This command is used to construct a CTestEnergyIncr object which tests positive force convergence if one half of the inner-product of the x and b vectors (displacement increment and unbalance) in the LinearSOE object is less than the specified tolerance.
test EnergyIncr $tol $maxNumIter <$printFlag>
$tol |
convergence tolerance |
||
$maxNumIter |
maximum number of iterations that will be performed before "failure to converge" is returned |
||
$printFlag |
flag used to print information on convergence (optional) |
||
|
|
0 |
no print output (default) |
|
|
1 |
print information on each step |
|
|
2 |
print information when convergence has been achieved |
|
|
4 |
print norm, dU and dR vectors |
|
|
5 |
at convergence failure, carry on, print error message, but do not stop analysis |
The test performs the following check:
