Detailed Description

Class representing Lobatto-quadrature integration rule.

The number of integration points and their coordinates and integration weights depends on integration rule type (rule for integration in 1d, 2d, 3d) and required accuracy.

int oofem::LobattoIntegrationRule::getRequiredNumberOfIntegrationPoints	(	integrationDomain	dType,
		int	approxOrder
	)

virtual

Abstract service.

Returns required number of integration points to exactly integrate polynomial of order approxOrder on given domain. When approxOrder is too large and is not supported by implementation method returns -1. Must be overloaded by derived classes.
