Reply To: How to decrease the run time for an SPH analysis in LS-DYNA.

[Ram Gopisetti]

do you know Form 12 of SPH works only with the MPP runs ( MSMPI , Intel MPI, PMPI)? and said to have significant computational cost in solving the model.
What is your end time of your tensile test ?
you can use form 7,8 as an alternative to avoid tensile instability (for solids like materials).
