FEI Functions
-
LLNL_FEI_Impl(MPI_Comm comm)
-
Finite element interface constructor: this function creates an
instantiation of the HYPRE fei class
-
~LLNL_FEI_Impl()
-
Finite element interface destructor: this function destroys
the object as well as its internal memory allocations
-
int parameters(int numParams, char **paramStrings)
-
The parameter function is the single most important function
to pass solver information (which solver, which preconditioner,
tolerance, other solver parameters) to HYPRE
-
initFields
-
Each node or element variable has one or more fields
-
initElemBlock
-
The whole finite element mesh can be broken down into a number of
element blocks
-
initElem
-
This function initializes element connectivity (that is, the node
identifiers associated with the current element) given an element
block identifier and the element identifier with the element block
-
initSharedNodes
-
This function initializes the nodes that are shared between the
current processor and its neighbors
-
int initCRMult(int CRListLen, int *CRNodeList, int *CRFieldList, int *CRID)
-
This function initializes the Lagrange multiplier constraints
-
initComplete
-
This function signals to the FEI that the initialization step has
been completed
-
resetSystem
-
This function resets the global matrix to be of the same sparsity
pattern as before but with every entry set to s
-
int resetMatrix(double s)
-
This function resets the global matrix to be of the same sparsity
pattern as before but with every entry set to s
-
int resetRHSVector(double s)
-
This function resets the right hand side vector to s
-
int resetInitialGuess(double s)
-
This function resets the solution vector to s
-
loadNodeBCs
-
This function loads the nodal boundary conditions
-
int sumInElem(int elemBlockID, int elemID, int *elemConn, double **elemStiff, double *elemLoad, int elemFormat)
-
This function adds the element contribution to the global stiffness matrix
and also the element load to the right hand side vector
-
int sumInElemMatrix(int elemBlock, int elemID, int* elemConn, double **elemStiffness, int elemFormat)
-
This function differs from the sumInElem function in that the right hand
load vector is not passed
-
int sumInElemRHS(int elemBlock, int elemID, int *elemConn, double *elemLoad)
-
This function adds the element load to the right hand side vector
-
loadComplete
-
This function signals to the FEI that the loading phase has
been completed
-
int getNumBlockActNodes(int elemBlockID, int *nNodes)
-
This function returns the number of nodes given the element block
-
int getNumBlockActEqns(int elemBlockID, int *nEqns)
-
This function returns the number of unknowns given the element block
-
int getBlockNodeIDList(int elemBlockID, int numNodes, int *nodeIDList)
-
This function returns the node identifiers given the element block
-
int getBlockNodeSolution(int elemBlockID, int numNodes, int *nodeIDList, int *solnOffsets, double *solnValues)
-
This function returns the nodal solutions given the element block number
-
int loadCRMult(int CRID, int CRListLen, int *CRNodeList, int *CRFieldList, double *CRWeightList, double CRValue)
-
This function loads the Lagrange multiplier constraints
