An Improved Dynamic Compact Thermal Model for Non-Linear and Non-Homogeneous Heat Diffusion Problems

We address the problem of generating Dynamic Compact Thermal Models for non-linear and non-homogeneous heat diffusion problems. We propose a novel Model Order Reduction technique that is based on i) a specifically designed discretization that properly models the non-linear behaviour of different materials, and ii) the introduction of an improved Hyper Reduction method that dramatically reduces the problem dimension. Our experiments show that our method performs similarly to full Finite Volume simulation in terms of accuracy, while being much more computationally efficient.
