Time-Dependent Optimization

Application ID: 12677

This tutorial demonstrates how to compute the periodic steady-state solution of a nonlinear model problem using an optimization solver. The solver modifies the initial conditions at the beginning of a period to match the solution at the end of the period.

The model solves much faster using this combination of optimization and time dependent solver compared to when using the time dependent solver alone. The reason is that the solution does not have to be computed for a large number of periods in order to reach steady state.

This application was built using the following:

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
