Hi Richard and all members,

I have a model successfully run and all are within allowable code stresses. I changed the insulation density field with a reduction of 20% all throughout the system. I anticipated that the result would yield lower stresses and of course lower loads on the restraint summaries. The actual result however showed failure on SUS+F1+F4. restraint summay however showed a lesser figure as I expected. What I was doing was saving my original file with a higher insulation density to a new file name. I then change the insulation density of the new file in spread sheet and run it. Is this due to load cases setup? I can send the whole load case combination if needed. So far the one I mentioned is the only one failing. Please advice.
