1 The SUNRED program: models & algorithms Equation to be solved (2D case): The structure model: Cell, center and boundary (terminal) nodes. Different colors mean different materials.

2 Network models for FD solution: Steady-state circuit models of a single cell: a.) “Current” excitation (heat flux), b.) forced “voltage” (temperature). The time-discretized resistive equivalent of a cell, corresponding to a reverse Euler time step. Successive reduction of the model network The SUNRED program: models & algorithms

3 The THERMAN program: models & algorithms The model: Rectangular block, Arbitrary number of homogenous layers Arbitrary number of 2D dissipating shapes on layer interfaces Buried dissipating shapes are permitted Heat conducting bonds can be modeled Boundary conditions:

4 The THERMAN program: models & algorithms Different structures that can be analyzed by the Fourier method Solution method: Fourier expansion using Fast Fourier Transform

5 SUNRED examples Thermal transient movie window of a membrane structure Study of a sensor package with two chips inside DC simulations results to support the optimisation of a cable connections in power packages Study of a micro-cantilever based on its SEM image
