As I'm becoming more and more acquainted with LS-DYNA's ALE implementation, I noticed in the Keyword Manual Vol I, CONTROL_ALE description that the smoothing algorithms are not supported by MPP versions. So, if I run a multi-material ALE simulation on my HPC, am I effectivley only doing an Eulerian simulation since the rezoning is not being supported? Can someone help clarify if I am correct in this assumption?

Hello Peter,

I asked our ALE expert internally, and I quote: "What should be called ALE and what should be called Eulerian is a matter of some debate in LS-DYNA circles ... What is certain is that MPP only supports AFAC=-1 in *CONTROL_ALE while SMP supports the smoothing schemes. ALE is extremely poorly parallelised in SMP, though."

We hope this helps. Please let us know if you need further clarification.

Regards,

Nanda.

Hello Peter,

Just wanted to follow up on this. I checked with our ALE developer, and he conveyed that your assumption is correct. Hope this helps.
