Hello,
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):
Beginning of keyword reader 07/24/23 19:09:09
*** Error 10450 (KEY+450)

For reference, here is line 128 of my file (with added spaces for clarity):
*ALE_STRUCTURED_FSI_TITLE

$# lstrsid alesid lstrstyp alestyp - - - mcoup
4 1 1 1 -102
$# start end pfac fric - flip
0.0 100.0 0.1 0.0 0
In the above, lstrsid = 4 = Rigid Piston, alesid = 1 = S-ALE mesh, mcoup = -102 = AMMG for water only (not air).
Can anyone explain why I am getting this error, and how to fix it? Any help will be GREATLY appreciated. Thank you!
