Detailed Description

Field defined by values defined on unstructured grid. This implementation does not require that underlying grid is oofem mesh (composed of DofMagars and Elements), but rather simple objects (Vertices and Cells) which in turn does not have to provide complex FE services. Typically used to map extermal field to mupif. The performance is robust but quite slow due to excessive searching. For external fields, use rather DofManValueField.
