So far, I have completed more than 15 industry-oriented projects under the “Computer-Aided Engineering” Master’s Certification Program. Some of the projects are the analysis of “Frontal car crash-BIW”, “Sidecar crash-BIW”, and “Roof car crash – BIW(Quasi-Static analysis)” using HyperMesh and Radioss. Also, pre-processing in ANSA and HyperMesh on different components of car like ‘Hood’, ‘Side door’, and ‘Back door’, ‘suspension Assembly’, and ‘IP substrate’. More recently, I have completed “Python for Mechanical Engineer”, in which I did scripting on the ‘Newton-Raphson Method’, ‘Curve Fitting’, ‘Air Standard Cycle’ and ‘Data Parsing’. Learning these skills and working on projects boosted my confidence greatly. It has also given me the conviction to look towards my future endeavors with optimism.
