| executable / flag | meaning |
| lsdyna | (without flags) single precision, shared memory parallel |
| -dp | double precision |
| -mpp -dis -np 96 | distributed memory parallel on single 96-core-node |
| -mpp -dis -machines 1st_node_name:96:2nd_node_name:96 | distributed memory parallel on multiple 96-core-nodes |
To explore other settings, we recommend the general Ansys launcher GUI (start an interactive job as described in Usage Guide, call "launcher" on compute node after loading the Ansys module). Running the (test) job from this GUI will print out your specialized terminal command. Then you can copy the resulting command/flags to your specific Slurm job script file.
To stop an interactive LS-DYNA job press CTRL+C and then "stop"+ENTER.
