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

Thank you Ram Yes, I am running Double Precision MPP Version. Thanks, I realized it has significant computational cost.
I just want the specimen to be displaced in the x direction by 12 mm so end time = Distance/Velocity = 12/ (12x.00001) = 100,000 s. This is using a strain rate of 0.00001 s-1 and gage length of 12 mm.
I tried Form 8 as well, the Total Lagrangian but same long time to solve.
Do you know how to reduce the run time?
FEA: Mass Scaling but not sure for SPH as computation takes mass of particles into consideration.
