Hi,
I am modelling an time dependent FSI problem; wave interaction with discrete floating sheets. Laminar flow with phase field is used to model the air-water fluid domain. Multibody dynamics with FSI pair is used for the structural elements. The freely floating sheets can collide with each other, UNION ASSEMBLY is used with CONTACT PAIRS defined for the colliding boundaries. An offset from the geometric destination surface is provided for not breaking the fluid domain during collision, still the structure fails when the offset value is obtained. In the COMSOL blog it is mentioned that for unconstrained domains a spring foundation need to be provided, how to define that for the present scenario?
