Detailed Description

contains the nodes, elements and interpolations for a classic finite element mesh

Remarks

Elements contain references to nodes. Thus, a copy of MeshFem is not trivially possible and only move is allowed

Member Function Documentation

void MeshFem::AllocateDofInstances	(	DofType	dofType,
		int	numInstances
	)

Adds numInstances instances of zeros to all nodes of type dofType

Parameters

dofType

dof type

InterpolationSimple & MeshFem::CreateInterpolation

(

const InterpolationSimple &

interpolation

)

adds a clone of interpolation to the mesh (prototype pattern)

Parameters

interpolation

interpolation that is cloned and added

Returns

reference to the cloned object

Group< ElementCollectionFem > MeshFem::ElementsTotal

(

)

selects all element collections

Returns

group containing all element collections

NodeSimple & MeshFem::NodeAtCoordinate	(	Eigen::VectorXd	coords,
		double	tol = 1.e-10
	)

selects a coordinate at given coords

Parameters

coords	global coordinates
tol	selection tolerance

Returns

reference to the selected node, throws, if no node is found

NodeSimple & MeshFem::NodeAtCoordinate	(	Eigen::VectorXd	coords,
		DofType	dofType,
		double	tol = 1.e-10
	)

selects a node of type dofType at given coords

Parameters

coords	global coordinates
dofType	dof type
