![]() 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. Why You Should Name Your Model’s Entities in SpaceClaim The volume will take the shape of the void between the boundaries of the cube and the motor. The flow volume will be extracted as part of the Surface Mesh operation in Fluent. It also resolves the intersection between the cube and any part of the motor. Share Topology combines all overlapping faces between two solids into one face. To do this, draw a cube around the motor and then use the Share Topology function. If you are creating an internal flow volume, then the capping tools in Fluentmakes extraction easy.įor external flow simulations, like the air flow cooling a motor, we need to create an outer flow boundary in SpaceClaim. Share Topology defines a flow region without Boolean operations. ![]() Moving the Flow Volume from ANSYS SpaceClaim into ANSYS Fluent Now, click on “Switch-to-Solution,” to bring the mesh into a familiar Fluent interface.īut, what if you are looking to simulate a more complicated model - like air cooling an electrical motor? Let’s see some tips and tricks in the watertight geometry workflow to get this complex model pre-processed in no time. You are presented with several steps, like: If you start with a relatively simple model, getting through the task-based workflow is straightforward. But even this expert is sold on the simplicity of ANSYS Fluent’s task-based workflow for watertight geometries. I know shortcuts, tricks and application program interfaces (API) from memory. I admit that I am a computational fluid dynamics (CFD) meshing wizard.
