Detailed Description

Specifies a tolerance for the norm of the unbalanced load vector on each iteration.

A CTestNormUnbalance object is an object which can be used in an algorithmic class to test if convergence has been achieved. The CTestNormUnbalance class tests using the norm of the right hand side Vector of a LinearSOE object and a user specified tolerance value.

Constructor & Destructor Documentation

◆ CTestNormUnbalance() [1/2]

XC::CTestNormUnbalance::CTestNormUnbalance ( CommandEntity owr = nullptr)

Default constructor.

Parameters
owrobject that owns this one.

◆ CTestNormUnbalance() [2/2]

XC::CTestNormUnbalance::CTestNormUnbalance ( CommandEntity owr,
double  theTol,
int  maxIter,
int  printFlag,
int  normType = 2 
)

Constructor.

Parameters
owrobject that owns this one.
theTolthe tolerance used in test().
maxIterthe max number of iterations to be performed.
printFlagwhat, if anything, is printed on each test.
normTypetype of norm to use (1-norm, 2-norm, p-norm, max-norm).

Member Function Documentation

◆ test()

int XC::CTestNormUnbalance::test ( void  )
virtual

Test convergence.

Returns {currentNumIter} if if the two norm of the LinearSOE objects B Vector is less than the tolerance tol. If no LinearSOE has been set \(-2\) is returned. If the currentNumIter \(>=\) {maxNumIter} an error message is printed and \(-2\) is returned. If none of these conditions is met, the currentnumIter is incremented and \(-1\) is returned. If the print flag is \(0\) nothing is printed to cerr during the method, if \(1\) the current iteration and norm are printed to cerr, and if \(2\) the norm and number of iterations to convergence are printed to cerr.

Implements XC::ConvergenceTest.
