Hello guys, i am Mathias from Germany, studying mechanical Engineering. I am doing a Group Project work at the Moment about the aerodynamics of a formula Student racecar. At the Moment we have lot of Problems with the Generation of the Volumemesh. I try to describe the Problem as good as possible:
I generate a prism layer on our car, the rest of the volume is filled with tets. after the generating of the mesh is finished, the surface of the car is not the original surface. The prism layer is always like a solid Body, to Support your Imagination, its looking a bit like a car in winter, when the snow is laying on top of the surface around the car. So the car is just looking "swollen".
I took the Pictures for you. The Pictures where only taken to Show the Problem and test different Settings to get this Problem solved, so dont wonder about the small wind tunnel! Furthermore the prism layer is three layers thick, so its not that "swollen", with 10 prism layers the car was really getting fat!
By the way, i did meshes for the formula Student Team last year, there i didnt had this Problem with the prism layers.
I hope someone knows a possible way to get a solution for this! We are using Fluent 17.2, before we used 16.1 if this makes a difference.
