# 19. Remeshing

The in-core remeshing capability within Sierra/SM allows for dynamic mesh adaption, refinement, and coarsening during simulations. This enables users to enhance mesh quality in regions of interest, represent complex geometries and large deformations, improve convergence rates, and reduce computational costs.

This section describes the setup and execution of in-core remeshing, including current limitations and best practices for selecting remeshing criteria for common use cases.
