MatFDColoringSetFrequency
Sets the frequency for computing new Jacobian matrices.
Synopsis
int MatFDColoringSetFrequency(MatFDColoring matfd,int freq)
Collective on
MatFDColoring
Input Parameters
coloring | - the coloring context
|
freq | - frequency (default is 1)
|
Notes
Using a modified Newton strategy, where the Jacobian remains fixed for
severaliterations, can be cost effective in terms of overall nonlinear
solutionefficiency. This parameter indicates that a new Jacobian will be computed
every<freq> nonlinear iterations.
