What is happening with octahedral stress in the version 5.2 and 5.3. I need to perform some calculation according PD 8010-2 and NEN 3650 and I can't check in Caesar the stress. Even if I choose yield stress criteria Von Misses , in the results I still have the 3D max intensity instead octahedral stress.

Is something wrong with this configuration version or Coade remove the posibility to check octahedral stress direct.

You should be getting the Octahedral stress regardless of how the switch is set in configure/setup. This is because PD 8010-2 only allows you to use the octahedral stress. Perhaps we should label the 3D Max Intensity column differently when PD8010-2 is selected, but what should we call it when you have multiple piping codes in the same file? If you perform a hand calculation to PD 8010-2 it should match the value in the 3D Max Intensity column.
