)

checks wheather B = dN/dxi around node 0

void CheckNodeIndexing

(

NuTo::InterpolationType &

rIT

)

the global index (0..mNumNodesTotal) of the node is compared to the dof index (0..mNumNodes(dof)) via the local node positions

void CheckPartitionOfUnity	(	const NuTo::InterpolationType &	rIT,
		const NuTo::IntegrationTypeBase &	integrationType
	)

checks if the shape functions sum up to 1 (at all integration points)

void CheckShapeFunctionsAndNodePositions	(	NuTo::InterpolationType &	rIT,
