This program was developed in collaboration with three classmates. In summary, it computes a sensitivity analysis of a user-defined geometry, loading, and boundary conditions, using nodal displacement as an input.
The user can choose from three different objective functions:
- strain energy
- displacement
- von Mises stress
Three different types of sensitivity analyses were implemented for each objective function:
- global
- semi-analytical (adjoint)
- analytical
Finally, a rudimentary optimization algorithm was implemented. It utilizes the results of the sensitivity analysis to perform a shape optimization of the given geometry.
In general the workflow looks as follows:
Define inputs in updated GiD interface → Perform calculations in MATLAB → Visualize .vtk files in ParaView
