Running a Full-Order Model (FOM) Simulation in Twin Fabrica

Twin Fabrica lets you run high-fidelity Full-Order Model (FOM) simulations to compute steady-state thermal behavior across a defined geometry. These simulations use your model's thermal configuration, including materials, heat sources, and boundary conditions.

This section guides you through building and running a FOM simulation.

1. Prerequisites: Thermal Setup Validation

Before starting, ensure your thermal model is fully defined with:

  • ✅ All materials correctly assigned to geometrical entities
  • ✅ At least one heat source configured
  • ✅ One or more boundary conditions (e.g., Dirichlet, Neumann, Convective) applied

When completed, go to the PHYSICS tab to continue.

2. Access the FOM Simulation Window

In the PHYSICS tab, click the FOM Simulation button in the toolbar.

A dedicated window will open where you can set solver options and run parameters.

3. Check for Full-Order Model Availability

Twin Fabrica will show a warning dialog if the Full-Order Model hasn't been built yet.

⚠️ The simulation cannot run until the model is built.

4. Build the Full-Order Model

To build the model:

  • Click the BUILD FOM button in the PHYSICS tab.
  • Twin Fabrica will compile the thermal system, incorporating your geometry, materials, heat sources, and boundary conditions.

⏳ Build time varies with mesh size and the complexity of space-dependent functions.

5. Confirm Build Completion

The logger panel at the bottom will display a confirmation message when compilation succeeds.

Your Full-Order Model is now ready for simulation.

6. Launch and Run the Simulation

Reopen the FOM Simulation window. Inside:

  • Click COMPUTE to start the solver and calculate the steady-state temperature field.
  • Computation time ranges from seconds to minutes, depending on system complexity.

7. View Simulation Results

After completion:

  • The temperature field appears automatically in the 3D viewer.
  • Use this visualization to analyze heat distribution, thermal gradients, and potential anomalies.

If results seem incorrect, adjust your heat source, material, or boundary condition settings. Then rebuild the FOM and run another simulation to verify.
