desktop application. This gives you a preconfigured enviornment with GPU acceleration enabled.
LS-PrePost is available on Oakley cluster. The versions currently available at OSC are:.
Version | Oakley |
---|---|
v3.2 | X |
v4.0 | X* |
module spider lspp
. Use module load name
to load LS-PrePost with a particular software version. For example, use module load lspp/3.2
to load LS-PrePost version 3.2 on Oakley.
Below are instructions on running LS-PrePost on Oakley through OnDemand desktop interface with GPU acceleration enabled. To run LS-PrePost with a slower X-tunneling procedure, see the specified instructions below.
module load lspp/4.0 module load virtualgl vglrun lspp4
At startup LS-PrePost displays a graphical interface for model generation and results post-processing.
The following procedure will result in a much slower and GUI interface, but may be useful if the above instructions are not working. It can be done completely from the command line, with no need for logging into OnDemand. You may need to edit your terminal settings to enabled x11 forwarding.
ssh -X username@oakley.osc.edu
qsub -I -X -l nodes=1:ppn=12 -l walltime=hh:mm:ss -A ProjectID
module load lspp/4.0 lspp4
A x11 window should pop up. If you get a error along the lines of:
Error: Unable to initialize gtk, is DISPLAY set properly?
Double check that you:
1) logged in with x11 forwarding enabled
2) have configured your x11 settings for your terminal
3) included the -X with the qsub command
4) have a x11 client running on your computer (Xming, Xorg, XQuarts, etc.).
