Pressure vessel design using ANSYS software as per ASME

The design and verification of pressure vessels are regulated by the design requirements outlined in the ASME Boiler and Pressure Vessel Code (BPVC). Designing a convention that meets the standards of the ASME BPVC code would result in a design that is characterized by a cautious approach. The present scenario may be effectively addressed via the use of contemporary finite element analysis (FEA) commercial software packages such as ANSYS. This training session will focus on the discussion of size optimization for pressure vessels that adhere to the design-by-analysis standards outlined in the ASME Sec. VIII Division 2 specification. The integration of ANSYS is used to do stress analysis, hence achieving the desired outcome.
