Hybrid Boundary and Finite Element Methods

Hybrid BE-FE Method 

When you compare the advantages and disadvantages (below), you can see that an ideal method would be to combine both methods to form a hybrid of the two.

1. The hybrid solver takes the strengths of both methods and uses them to an advantage.
2. The BEM handles the open regions and linear solution while the FEM handles the non-linear areas.
3. The results are excellent open region solutions with no non-linear convergence problems.
   BEM and FEM: A Comparison
   

BEM Advantages	FEM Advantages
Open regions not a problem Extreme aspect ratios not a problem World space is not truncated Perfectly smooth field solutions	Non linear problems easily solved Easy formulations allow many different types of problems to be solved

 

BEM Disadvantages	FEM Disadvantages
Non linear problems difficult to solve Some problem formulations are not possible	Not well suited for open region problems Extreme aspect ratios can cause problems Truncated world space Fields can be noisy
