Since version 2026, Flux 3D and Flux PEEC are no longer available.

Please use SimLab to create a new 3D project or to import an existing Flux 3D project.

Please use SimLab to create a new PEEC project (not possible to import an existing Flux PEEC project).

/!\ Documentation updates are in progress – some mentions of 3D may still appear.

Flux-Activate co-simulation: about

Introduction

Flux offers a coupling with Twin Activate, compatible with Flux 2D and with Flux 3D. This coupling is available for all transient applications.

Implementation

Process tu run a co-simulation between Flux and Twin Activate :
  • Preparation of the Flux project :
    • Standard description: geometry, mesh and physics
    • Specific description: creation of input and output parameters necessary to the coupling
  • Generation of the component for the Flux – Activate coupling
  • Preparation of Twin Activate model: :
    • Set the Flux access path in the preferences in Twin Activate
    • Add a co-simulation block from the palette browser.
  • Configuration of the simulation parameters
  • Running the co-simulation
  • Post processing of results

Examples

Some examples are available starting from the supervisor, in the Open Example context.
