In Compress we have a simple cylinder and a single LWN nozzle with user-defined nozzle loads. The output displays a nozzle design pressure of zero. The pressure stresses in the WRC 537 portion of Compress are also equal to zero.

Is anyone aware of a default value that could trigger this?

I tried adding heads on the cylinder to see if that could solve the problem but it did not.

We have Compress 2017 Build 7710.

Thanks.
 
Turns out "full area replacement" was checked by default and there was insufficient reinforcement... nozzle design pressure (or MAWP) was set to zero in the calculations.
