Local Coordinates A local coordinates system whose origin is located within the element in order to simplify the algebraic manipulations in the derivation of the element matrix. The use of natural coordinates in expressing approximate functions is advantageous because special integration formulas can often be applied to evaluate the integrals in the element matrix.
Exact Solutions In mathematics and especially physics, an exact solution is a solution to a problem that encapsulates the whole mathematics or physics of the problem without using an approximation. Analytic solutions
Major steps in Finite element Analysis The finite element analysis requires the following major steps: Discretization of the domain into finite number of sub domains. Selection of interpolation functions.
