It is possible to use LS-Run to launch LS-DYNA with a specified input file. But the LS-DYNA system available in Workbench gives you access to the pre- and post-processing capabilities of the Mechanical Application to make it easier to set up your LS-DYNA analysis.
Note: If you are running a version of the LS-DYNA solver earlier than 12.1, you may encounter an issue running LS-DYNA through Workbench on the following Linux versions if the process ID is too large: CentOS 7.9, 8.2, 8.3; Red Hat 7.9, 8.2, 8.3. Before starting Workbench on these versions of Linux, you should issue the command:
sysctl -w kernel.pid_max=32768
The following sections provide an overview on running LS-DYNA using the Workbench system.
