ROM Tutorial
This tutorial aims at briefly explaining how to use the R.O.M. (Reduced Order
Modeling) tool.
Finite element models may involve a large number of degrees of freedom so that
full simulation, especially in case of transient analyses, can be prohibitively
expensive. The aim of the R.O.M. tool is to make model simplifications or limit
the available results in order to obtain accurate, but fast solution during
simulations.
The following parts indicate how to perform a reduction with two different
examples: condensation of an accelerometer model and reduction of an
electrostatic-structural coupled system.
Condensation: Reduction with Single DOF & Load Cases
Before using the R.O.M tool, you first have to provide a finite element model in
ANSYS. For the following examples, use an inertial accelerometer model, that
consists of a structural mass supported by four thin beams clamped at their
extremities, as shown in Figure 39.
