Reply To: Time Step Ansys LS-DYNA

[Killian HOLLEBEKE]

Exact. I want to reproduce a model made with a Fortran code on ANSYS LS-DYNA and that's what the author said in the description of his model:

"In addition the high value of rupture speeds and the relative small dimensions of the model require a quite small integration time step and large computational efforts to identify changes in the propagating wave field."* The author have set a time step dt = 0,338e-8 s.
