SimScale supports fluid dynamics (CFD), structural mechanics (FEA), thermodynamics, and electromagnetics — and any combination of these within a single workflow. Common pairings include conjugate heat transfer (CFD + thermal), thermomechanical analysis (thermal + structural), electromagnetic-thermal coupling (EM + thermal), and CFD-FEA one-way coupling where aerodynamic pressure loads are transferred directly onto a structural mesh. All physics domains share the same geometry, mesh, and results infrastructure — no manual data transfer between tools required.
SimScale supports both tightly coupled and one-way coupled multiphysics workflows. In one-way coupling — the most common approach — results from one analysis are transferred as inputs to another: CFD pressure loads mapped onto a structural mesh for blade stress analysis, or electromagnetic losses used as heat sources in a thermal model. For tightly coupled problems like conjugate heat transfer, fluid and solid thermal equations are solved simultaneously within a single simulation. Both approaches run within the same platform, sharing geometry and mesh infrastructure, so there's no manual data transfer between tools.
Any industry where products operate under combined physical loads. Electronics and high-tech teams use EM-thermal coupling to prevent component failure in power electronics. Automotive and EV engineers combine CFD, FEA, and thermal analysis across battery packs and drivetrains. Turbomachinery and energy sector teams use CFD-FEA coupling to validate blade integrity under aerodynamic and thermal loads. AEC engineers combine airflow and thermal analysis for building comfort and energy performance. If a product generates heat, moves, or carries current — multiphysics applies.
Running multiphysics on traditional desktop tools typically means separate licenses, separate tools, and manual data transfer between them — introducing both overhead and error risk. SimScale manages all physics domains within a single cloud-native environment, sharing geometry, mesh, and results infrastructure. Engineers can run coupled analyses without switching tools, and cloud HPC means the additional computational cost of coupling solvers doesn't create hardware bottlenecks.
SimScale's Physics AI supports multiphysics workflows through surrogate models trained on coupled simulation datasets — delivering near-instant predictions for problems that would otherwise require hours of solver time. Engineers can train Physics AI models on their own multiphysics results and deploy them for rapid design space exploration across coupled domains. Engineering AI handles the workflow orchestration — automated meshing, boundary condition setup, and solver configuration — reducing the specialist knowledge typically required to set up a coupled simulation correctly.
