English Description：
Application backgroundThis code can be used for solving conventional finite element method 2D problems involving quadratic quad elements. It gives the elemental stiffness matrices, assembly of elemental stiffness matrices and allocation to global stiffness matrix. The code has been written clearly mentioning the functions for all the things involved in manual solution of finite element method problemsKey TechnologyIt can be used to solve two dimension domain based problems of heat transfer, structural mechanics, fluid dynamics and various other relevant problems. The quadratic quad element gives much better accuracy than linear quad elements in terms of increased nodes in each element. Thus this code shall prove very helpful to the beginners in the finite element analysis.
