It is often impossible to determine the optimum detector geometry, thermist
or doping and operating conditions prior to fabrication. We therefore sugge
st a software approach. A computer code, which allows to simulate the heat
transport and electrical coupling, has been developed and is applied to act
ual calorimeters. The overall agreement between calculated detector feature
s and corresponding experimental findings is found to be good. (C) 2000 Els
