hi rizkanadhira

i think you use transient time domain solver

1.first try to use frequency domain solver . its more accurate
2.second,if you have problem yet i think it rely to your history list
examine the history option tools and update and execute once and compare the errors
then contact me..
3.if doesnt match try 2013 , in some cases 2013 is better
