1.Problem Description
Do the Stress Analysis using FEM and Fluid flow analysis using Ansys (Multi-physics flow) of a pressure vessel with given dimensions and initial thickness and find the optimized thickness with lowest acceptable factor of safety to make the design economic.

Figure 1:CAD DRAWING
2.Solution:
1. The geometry was created in Autodesk Inventor and the details can be seen in the following figure and user defined dimensions were chosen.

2. A solid was sculpted from the interior surface of the vessel to feed into Ansys as seen in following figures.

3. The sculpted solid was imported in Ansys as a .stp (step) file and meshing was done was per requirement.

4. Boundary conditions were defined and solution output and control was decided and inlet outlet values were given. INLET :- 3.5 bar and OULET: 3 bar

5. Ansys solves the problem and gives the maximum pressure to be approximately equal to 0.339 MPa.

6. This value of pressure is noted and used in inventor. In stress analysis tool of the inventor a static single point solution was selected along with other conditions and materials and pressure values were given.
