In this work we consider the boundary integral equation describing the

steady state heat conduction taking place in three dimensional enclosure

geometries. For the numerical realization of the Fredholm integral equation,

we use the boundary element method based on the Galerkin weighted

residuals method. Consequently, converting the original integral equation

into a set of algebraic equations. We apply the multigrid iterations to solve

the system of linear equations. To demonstrate the efficiency of this iterative

scheme, we construct numerical example.

Keywords: Heat conduction, Fredholm integral equation, Boundary

element method, Multigrid iterations.
