DMAdaptorAdapt#

Creates a new DM that is adapted to the problem

Synopsis#

#include "petscdmadaptor.h" 
PetscErrorCode DMAdaptorAdapt(DMAdaptor adaptor, Vec x, DMAdaptationStrategy strategy, DM *adm, Vec *ax)

Not Collective

Input Parameters#

  • adaptor - The DMAdaptor object

  • x - The global approximate solution

  • strategy - The adaptation strategy

Output Parameters#

  • adm - The adapted DM

  • ax - The adapted solution

Options database Keys#

  • -snes_adapt - initial, sequential, multigrid

  • -adapt_gradient_view - View the Clement interpolant of the solution gradient

  • -adapt_hessian_view - View the Clement interpolant of the solution Hessian

  • -adapt_metric_view - View the metric tensor for adaptive mesh refinement

Note#

The available adaptation strategies are#

  • **** -*** Adapt the initial mesh until a quality metric, e.g., a priori error bound, is satisfied

  • **** -*** Solve the problem on a series of adapted meshes until a quality metric, e.g. a posteriori error bound, is satisfied

  • **** -*** Solve the problem on a hierarchy of adapted meshes generated to satisfy a quality metric using multigrid
