Detailed Description

The base class for all recovery models, which perform nodal averaging or projection processes for internal variables typically stored in integration points.

The recovery can be performed on one region. Region is defined by given set containing elements defing the region volume. The element set can be set up in the input file, or created dynamically. If Averaging over multiple regions is needed, multiple instances of nodal recovery model should be created, o single instance reused.
