This is not specific to ALE, this is usefull for every problem that needs to distinguish between undeformed (reference) and deformed (current) configuration. Some time ago I switched my primary variable from the node position back to the node displacement, to be able to use the (at this point homogenious only) periodic boundary conditions, so I don't use this part of the code anymore. As I still need quantities on the reference configuration (mapping jacobian), on the current configuration (shape functions, their derivations, qp positions, normals) and the mapping between undeformed and deformed configuration I currently deform each element manually and reinit the fe myself. Does anyone know a better way to do this with libmesh? Is the FEMap class of any use here?
