What is FEA ? ( Interview Question )

FEA means Finite Element Analysis . FEA is a process in which simulate loading conditions on a Design and determine the Design's response .

Suppose we have a 3D model and shape of model is very complicated  , have infinite number of unknown cause is formula's not available in mathematics to determine the responses  for this shape so we divide the shape of model in some small shape those formulas  is available in mathematics thus we say model have finite number unknown , hence the name is finite element Analysis.

Divide in four rectangle and two quarter circle which formula's available in mathematics to determine Design responses , dividing process called Meshing .

The First CAD software...

 the first true CAD software, a very innovative system (although of course primitive compared to today's CAD software) called "Sketchpad" was developed by Ivan Sutherland as part oh his PhD thesis at MIT in the early 1960s. Sketchpad was especially innovative CAD software because the designer interacted with the computer graphically by using a light pen to draw on the computer's monitor.
