Provide additional storage for a specified number of values at the nodes of the FaceElement.

Note: Since this function is executed separately for each FaceElement, nodes that are common to multiple elements might be resized repeatedly. To avoid this, we only allow a single resize operation by comparing the number of values stored at each node to the number of values the node had when it was simply a member of the associated "bulk" element. There are cases where this will break! – e.g. if a node is common to two FaceElements which require additional storage for distinct quantities. Such cases need to be handled by "hand-crafted" face elements. More... | |

This is an empty function that establishes a uniform interface for all (derived) elements that involve time-derivatives. Such elements are/should be implemented in ALE form to allow mesh motions.

This function should therefore be overloaded in all derived elements that are formulated in ALE form to suppress the computation of the mesh velocities. The user disables the ALE functionality at his/her own risk! If the mesh does move after all, then the results will be wrong. Here we simply issue a warning message stating that the empty function has been called. More... | |
