Export heat simulation (voxel)
To generate a journal file and a mesh file for a heat computation with Fluent, select Export Heat Simulation (Voxel) from the pull-down menu in the ExportGeo-Fluent section.

Important! The same results can be achieved with the ConductoDict module directly in GeoDict. In general, this is the recommended way if ConductoDict is in your GeoDict license, since the GeoDict solvers are optimized for voxel structures and therefore faster and more memory efficient for this use case. |
In the ExportGeo-Fluent – Export Heat Simulation dialog, choose a Result File Name (*.gdr) according to your current project. The result file contains all information about the current export. The corresponding result folder contains the mesh and journal files for Fluent and the chosen structure as GDT file. The options for the Fluent solver are organized under the tabs Constituent Materials, Solver, and Grid.
Constituent Materials
The thermal conductivities of all materials present in the structure are defined in the corresponding fields under the Constituent Materials tab.
Solver
All settings for the Fluent solver and the simulation parameters are defined under the Solver tab, and are already explained for Export Flow Simulation (Voxel). In contrast to flow simulations, Fluent V. 6.2 is not supported for heat simulations.
Grid
Structures in GeoDict are always based on voxels. With Voxels with side length …, the voxel structure from GeoDict is exported as-is to Fluent.
If the simulation in Fluent should be done on a boxel grid, the size of these boxels can be entered with Boxels with…. With this option, every voxel in GeoDict is mapped on a boxel with the given size.
