tem_subres_prop_load Subroutine

public subroutine tem_subres_prop_load(me, tree, coloring)

Load the subresolution property from disk.

Before this can be done, the coloring information has to have been loaded.

Arguments

Type IntentOptional Attributes Name
type(tem_subres_prop_type), intent(out) :: me

Color definitions to load.
type(treelmesh_type), intent(in) :: tree

Tree to build the polynomial subresolution information for
type(tem_color_prop_type), intent(in) :: coloring

Information on the colors in the mesh.
