COMSOL Multiphysics

COMSOL Multiphysics gives you a unified environment to simulate designs, devices, and processes across diverse engineering and scientific fields. You can model coupled or multiphysics phenomena by combining any number of physics interfaces into a single model. This flexibility allows you to move beyond single-physics limitations and capture the real-world behavior of your products more accurately.

You can build your own simulation apps using the Application Builder and distribute them to colleagues or clients via COMSOL Compiler or COMSOL Server. This democratizes simulation, allowing team members without modeling expertise to run their own tests. Whether you are working in electromagnetics, structural mechanics, acoustics, or fluid flow, you can manage the entire modeling workflow from geometry creation to physics setup and results visualization within one interface.

FLOW-3D

FLOW-3D gives you a powerful toolset for modeling complex fluid motion with a specific focus on free-surface flows. You can simulate how liquids interact with solid structures, track bubbles or droplets, and analyze thermal effects in high-precision engineering environments. It uses a unique grid-based approach that simplifies your meshing process while maintaining extreme accuracy for moving boundaries and intricate geometries.

You can apply this technology across diverse fields including civil hydraulics, metal casting, and microfluidics. Whether you are designing a dam spillway or optimizing a laser powder bed fusion process, the software provides the physical insights needed to reduce physical prototyping costs. It is designed for professional engineers and researchers who require high-fidelity results for transient, three-dimensional fluid dynamics problems.
