Detailed Description

Utilities for region-based adaptive mesh refinement (AMR).

This file provides functions and classes that support region-based adaptive mesh refinement, where refinement is restricted to specific user-defined regions of the computational domain.

The refinement strategy within each region can be customized depending on the application. For instance, users may perform:

• uniform refinement up to a specified refinement level, or
• indicator-based refinement guided by error estimators, restricted to the selected regions.
