DMAdaptorMonitorErrorDrawLG

Plots the error norm at each iteration of an adaptive loop.

Synopsis

#include "petscdmadaptor.h" 
PetscErrorCode DMAdaptorMonitorErrorDrawLG(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, obtained via DMAdaptorMonitorErrorDrawLGCreate()

Options Database Key

• -adaptor_error draw::draw_lg - Activates DMAdaptorMonitorErrorDrawLG()

Notes

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.

Call DMAdaptorMonitorErrorDrawLGCreate() to create the context needed for this monitor
