Can AutoPIPE Nozzle be used to model a support on an elbow?
AutoPIPE Nozzle does not have a shell type = elbow. However, AutoPIPE nozzle does have a shell type = Cylinder, where a trunnion can be modeled atop it. Suggest this as an approximation approach for an elbow with a trunnion. To get an exact answer would require modeling in a full FEA program.
