How do I place a Lagrange structure into an ALE element?
-

I am modelling a FSI problem and am having an issue with placing the Lagrange structure (steel H piles in this case) into the Eulerian elements (water in this case). The issue is if I model the piles directly in to ALE mesh and assign a coupling contraint between the pile elements and the water elements, it creates an instability and sends the water flying in all directions, which is definitely a non-physical behaviour. Note that this does not occur at t = 0 sec, but rather after some time has elapsed (say 0.5 to 1 seconds). Does anyone know how to correct this issue? Thank you.
