You create a submodeling study based on the static analysis of a pressure vessel. The submodeling study contains only the supporting frame of the pressure vessel model. Then you refine the solid mesh of the supporting frame and rerun the analysis to improve the accuracy of the results.

To open the model, go to install_dir\samples\whatsnew\Submodeling\pressure_vessel.sldprt.

Ready Pressure study features:
- Applies a pressure of 100 psi on the inner faces of the tank.
- Defines a distributed mass of 700 lbs (for liquefied gas) inside the tank.
- Applies a gravity load.
- Applies four mesh controls.
