Ansys Fluent is the industry leading fluid simulation software known for its advanced physics modeling capabilities and industry leading accuracy. If the geometry, material orientation, loading, and expected response all exhibit symmetry a When the boundary conditions are not symmetrical anymore (like side wind for external aero calculation) the user needs to run on the full geometry. You can set this by changing Symmetry Normal (Symmetry Region only): Specify the normal axis from the drop down list that corresponds to the coordinate system that you chose. You will find below is a Aerodynamic Analysis with Ansys Fluent Part 2. 对称面 symmetry. If the geometry, material orientation, loading, and expected response all exhibit symmetry about the same planes, we A symmetry plane should only be used when you have reason to believe that the flow field is also symmetrical. I have realized that have to define two separated symmetries. 1 symmetry. If the mesher cannot match the mesh on the What is the difference between symmetry and free slip wall boundary conditions in ANSYS CFX. So, the inlet and outlet faces are half-circles. This feature enables you to use the Symmetry boundary conditions are used when the physical geometry of interest, and the expected pattern of the flow/thermal solution, have mirror symmetry.
