Abstract

Abstract: Model order reduction of an electro-thermal package model is discussed. This model is an electro-thermal coupled problem with geometrical variation. Due to the coupling and parameter variation, the package model leads to a system of nonlinear parametric differential- algebraic equations (DAEs). This model can be very large-scale which makes simulation computationally expensive. This calls for the application of model order reduction techniques, particularly for parametric model order reduction (pMOR) methods. However, many pMOR methods are restricted to linear parametric models. This motivates us to propose an approach which involves first decoupling the nonlinear parametric DAEs into differential and algebraic parts. Then, the differential and algebraic parts can be reduced separately.
