LinearSOESolver

DomainSolver is an abstract class. DomainSolver objects are responsible for performing the numerical operations required for the domain decomposition methods.

// Constructor

// Destructor

// Public Methods

classTag is needed by the LinearSOESolver objects constructor.

Causes the condenser to form \(A_{ee}^* = A_{ee} -A_{ei} A_{ii}^{-1} A_{ie}\), where \(A_{ii}\) is the first numInt rows of the \(A\) matrix. The original \(A\) is changed as a result. \(A_{ee}^*\) is to be stored in \(A_{ee}\).

virtual int condenseRHS(int numInt) =0;

Causes the condenser to form \(B_e^* = B_e - A_{ei} A_{ii}^{-1} B_i\), where \(A_{ii}\) is the first numInt rows of \(A\). The original \(B\) is changed as a result. \(B_e^*\) is to be stored in \(B_e\).

virtual int computeCondensedMatVect(Vector &u, int numInt) =0;

Causes the condenser to form \(A_{ee} u\).

virtual Matrix &getCondensedA(void) =0;

Returns the contents of \(A_{ee}\) as a matrix.

virtual Vector &getCondensedRHS(void) =0;

Returns the contents of \(B_e\) as a Vector.

virtual Vector &getCondensedMatVect(void) =0;

Returns the contents of the last call to computeCondensedMatVect(). virtual int setComputedXext(const Vector &u) =0; Sets the computed value of the unknowns in \(X_e\) corresponding to the external equations to u. The number of external equations is given by the size of vector \(u\).

virtual int solveXint(void) =0;

To compute the internal equation numbers \(X_i\) given the value set for the external equations in the last call to setComputedXext().
