Detailed Description

Class representing a field of an internal variable smoothed from integration points into nodes.

It is relying on NodalRecoveryModel to smooth the data.

int oofem::SmoothedNodalInternalVariableField::evaluateAt	(	FloatArray &	answer,

		TimeStep *	tStep
	)

virtual

Evaluates the field at given DofManager.

This potentially can be resolved quickly, as receiver data may be described using values at dofManagers. 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.
