NewTRAFOLO Thermal is out — CFD heat transfer

Electromagnetics and heat transfer, from one setup.

TRAFOLO is a 3D simulation platform for power electronics. Two applications — electromagnetics with built-in heat transfer, and fluid dynamics with heat transfer — share one way of working: build the model once, study it twice.

Two products, one platform

Pick the physics you need today.

Two specialised applications for the two physics that decide a power-electronics design — build the model once, study it twice.

TRAFOLO Magnetics

3D FEM for magnetics and losses

Validate transformers, chokes and inductors against specification before the first physical prototype exists. Resolve skin and proximity effects, extract inductance, AC resistance and capacitance matrices, and drive it all with waveforms from your circuit simulator.

Physics
Electromagnetics + built-in heat transfer
Solver
3D finite element — transient or harmonic
Typical use
Flyback, planar and DAB transformers, gapped chokes, induction heating, wireless power
Licence
Academic, Professional, Floating

TRAFOLO Thermal

Convective heat transfer for electronics

New

A finite-volume conjugate heat transfer solver for the thermal side of power electronics: heat sinks, enclosures, potted assemblies and forced-air cooling. Solid and fluid regions are solved together, so you get component temperatures — not just an air flow field.

Physics
Fluid dynamics + heat transfer — conduction, convection, radiation
Solver
Finite volume — steady-state or transient
Typical use
Heat sinks, sealed enclosures, fan cooling, cold plates, potted magnetics

Two studies, one design

Build the model once, study it twice.

A magnetic component is an electromagnetic problem and a thermal problem at once. TRAFOLO gives each its own specialised application — study the losses in one, the temperatures in the other, and keep every result on your own hardware.

Application 01 — Electromagnetics + heat
TRAFOLO Magnetics
3D finite element · transient & harmonic
  • Core loss — Steinmetz-based models
  • Winding loss — homogenisation for litz
  • B-H hysteresis, temperature-dependent σ
▶
◀
Application 02 — Fluid dynamics + heat
TRAFOLO Thermal
Finite volume · steady & transient
  • Conjugate heat transfer, solid + fluid
  • Natural and forced convection
  • Surface-to-surface radiation

Both applications run fully on-premises — models and results stay on your machines.

From CAD to report

Four steps, no scripting required.

Step 01

Geometry

Import CAD or DXF files — 2D profiles extend to 3D — or start from a parametrised template for common core and winding types.

Step 02

Setup

Assign materials from the library, apply excitation waveforms from your circuit simulator, set boundaries and heat sources.

Step 03

Solve

Automatic meshing with local refinement, then solve in parallel across the cores of your workstation or cluster.

Step 04

Post-process

Losses, temperatures, inductance, AC resistance and capacitance matrices — plus fields, plots and parametric sweeps.

Who uses TRAFOLO

Specialised where general-purpose tools are generic.

01

Magnetics designers

Get loss breakdown per winding and per core section, and see where the hot spot actually sits before winding a prototype.

02

Thermal & CFD engineers

A real finite-volume heat-transfer solver with meshing and post-processing handled, so setup takes minutes rather than a day.

03

R&D managers

Replace prototype iterations with parametric studies. Per-user or floating licences, with onboarding and consulting hours included.

04

Academia

A dedicated academic licence for non-commercial work, with verified results in a timeframe a semester allows.
