Hello

How is it possible to create a dynamic zone in 2D tri mesh (or quad) that when the wall (or interior) is moving the mesh at the boundaries adds more nodes rather than it just "absorbs" the movement ?

rigid body, allows to specify the motion of the zone but it means it does not touch the initial mesh

deformingr emeshes the mesh but again keeps the same number of nodes so you potentially end up with very skewed cells near a moving boundary.
