This record causes remeshing if switch is set to -yes.
Nodes are replaced either such that the mesh becomes more regular (geometric remeshing) or such that the mesh becomes more dense in areas of residues (residue remeshing).
By example, the geometric remeshing can be used after local mesh refinement (control_mesh_refine_locally). And by example, the residue remeshing can be used so that nodes follow wave propagation phenomena.
The remeshing can only be applied in combination with time steps, so a control_timestep record with the same index should be present.
See also control_mesh_remesh_factor and node_boundary.
