Hello, I am setting up a FSI simulation in LS dyna using the S-ALE solver. I would like to set up a coarse mesh for the fluid domain and refine it dynamically, near the Lagrangian structure to which the fluids are coupled(*CONSTRAINED_LAGRANGE_IN_SOLID).<\/p>\n

<\/p>\n

The sphere inside is a lagrangian structure (PID=1). I want the S-ALE mesh elements close to the sphere to be refined dynamically. <\/p>\n

I have tried the following using *CONTROL_REFINE_ALE keycard<\/p>\n

<\/p>\n

I have set up a Pressure based refinement condition with the Reference value as 0 so that all ALE solid elements that are coupled to the lagrangian sphere can be refined.<\/p>\n

MMSID=3 is a MULTI_MATERIAL_GROUP_SET containing all the MM groups in the model (Air and Water). <\/p>\n

I get the following error when including this keycard to refine the ALE mesh, whereas the solution works fine without the *CONTROL_REFINE_ALE keycard. <\/p>\n

<\/p>\n

Could someone please explain if there is a possible solution to this error or if there are mistakes in my model definition.<\/p>\n

Thanks in advance!<\/p>\n
