Ansys Projects
ANSYS Multiphysics/Structure mechanics module.This code is based on the Finite element method and is capable of performing static (stress) analysis, thermal analysis, modal analysis, frequency response analysis, transient simulation and also coupled field analysis.
Projects based on this topic is for Mechanical , Physics and Electronics engineering students. I am giving few ideas based on this software.Moreover , you can analyze any machine using this tool.

Project ideas :
