Boundary or Finite Element Analysis? When to use each method.

Would BEM or FEM provide the best analysis for your specific problem?

Boundary element method ((BEM÷) versus Finite element method ((FEM÷)

Advantages of boundary element method

•  Open regions are not a problem v you can calculate fields external to the problem that you are looking at.

•  Extreme accuracy for field solutions

Advantages of Finite element method

•  Non-linear problems are easily solved

•  Easy to extend to transient problems

Advantages of using both BEM and FEM

•  You can compare results when using both methods

•  Choose the right technology to match the problem you are solving

There are software solutions that allow you to choose either or both methods to get the right answer, such as those offered by Integrated Engineering Software .
