The coupling of the Boundary Element Method (BEM) / the Traction Boundary Element Method (TBEM) and the Method of Fundamental Solutions (MFS) is proposed for the transient analysis of acoustic wave propagation problems and conduction heat transfer, thereby overcoming the limitations posed by each method. The full domain is divided into sub-domains which are modeled using the BEM/TBEM and the MFS, and the sub-domains are coupled with the imposition of the adequate boundary conditions. The
