Adaptive meshing techniques

Definition

Adaptive meshing techniques refer to numerical methods that adjust the mesh or grid used in computational simulations based on the characteristics of the solution being modeled. This allows for finer resolution in areas with complex behavior while using coarser meshes in regions where the solution changes less dramatically, enhancing computational efficiency and accuracy.
