Abstract :
The boundary-element method (BEM) is used to solve the underground cable thermal field problem. Because attention is focused on the region boundaries rather than on its interior, the computational effort is reduced very significantly. Examples of application of the BEM include homogeneous soil and multimedia systems. Single and multicable geometries are investigated. The results exhibit accuracy better than can be expected for commonly used domain-type methods, since region truncation with an artificial boundary is not needed
