Hii friends,

I have a little doubt.

While running an underground pipeline model this morning,I noticed that the value of allowable streeses were displayed as zero in the stress report (W+T1+P1 : Stresses combination) for a large number of nodes in series.
Then I activated the "Allowable stresse" but even then, I am faing the same problem.

Please suggest what went wrong and what remedialaction should I take??


Thanks & Regards,
