The advantages of the boundary element method over the FEM that no elements are required inside the domain, also has some disadvantages: loading may only be applied at the boundary, but not inside the domain. A number of problems exist where applying loading inside the domain is necessary, for example
•
where sources (of heat or water) or forces have to be considered inside the domain
•
where self weight or centrifugal forces have to be considered
•
where initial strains are applied inside the domain, for example when material is subjected to swelling.
