########## JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY ANANTAPUR B.Tech (ME) - III-II Sem L T P C 0 0 3 1.5 (20A03606) COMPUTER AIDED DESIGN LABORATORY Course Objectives:

- • To use the commercial Finite Element packages to build Finite Element models and solve a selected range of engineering problems.
- • To validate a Finite Element model using a range of techniques.
- • To communicate effectively in writing to report (both textually and graphically) the method used, the implementation and the numerical results obtained.
- • To discuss the accuracy of the Finite Element solutions.

########## Course Outcomes

- • Ability to solve engineering problems using the commercial software's such as ANSYS, SIMUFACT, ABAQUS,SIMULIA, Mathematical, MATLAB,GNUOctave, Scilab, MAPLE/ COMSOL.

########## List of Experiments:
