Detailed Description

Copy geometry-related data from one element to other.

That can be used to copy high order geometry data from coarse element to children. That is often a case when higher order geometry is defined only on coarse elements.

Note

Element have to share the same integration points, i.e. number of integration points has to be the same, and geometric location.
