General description Neste curso preséntase unha introdución ao método dos elementos de contorno. Usando como modelo un problema de potencial, estudianse o método directo e os métodos indirectos baseados nas formulacións de capa simple e capa dobre para resolver problemas interiores e exteriores en dúas e tres dimensións. Seguidamente descríbese a aplicación do método a problemas de dispersión (scattering) e de radiación acústica, mecánica de fluidos e elastostática. Finalmente, amósanse técnicas básicas de acoplamiento de métodos de elementos de contorno con métodos de elementos finitos.
