Synopsis

#include "petscdmadaptor.h" 
PetscErrorCode DMAdaptorMonitorErrorDraw(DMAdaptor adaptor, PetscInt n, DM odm, DM adm, PetscInt Nf, PetscReal enorms[], Vec error, PetscViewerAndFormat *vf)

Collective

Input Parameters

• adaptor - the DMAdaptor

• n - iteration number

• odm - the original DM

• adm - the adapted DM

• Nf - number of fields

• enorms - 2-norm error values for each field (may be estimated).

• error - Vec of cellwise errors

• vf - The viewer context

Options Database Key

• -adaptor_monitor_error draw - Activates DMAdaptorMonitorErrorDraw()

Note

This is not called directly by users, rather one calls DMAdaptorMonitorSet(), with this function as an argument, to cause the monitor to be used during the adaptation loop.
