COMSOL Day: Simulation Apps & Digital Twins
See what is possible with multiphysics modeling
Modeling and simulation is no longer limited to the expertise of a few individuals within an organization. The availability of simulation tools throughout the product or process design workflow — from R&D to the factory floor — allows for a more collaborative and innovative approach to problem-solving. Now, even those without prior modeling knowledge can contribute to the process, leveraging the expertise of modeling experts and advanced techniques like digital twins and surrogate models.
To facilitate this collaboration, the Application Builder in COMSOL Multiphysics® allows modeling experts to create custom apps with user-friendly interfaces that can be used by scientists and engineers without modeling experience. Taking this a step further, COMSOL Compiler™ enables organization-wide use of standalone simulation apps without licensing restrictions.
By using the Application Builder and COMSOL Compiler™ together with the COMSOL Multiphysics® platform's built-in Model Builder and Model Manager tools, engineering organizations can establish an efficient, collaborative, simulation-based environment, supported by the realistic and predictive capabilities of digital twins and surrogate models.
Join us for this COMSOL Day to learn how the Application Builder and COMSOL Compiler™ can revolutionize your organization's approach to simulation, making advanced tools accessible and fostering a culture of collaborative innovation.
Schedule
Physics-based simulation apps can be customized for specific needs and used to democratize access to advanced simulation tools among a broader community of engineers and scientists. With COMSOL Compiler™, you can transform these simulation apps into standalone executable files that can be distributed and run without license restrictions. This functionality enables more project stakeholders from various teams to leverage modeling and simulation, facilitating interactive, real-time decision-making based on accurate results.
New functionality in COMSOL Multiphysics® for creating surrogate models further enhances this capability, enabling lightning-fast simulation apps that provide a highly interactive user experience. Surrogate models also allow simulation apps to be integrated into digital twins, expanding their real-world applications.
Join us in this session to get an overview of this COMSOL Day, throughout which we will explore simulation apps, digital twins, and surrogate models. We will also highlight how customers have saved both time and resources by creating and using compiled simulation apps and digital twins.

Numerical simulations represent a substantial advancement in engineering and science. Research consistently indicates that conducting effective simulations provides significant benefits to companies by enabling their teams to develop new products at reduced costs and deliver them on schedule more frequently. These advantages incentivize companies to increase adoption of simulation by both experts and nonexperts.
Simulation usage among nonexperts, known as "democratization," is a process that enables nonengineers and engineers at all levels to benefit from simulation without requiring extensive education and training to become simulation experts.
One excellent opportunity to democratize simulation is through simulation applications developed by simulation experts to ensure high-quality results. These applications are then made accessible to a broader audience through a user-friendly interface.
AltaSim Technologies has leveraged its expertise in successfully developing and deploying simulation applications for numerous companies and will share their experiences during this talk.
In this session, we will cover the capabilities of the COMSOL Multiphysics® software for developing user-friendly simulation apps and digital twins. We will demonstrate how the Application Builder is used to quickly create simulation apps with custom user interfaces that anyone can use.
The session will also cover the new features in COMSOL Multiphysics® for data-driven surrogate models and timer events, which are essential for creating responsive, interactive digital twins.
Join us to learn how these tools are transforming the use of simulation technology.

The Application Builder in COMSOL Multiphysics® can be very valuable even to experienced COMSOL® users by providing the ability to coordinate a custom user interface (UI) with custom Java code, especially with the recently added capability to use Application Builder pages from the Model Builder interface.
One example of this capability is the ability to deal with irregularly changing boundary conditions in a time-dependent simulation. In these cases, efficient simulation requires coordination between changes in boundary conditions and time points at which to force simulation evaluation. In addition, the time scale of each change can be coordinated with function-smoothing parameters.
This talk will demonstrate a UI that is based on simple tables for specifying pulses and other characteristics of a time-dependent battery simulation. While the UI is straightforward, the power of the approach is the Java code behind the UI. This code calculates ideal time-dependent simulation parameters and seamlessly integrates them into the overall simulation, while also adjusting output, including the display of results.
Simulation-data-driven surrogate models in COMSOL Multiphysics® significantly increase computational speed while maintaining the same accuracy within their applicable data ranges as high-fidelity multiphysics models, making them useful for efficiently approximating simulation results.
COMSOL Multiphysics® provides an ideal environment for generating the physics-based training datasets used by surrogate models. These models can be incorporated into simulation apps, leading to a more interactive user experience and encouraging broader use of simulation within organizations.
Join us in this session to learn more about creating surrogate models. We will present techniques for effective data generation using design-of-experiments methods and walk through the subsequent steps to train a surrogate model. We will also demonstrate how to incorporate surrogate models into simulations apps.
Tech Lunches are informal sessions where you can interact with COMSOL staff and other attendees. You will be able to discuss any modeling-related topic that you like and have the opportunity to ask COMSOL technology product managers and applications engineers your questions. Join us!
