Nozzle-Pro and CRNs
PVE-5522, Last Updated: May 22, 2014, By: LRB
Can I Use Nozzle-Pro for a CRN submission? Quick Answer: No.
We like using Nozzle pro for the project design phase, but when CRNs are involved, we remove the results from the final calculation package. Sometimes we can get the less accurate but more familiar WRC 107/297 methods to show a pass after we are done with Nozzle-Pro. These results are what get submitted to the jurisdictions. If the Nozzle-Pro results are required for the submission package, they have to be replicated in standard Finite Element Analysis packages with the report tailored to the reviewing jurisdiction.
Caution: Some reviewers require physical testing such as strain gauging to prove an FEA. See Evolving Acceptance below.
