Thermal Actuator Surrogate Model Application
Application ID: 120731
The Thermal Actuator Surrogate Model Application demonstrates how the computational speed can be increased with the use of a surrogate model.
This app demonstrates the following:
- Adjusting input parameters via sliders, with near-instantaneous updates to the solution retrieved from the surrogate model
- Comparing the surrogate model solution with the full finite element solution
- Efficient geometry sampling for data generation to be used for surrogate model training.
The 3D surrogate model has 8 input parameters: 5 input parameters, that include geometry dimension and applied voltage, and 3 input parameters for the x,y, and z coordinates.

This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
