These customized tasks can perform advanced Fluent operations that are tailored to your organization. You can also expand the standard watertight geometry workflow by creating custom journals. Now you have the ability to tweak some standard variables that control the mesh quality. However, you can insert additional tasks into the task-based workflow if they are needed.įor example, you may wish to further refine the volume mesh. If you wish to use the latest Mosaic meshing technology, select “Poly-hexcore.”Īt this point, the standard watertight geometry workflow is complete, and you are ready to mesh your model.

Then, you can access the full suite of conformal volume meshing methods: These will only be added on fluid region walls. You can use Mosaic meshing technology to automatically link fine and coarse meshes together.įrist, you can choose to add boundary layers in the “Create Volume Mesh” panel. However, maintaining a fine mesh throughout the bulk would be computationally expensive. When the volume meshing starts, Fluent will make a fine mesh at the boundary layers. You are now ready to start volume meshing your model. Just remember to click “Update” once you are done verifying all the boundary types. If you select multiple names and right-click, you can change multiple boundaries or regions into the same type. You can change a boundary or region’s name and type as needed. This means you can now move your workflow into a Linux environment.Īdvanced Options to Speed Up Surface Meshing of CFD GeometryĪs a best practice, verify that the boundary and region types were assigned properly before volume meshing. It will be much faster to read the pmdb geometry than the original CAD geometry.Īnother advantage with the PMDB file is that it is operating system-independent. The next time you need to read in the same model, try reading in the PMDB file.

The Benefits of Using Native Fluent FilesĮvery time you import the CAD model into the Fluent task-based workflow, the software creates a native version of that file (.pmdb). You are now set to import the motor model into Fluent. If you include these strings in the entity name, Fluent will know to define these entities as inlets, outlets, symmetry planes and more. In fact, make it a habit to add descriptive strings to the names of other entities, like That will automatically identify it as a fluid region within the watertight geometry workflow. While working on your geometry in SpaceClaim, there are a few other tips and tricks that might make your life easier down the road.įirst, include the string “fluid” in the name of the cube around the motor geometry.
