Calculation volume with alternative hot spot locations and cell definitions. Calculation volume with power source generating the hot spot between two cell elements (yellow depicted). The image shows an example of a small calculation volume and the convention for cell labeling of the algorithm. The power source for most cases is assumed to lie within the symmetry plane at x = 0. Half of the total applied power reaches the cell with index i = 1 and j = 1 for r and x respectively. For simulating a planar heat sink the power source is shifted to a different position between cell elements at position xf-1 and xf (also yellow depicted). In that case half of the entire applied power is assumed to reach the cells at position xf-1 and xf.
