Abstract:
Our goal in this research is to introduce the basic principle and tools of the finite element method in the form L(u )=f (x) In chapter one We gives some definitions, theorems, ·
remarks, and problem that is we need it to simplify .the main topic
We discuss some fundamental results which include ·
the approximation problem and the internal
H1 approximation of . (Ω)
In chapter two We discuss some fundamental results ·
.which include the finite elements
In chapter three We show the application of the finite ·
element method for solve the boundary value
.problems We explain the effect of numerical integration and ·
.abstract error estimate
