The finite element Modeling is a numerical modeling and analysis technique used by engineers, scientists, and mathematicians to obtain solutions to the differential equations that describe, or approximately describe a wide variety of physical (and non-physical) problems. Physical problems range in diversity from solid, fluid, thermal and soil mechanics, to electromagnetism or dynamics. The underlying premise of the method states that a complicated domain can be sub-divided into a series of smaller regions in which the differential equations are approximately solved. By assembling the set of equations for each region, the behavior over the entire problem domain is determined.

The FEM technique most predominantly used in our field of research which include simulation and testing. Studies related to 3D Printing, Nozzle design, Mechanical and thermal analysis, fluid flow analysis are being carried out in different computer software platform based on FEM.
