Hi, everyone! I want to know whether the function adpatmesh in freefem++ can adapt the specific elements based on the initial mesh fixed or not. That is to say, can AdaptMesh refine mesh cells that meet certain error requirements while keeping the original mesh unchanged? I’m looking forward to your reply. Thank you very much!
