Iteration number limit... Iteration stops when this limit is reached and load step is finished
regardless of other criteria.

if the analysis dont converge very well. it deppend on this iteration number limit, how many iteration will be calculated to get good results.

for 40 iteration can be the error much smaller then for 20, but it takes more time..

Plz i would to know the meaning of iterations or the simplified meaning for example

What is the difference between making the solution parameter 40 iteration & making it 20 iteration
Does this changes anything ???

Thank you
