Problem in I-V characteristics!

[nooneknows08]

When i run the following script it gives error exceeded max. no of iterations. Please help me find a solution

I believe if you change the  line max_steps that will fix your problem. Currently you have the max iterations at 100 and usually when i exceed the 100 steps for my systems, I have set up my geometry incorrectly.


the line is under iteration control parameters in the vnl

and it look like this in your script.py file

iteration_control_parameters = iterationControlParameters(
    tolerance = 1e-005,
    criterion = IterationControl.TotalEnergy,
    max_steps = 100
)

This system will never converge as the geometry makes no sense at all.
