RelativeTotalNormDispIncrTest

RelativeTotalNormDispIncrTest

RelativeTotalNormDispIncrTest(tol: float, max_iter: int, print_flag: int = 0, norm_type: int = 2)

Bases: Test

Relative total norm displacement increment convergence test.

RelativeTotalNormDispIncrTest checks the current norm of the displacement increment against the cumulative total displacement increment norm.

Tcl form

test RelativeTotalNormDispIncr <tol> <maxIter> <printFlag> <normType>

Example

from femora.core.model import Model

model = Model()
test = model.analysis.test.relativetotalnormdispincr(
    tol=1e-6,
    max_iter=100,
    print_flag=1,
    norm_type=2,
)

Create a RelativeTotalNormDispIncr convergence test.

Parameters:

Name	Type	Description	Default
tol	float	Tolerance criteria for convergence.	required
max_iter	int	Maximum number of iterations to perform before returning failure.	required
print_flag	int	Print control flag. 0 prints nothing, 1 prints norm info each iteration, 2 prints norms and iterations at success, 4 prints norms, displacement, and residual vectors, 5 prints warnings only.	0
norm_type	int	Mathematical norm type to use. 0 for Max-norm, 1 for 1-norm, 2 for 2-norm (default).	2
