Finite Element: Introduction to Finite Element Method

Finite element method is a numerical method that can be used
for solving engineering problems.
It is particularly useful for problems involving complex geometries, combined
loading and material properties, in which the analytical solutions are not available.
FAQ: Is this method accurate?... Yes, for simple problems and if material properties
and loading condition are modeled very close to the actual conditions. No,
especially when the problems to be solved are too complex.
Among the sources of error involved in this method are…
Geometrical simplification;
Interpolation function;
Material properties;
Round‐off, etc.
