COMSOL 6.2 - FixedMesh

Use FixedMesh to keep the mesh fixed on edges (3D) or boundaries (2D) while remeshing the faces (3D) or domains (2D).

model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"FixedMesh");

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection();

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"FixedMesh") to keep meshes on a selection of edges (3D) or boundaries (2D) fixed for the feature <ftag1> that can be any of the types RemeshFaces or RemeshDomains, respectively.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection() to specify the edge (3D) or boundary (2D) selection.
