Difference between ANSYS and ANSYS LS DYNA
Difference between ANSYS and ANSYS LS DYNA
(OP)
Hi,
Can anyone tell me what the difference is between using ANSYS static non-linear analysis and ANSYS LSDYNA? Is LSDYNA for extremely large deformations? and how would you recognize how much deformation ANSYS non-linear can handle?

RE: Difference between ANSYS and ANSYS LS DYNA
You didn't say which version of Ansys you are using. There is an implicit and explicit version oth of which work via a stiffness matrix approach. They aren't much use for short duration events as the timestep become extremely small and the run times very long to get good results.
Horses for courses.
