CharacteristicSetVelocityInterpolationLocal

Sets the routine used to interpolate the velocity field along a characteristic using a locally-accessible array

Synopsis

#include "petsccharacteristic.h" 
PetscErrorCode CharacteristicSetVelocityInterpolationLocal(Characteristic c, DM da, Vec v, Vec vOld, PetscInt numComponents, PetscInt components[], PetscErrorCode (*interp)(void *array, PetscReal interpIndices[], PetscInt numComponents, PetscInt components[], PetscScalar values[], PetscCtx ctx), PetscCtx ctx)

Not Collective

Input Parameters

• c - the Characteristic context

• da - the DM describing the layout of the velocity vectors

• v - the current velocity vector

• vOld - the previous-time-step velocity vector

• numComponents - the number of velocity components to interpolate

• components - the indices of the velocity components in v and vOld

• interp - the interpolation routine, called with a local array pointer rather than a Vec

• ctx - context passed to the interpolation routine

Calling sequence of interp

• array - the locally-accessible array of the velocity vector obtained from the DM

• interpIndices - the coordinates at which to interpolate

• numComponents - the number of components to interpolate

• components - the indices of the components in the array

• values - the interpolated values, one per component per point

• ctx - the application context
