Introduction to Finite Element Analysis (FEA) and element types used in FEA

This article deals with the overview of Finite Element Analysis (FEA) and types of elements used during Finite Element Analysis (FEA). Common element types used are linear, quadratic, and cubic nature. The cubic element gives a better result than quadratic and linear. Again quadratic gives a better result than linear. ANSYS software uses these types of elements during FEA. Here an attempt is made to highlight the common element types used in ANSYS software.
