Detailed Description

template<int dim, typename real, typename MeshType = dealii::parallel::distributed::Triangulation<dim>>
class PHiLiP::MeshAdaptation< dim, real, MeshType >

Contains functions for mesh adaptation. It supports residual based and goal-oriented hp-adaptation with fixed fraction coarsening and refinement.

Note
Mesh adaptation is currently implemented for steady state test cases. Tests using FlowSolver can use mesh adaptation directly by modifying the parameters file.
