Member Function Documentation

void itk::fem::Solver::ApplyBC	(	int	dim = `0`,
		unsigned int	matrix = `0`
	)

inherited

Apply the boundary conditions to the system.

Note: This function must be called after AssembleK().

Parameters

matrix	Index of a matrix, to which the BCs should be applied (master stiffness matrix). Normally this is zero, but in derived classes many matrices may be used and this index must be specified.
dim	This is a parameter that can be passed to the function and is normally used with isotropic elements to specify the dimension in which the DOF is fixed.

Apply the boundary conditions to the system.

Store a temporary pointer to load object for later, so that we don't have to access it via the iterator

Apply boundary conditions in form of MFC loads.

We add the multi freedom constraints contribution to the master stiffness matrix using the lagrange multipliers. Basically we only change the last couple of rows and columns in K.

Apply essential boundary conditions

void itk::fem::SolverHyperbolic::AssembleElementMatrix ( Element::Pointer e )

virtual

When assembling the element matrix into master matrix, we need to assemble the mass matrix too.

Here we finaly update the corresponding element in the master stiffness matrix. We first check if element in Ke is zero, to prevent zeros from being allocated in sparse matrix.

Reimplemented from itk::fem::Solver.

void itk::fem::Solver::AssembleF ( int dim = 0 )

inherited

Assemble the master force vector.

Parameters

dim	This is a parameter that can be passed to the function and is normally used with isotropic elements to specify the dimension for which the master force vector should be assembled.

Assemble the master force vector

Convert the external loads to the nodal loads and add them to the master force vector F.

Store a temporary pointer to load object for later, so that we don't have to access it via the iterator

Pass the vector to the solution to the Load object.

Here we only handle Nodal loads

If using the extra dim parameter, we can apply the force to different isotropic dimension.

FIXME: We assume that the implementation of force vector inside the LoadNode class is correct for given number of dimensions

Element loads...

If array of element pointers is not empty, we apply the load to all elements in that array

If the list of element pointers in load object is empty, we apply the load to all elements in a system.

Handle boundary conditions in form of MFC loads are handled next.

Handle essential boundary conditions.

If we got here, we were unable to handle that class of Load object. We do nothing...

Adjust the master force vector for essential boundary conditions as required.

void itk::fem::Solver::AssembleK ( void )

inherited

Assemble the master stiffness matrix (also apply the MFCs to K)

Before we can start the assembly procedure, we need to know, how many boundary conditions if form of MFCs are there in a system.

Now we can assemble the master stiffness matrix from element stiffness matrices.

Since we're using the Lagrange multiplier method to apply the MFC, each constraint adds a new global DOF.

Step over all elements

Step over all the loads again to add the landmark contributions to the appropriate place in the stiffness matrix

void itk::fem::Solver::AssembleLandmarkContribution	(	Element::Pointer	e,
		float	eta
	)

virtualinherited

Add the contribution of the landmark-containing elements to the correct position in the master stiffess matrix. Since more complex Solver classes may need to assemble many matrices and may also do some funky stuff to them, this function is virtual and can be overriden in a derived solver class.

Here we finaly update the corresponding element in the master stiffness matrix. We first check if element in Le is zero, to prevent zeros from being allocated in sparse matrix.

bb1	Lower limit of a bounding box of a grid.
bb2	Upper limit of a bounding box of a grid.

inherited

Sets the LinearSystemWrapper object that will be used when solving the master equation. If this function is not called, a default VNL linear system representation will be used (class LinearSystemWrapperVNL).

Parameters

ls	Pointer to an object of class which is derived from LinearSystemWrapper.

Note: Once the LinearSystemWrapper object is changed, it is used until the member function SetLinearSystemWrapper is called again. Since LinearSystemWrapper object was created outside the Solver class, it should also be destroyed outside. Solver class will not destroy it when the Solver object is destroyed.

Change the LinearSystemWrapper object used to solve system of equations.

Since the itk::Image is templated over the number of dimensions, we have to know this at compile time. Solver class, however, can handle elements in any number of dimensions. In order to be able to use the Image, we choose the maximum number of space dimension that this function will be able to handle. Any unused dimensions are filled with zero.

For example: If a 2D node coordinates are {1.0,3.0} then the corresponding phisycal point in an image is {1.0,3.0,0.0};
