Hello Aaron, This is kind of a dumb way, but taking your question literally, I made two separate mesh files, refining just one and then merged them with these geo commands:
Merge "mesh1.msh"; Merge "mesh2.msh"; This method however discards the geometry. The weird part is at the boundary between the two; what should happen there for flow simulations, etc? [image: image.png] Personally, for a real problem I would either increase the transfinite resolution on the lines I wanted to be more refined or add a size field (area with a different mesh refinement). The documentation has more information on these options. Perhaps using mesh partitions could work as well? I'm not really sure what those are to be honest but it sounds like similar idea.
