implicitly by the coordinates of the corner vertices of the cell: as an affine map for simplicial elements, or

as a multilinear map for tensor-product elements

. cell - the cell whose map is used.

. numPoints - the number of points to locate

2894

- realCoords - (numPoints x coordinate dimension) array of coordinates (see DMGetCoordinateDim())

Not collective

2971

2972

Input Parameters:

2973

+ dm - The mesh, with coordinate maps defined either by a PetscDS for the coordinate DM (see DMGetCoordinateDM()) or

2974

implicitly by the coordinates of the corner vertices of the cell: as an affine map for simplicial elements, or

2975

as a multilinear map for tensor-product elements

2976

. cell - the cell whose map is used.

2977

. numPoints - the number of points to locate

2978

+ refCoords - (numPoints x dimension) array of reference coordinates (see DMGetDimension())

2979

2980

Output Parameters:

2981

. realCoords - (numPoints x coordinate dimension) array of coordinates (see DMGetCoordinateDim())
