Sir there is no specific error that it displays..it just gives me the same ans every time i run it with any loadcase as in changed data. I tried to see again if am doing or entering wrong arguments but I couldn't figure out. What I did was I ran a generator outage case, an increased load case and the normal standard data case (say 6 bus system), and all of them gave me the same result. Why is it not giving any difference between its answers? Will appreciate a quick response. Thank you for your time sir.
