$maxiterations

The maximum of the iteration steps to get converged. If the total solving iteration step is larger than this number then the program will stop and output the unconverged results.

Example

$maxiterations
3000

This means that if the program will stop and output the results once the total iteration steps reach 3000 times.

The $maxiterations setting in GUI interface is here
Press Contact Setting and fill in the field for the Max iteration steps as needed!
