Different scope result for two different run times

Question

1 个投票

Here are two scopes of the same simulation run for different run times 50s and 100s. For 50 s, the concerned parameter remains constant but not in case of 100s, it starts changing after ~17 s, but in negligible magnitude. has anyone faced the same problem, if yes, is there any explanation to it.

here are the images: 50 s: http://i.imgur.com/CKVlm9M.png

I 've faced the same problem, I was using 1/p block. But could not find the explanation.

The only logical explanation I can guess, is: if the solver's step time is set to variable, then for different stop time, the variable step time changes differently.

seems a bit long shot but its the only possible explanation.......yes the solver is set to variable......any possible solutions ????
