I’m trying to implement both mesh conforming and non-conforming Level-set methods in NGSolve.
Is there already a fast marching algorithm (or a convenient data-structure) in NGSolve I can use/access to compute the signed distance to compute an implicit boundary ?
I’m having trouble understanding the effect .SetDeformation/UnsetDeformation command on the mesh. Do the BilinearForm have to be redefined or just reassembled ? Is the quality of the mesh is somewhat preserved by this command ?
