Detailed Description

VarFormOrthoMesh

DONT EVER, HIDE THE METHOD reinit(OrthoMesh*) IN THE DERIVED CLASS. IF YOU NEED TO DO SOMETHING LIKE THAT, OVERRIDE THE METHOD mesh_change INSTEAD

virtual void VarFormOrthoMesh::assembly_local_rhs	(	OrthoMesh::Cell_It &	cell,
		VecDouble &	BL
	)			[pure virtual]

Assembly the local system right hand side not including the Neumman Condition. That is computed in another method neumann_condition()

Parameters:

	cell	The cell in the mesh to build the local system
	BL	To contain the right hand side of the local system The method assumes that the vector has already the correct size. You can get the local system rank using the dimension of the matrix returned by get_local_sparsity() method.

Implemented in VarFormPoisson.

virtual void VarFormOrthoMesh::assembly_local_system	(	OrthoMesh::Cell_It &	cell,
		Matrix &	ML
	)			[pure virtual]

Assembly the local system

Parameters:

	cell	The cell in the mesh to build the local system
	ML	Matrix to contain the local system. The method assumes that the local matrix has already the correct sizes. You can get the local system rank using the dimension of the matrix returned by get_local_sparsity() method

Returns:

The local system at parameter ML

Implemented in VarFormPoisson.

virtual const Matrix& VarFormOrthoMesh::get_local_sparsity

(

)

[pure virtual]

Get the sparsity of the local system. The sparsity is represented by a full matrix with the same size as the local system matrix. A zero entry on position (i,j) means that this position is always zero in the local system. 1 means that such entry is always different of zero.

Returns:

The sparsity pattern of the local system

Implemented in VarFormPoisson.

virtual void VarFormOrthoMesh::mesh_change

(

)

[protected, pure virtual]

Implemented in VarFormPoisson.

virtual void VarFormOrthoMesh::neumann_condition	(	VecDouble &	Bl,
		OrthoMesh::Cell_It	cell,
		OrthoMesh::Face_It	face,
		unsigned	face_dir,
		Function3D &	fN
	)			[pure virtual]

Set the RHS of the local system with the Neumman condition

Parameters:

	Bl	To contain the RHS with neumann condition This vector should be initialized with the right size
	cell	Cell of the local system
	face	Face where to get the neumman condition. The face must belong to the cell passed on the previous parameter.
	face_id	The direction of the face in respect to the cell Ex: LEFT_FACE, RIGHT_FACE, BOTTOM_FACE .....
	fN	The function that specifies the Neumman condition. The meaning of this function is specific to each variational formulation. Programmers Note: Always write a piece of documentation containing the meaning (what the value is) of the neumman function. For example FN(x) = Vel(x)*n(x), where n is the outward normal or n is the inward normal and so on.

Implemented in VarFormPoisson.

void VarFormOrthoMesh::reinit

)

[inline]

Initialize the mesh, dont ever, hide this method in the derived class, if you need to do something like that, override the method mesh_change instead

Parameters:

mesh

Returns:

      return;
    _pMesh=&mesh;
