Model order reduction of 3D electro-thermal model for a novel micromachined hotplate gas sensor

In this paper we present an automatic, Arnoldi-based model order reduction of a 3D electro-thermal model for a novel sensor device. Model order reduction is essential for achieving a quickly evaluable, yet still accurate, macromodel of the device, needed for system-level simulation. We present below numerical simulation results of the full-scale finite element model and the compact-reduced order model, and show how the nonlinearities in the input function can be treated even with the linear reduction algorithm.
