Model reduction of linear large-scale dynamic systems is already quite an established area [1]–[3]. In a number of papers (see references in [3]), the advantages of model reduction have been demonstrated. In the present paper, we describe a software tool to perform moment-matching model reduction via the Arnoldi algorithm directly to ANSYS finite element models. We discuss the application of the tool to a structural mechanical problem with a second order linear differential equation (ODE). Its successful application to the first order case of electro-thermal modeling is demonstrated elsewhere [4], [5].
