Generic Issues in Numerical Modelling
Numerical simulation of thermal and mechanical behaviour of microelectronic systems and subsystems is an increasingly important aspect of their design; appropriate simulation is a vital component of any ‘right first time’ philosophy. Many excellent numerical modelling packages exist which enable simulation of thermal and mechanical behaviour, but the usefulness of simulation results depends crucially on the users’ understanding of the problem to be solved, the numerical issues involved and the context in which the simulation results are to be used. This paper summarises issues to be considered before simulations are performed and then proceeds to consider specific issues in the choice of discretisation of space and time.
