When analyzing nozzle loads in Compress using the FEA package the program does not reduce the nozzle MAWP as a result of these added loads. The FEA output only identifies percent of stress in terms of actual vs. allowable.

If I am performing MAWP calculations for a vessel how do I determine a nozzle MAWP when nozzle loads have been calculated in FEA? In some cases the nozzle could be the limiting components if high loads exist.

Thanks!
 
The only way is to do it by trial and error. Even if you were outside Compress, you would have to look for the MAWP by trial and error
