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.

SIMULIA XFlow

SIMULIA XFlow offers a unique approach to computational fluid dynamics (CFD) by using a particle-based Lattice-Boltzmann method. This allows you to skip the traditional, time-consuming meshing process and move straight into simulating complex moving geometries or multiphase flows. You can accurately predict aerodynamic performance, free-surface flows, and fluid-structure interactions without the numerical instability often found in grid-based solvers.

The platform is designed for engineers in high-stakes industries like aerospace, automotive, and energy where transient effects are critical. You can simulate everything from vehicle water wading and cabin climate control to aircraft landing gear deployment. By reducing the manual effort required for geometry preparation, you can run more design iterations in less time and improve the overall performance of your physical products.

SIMULIA XFlow Features

  • Meshless Solver. Eliminate the traditional meshing process entirely to save time when preparing complex geometries for fluid simulation.
  • Moving Parts Simulation. Simulate complex structural motions with ease as the particle-based approach handles changing boundaries without manual grid updates.
  • Adaptive Refinement. Save computational resources by automatically increasing simulation resolution only in areas where high-detail fluid flow occurs.
  • Multiphase Flow. Analyze interactions between different fluids, such as water splashing or fuel tank sloshing, with high numerical stability.
  • Thermal Analysis. Calculate heat transfer and radiation effects within your fluid domain to optimize cooling systems and thermal management.
  • Acoustic Prediction. Predict aeroacoustic noise generation directly from your transient simulations to design quieter products and environments.
