I did a WRC 107 analysis of a nozzle connected to a shell for a client on Compress. However I received comments on my design telling me that my equipment is falling outside of the scope of WRC 107. Other packages indeed give this warning but Compress not for the same configurations. Can anyone tell me why? The beta value for my configuration is 0.652 for my equipment which falls off the graphs of WRC 107 (WRC 107 gives results for beta values up to 0.5). Can it be that Compress evaluates the stress at beta = 0.5 instead on extrapolation to 0.652? Taking values at 0.5 would seem to be more conservative.
