Detailed Description

PatchIntegrationRule provides integration over a triangle patch.

Input to the constructor is: -int n: number of quadrature points per triangle. -Element *e: parent element pointer -iTriangles: array of triangles describing the subdivision of the element.

Member Function Documentation

virtual const char* oofem::PatchIntegrationRule::giveClassName ( ) const

inlinevirtual

Reimplemented from oofem::GaussIntegrationRule.

Definition at line 72 of file patchintegrationrule.h.

contextIOResultType oofem::PatchIntegrationRule::restoreContext	(	DataStream &	stream,
		ContextMode	mode,
		void *	obj
	)

virtual

Restores receiver's context to stream.

Calls restoreContext service for all receiver's integration points. Note: does not call the FEMComponent::restoreContext service, in order not to write class id info for each integration rule.

Parameters

stream	Input stream.
mode	Determines amount of info available in stream (state, definition, ...).
obj	Should be a pointer to invoking element, ie., to which the receiver will belong to.

Exceptions

ContextIOERR If error encountered.

contextIOResultType oofem::PatchIntegrationRule::saveContext	(	DataStream &	stream,

	)

virtual

Saves receiver's context to stream.

Calls saveContext service for all receiver's integration points. Note: does not call the FEMComponent::saveContext service, in order not to write class id info for each integration rule.
