Mechanical Design of components has decisively moved away from Rule and formula-based calculations towards more simulation-oriented Design.
The backbone engine that runs any simulation tool, evolves from Finite Element Analysis.
So far, FEA has been locked in with commercially available software tools like ANSYS, ABAQUS, and NASTRAN.
However, with recent advances in Artificial Intelligence, entire field is moving towards programming and automation.
Hence, Finite Element Analysis is a must have knowledge for a modern-age mechanical engineer.
