Hello community!
My 2D model consists of two components and two different physics . The first component is "Solid Mechanics" and the second "Laminar Flow".
Unfortunately, "Fluid Solid Interaction" physics (part of MEMS Toolbox) does not support contact between solids and fluid-solid-interaction at the same boundary, so I would like to implement it by hand.
Is it possible to apply the displacement / velocity of the solid to the boundary of the fluid and provide the stresses (pressure and shear stress) back to the solid?
How can I introduce a moving mesh (ALE) for both components/physics?
Are there some tutorials on that topic available?
Many thanks in advance
Alexander

Hello Alexander,
The moving mesh interfaces do not support topological changes, but this blog entry presents an alternative:
