Hello,<\/p>\n

I am trying to model a wave tank in LS-DYNA using the Structured ALE (S-ALE) method. So far my model consists of the structured ALE mesh, half composed of water and half composed of air, and a rigid piston composed of shell elements with a prescribed motion. The model runs fine up until I add the keyword ALE_STRUCTURED_FSI, which gives the following errors (taken directly from LS-RUN):<\/p>\n

For reference, here is line 128 of my file (with added spaces for clarity):<\/p>\n

In the above, lstrsid = 4 = Rigid Piston, alesid = 1 = S-ALE mesh, mcoup = -102 = AMMG for water only (not air).<\/p>\n

Can anyone explain why I am getting this error, and how to fix it? Any help will be GREATLY appreciated.
