2 Creating and manipulating geometric models using curves, surfaces, and solids.
3 Applying concept of 3D modeling, visual realism,and CAD standard practices in engineering design
4 Developing mathematical models for Boundary Value Problems and their numerical solution.
5 Formulating solution techniques to solve non-linear problems
