quality of results (conversion)
 

How can i judge after a solver run if the results are allready converted
using the .lsf and the .out file???
what kind of creterias should be present so i can say that the result is good enough?
thank you!

Read the documentation about convergence tolerances.

But you cannot tell from a single simulation whether your results are good enough. You need to do a series of simulations sweeping all major tunable parameters to determine the sensitivities.
