In this example, a weave structure with two materials is exported to Fluent to run heat computations.

Under the Constituent Materials tab, set the Material ID of the material occupying the pore space by clicking the Pore… button and selecting Pore (Fluid) → Air from the list in the Material Selector.

Then, the conductivity for air from the GeoDict material database is used. Enter the conductivity for Material ID 01 and Material ID 02 manually as shown below.

In the Solver tab, keep the default values, as well as under the Grid tab (Voxels with side length…). With this option, the voxel structure from GeoDict is used as it is.

Click OK to close the dialog and return to the ExportGeo-Fluent section. Click Export to export the structure and simulation settings for Fluent.

The result file (*.gdr) is automatically opened in the Result Viewer. It contains all information about the current export. The corresponding result folder contains the mesh and journal files for Fluent.

To run the flow computation, start Fluent and open the journal file by selecting File → Read → Journal….

After the simulation, the computation results can be visualized in Fluent. For example, the temperature distribution in the structure is shown in the figure below.
