The solvers can generate adapted meshes for several problem types. See Adaptation and Error Estimates and The Adaptive Mesh Refinement Solver.

The meshes generated by the stationary or eigenvalue adaptive solver are based on the original meshing sequence and can be modified. The settings window for such a meshing sequence shows a reference to the generating study in the Adaptation study list. Click the Go to Source button () to move to that generating study. Click the Disconnect from Study and Edit button, or right-click the Mesh node and select Disconnect from Study and Edit, to unlock the sequence and enable editing. Note that unlocking the sequence disconnects the mesh from the study that generated it; if you run the study again, this mesh is ignored and a new meshing sequence is generated. However, you can manually select this meshing sequence in the mesh selection of a study step, to run the study on the adapted and modified mesh.
