Hello everyone,
Im modeling the flow over a car and i placed my car inside a rectangular domain. I use the Ansys workbench default mesher. Im able to mesh the car in isolation but when its inside the domain, the status bar freezes at 'generating mesh for solid'. I believe solid refers to the domain here. Because of this Im unable to generate a mesh. Please help me out here. Thanks! |

I think you need to provide more information. Perhaps a screen shot of your domain with and without the rectangle boundary will help, and also a screenshot of your meshed car "in isolation". One thing to ask, when you say "able to mesh the car in isolation" does this mean that you do not have any bounding surfaces outside of the car? If so then I'm assuming you've imported a solid model and not a fluid volume model, if you catch what I'm saying.

Im using default settings in the ansys mesher. Currently Im not even able to generate a preview for the enclosure. Any advice would be much appreciated. Thanks! |

How did you import the geometry into ANSYS Meshing. Did you import a CAD geometry into Design Modeler? If the car is a solid, you need to essentially take the inverse of the car solid. You can do this in Design Modeler very easily using boolean operations performed on the car solid and an arbitrary "bounding solid" that encloses the car. Once you do this you should have an air solid of the car in an and enclosed volume and the mesher should do what you want.

After you perform the enclosure, does only one part exist? Also, I skimmed over the documentation and it states that you need to ensure that the body you are enclosing is a frozen body. Did you check this? Typically when importing a geometry, the default is to "Add Material" you will want to change this to "Add Frozen". This option is located in the properties view pane when you select the import tree node in the outline view pane.
Sorry I didn't respond sooner, got tied up. |
