I have a question regarding the use of the nozzle option for an API 650 nozzle in Caesar II. API 650 states that their method for calculating the displacement and flexablity factors for a nozzle are based on that nozzle meeting certain requirements regarding the distance from the bottom of the tank to the CL of the nozzle. There does not seem to be a warning during input when you have exceeded this distance.

You are correct, the software won't warn you about this. I'll put this on the list of items to address for the next release.
