control_mesh_refine_locally_minimum index minimum_length

With this record you can set the minimum length allowed for elements in a local mesh refinement.

This especially is handy to prevent elements becoming smaller than the width of localisation zones in softening analysis. In this case use the, experimentally determined, localisation zone with for minimum_length. This keeps energy dissipation over the localisation zone finite, and thus prevemts excessive mesh dependency of the results.
