Detailed Description

Class representing field defined by nodal values associated to given domain.

Field represent the spatial distribution of certain variable. The implementation allows to set individual dofMan values; However, in the current implementation doe not allow to specify values for different time steps.

virtual

Evaluates the field at given DofManager.

This potentially can be resolved quickly, as receiver data may be described using values at dof managers. Here an additional issue exists: one needs to make sure, that passed dman is from the same domain, so that its number can be used to perform suggested quick evaluation.

If this is not the case (the field is described differently), the response can be evaluated using dofman coordinates in a standard way.
