Problems with parametric sweep

$
0
0
I have a model that I want to investigate with differens values on at least one of the design variables. If I change the variables value manually and compute, there is no problem but if i use variable sweep i get the following error message:

Failed to find a solution.
Maximum number of Newton iterations reached.
Returned solution is not converged.
-Feature: stationary solver1(sol2/s1)
-Error: Failed to find a solution

In parametric sweep I use for example the following parameter value:
range(0.03,0.01,0.06)
so it should only be four values that i'm trying to calculate now (when testing)

When I have been searching the internet all I can find is that it might be something about tolerance but first of all I don't understand where to set the tolerance and second of all, why does it work when i change the values manually?
