template<int dimworld, typename T = double>
Set surface direction functions.
The matching of the geometries offers the possibility to specify a function for the exact evaluation of domain surface normals. If no such function is specified (default) normals are interpolated.
- Parameters
-
value | the new function (or NULL to unset the function) |
