Zahid,

Charge everything to the process of learning. Sometimes it could hurt. I remember two nights I was not able to sleep when I made a mistake and finally brought it out to the Proj. Mgr. At least I did not keep the problem. Anyway on your problem, I also experienced an unreasonable figure in pipe support load due to a figure so high in pipe insulation density which I punch myself in error. Sometimes when your hand is too fast you could type-in node number in 2 even 4 digets before the input page fully open that could go to pipe density field. Always check the spreadsheet as it always easy. Check if the supports are getting unreasonably high figures and maybe that is the problem.

Regards,
