DMPlexRefineRegularGetAffineTransforms#

Gets the affine map from the reference cell to each subcell

Synopsis#

Input Parameters#

Output Parameters#

  • Nc - The number of subcells produced from this cell type

  • v0 - The translation of the first vertex for each subcell, an array of length \(dim * Nc\). Pass NULL to ignore.

  • J - The Jacobian for each subcell (map from reference cell to subcell), an array of length \(dim^2 * Nc\). Pass NULL to ignore.

  • invJ - The inverse Jacobian for each subcell, an array of length \(dim^2 * Nc\). Pass NULL to ignore.

Note#

Do not free these output arrays
