Hope will find some guidance and explanation on the page of CFD 2013 altoghter with the other tutorials and etc.ģ) The 2D analysis you are talking about.to be honest i really do not get it. In brief computational volume from one package to be used in another one.Ģ) Advection scheme.i will do my best to find more information about it. Regarding your piece of advice about creating my computational volume in Solidworks, you think it is possible to assign Boundary Conditions when i run it in Autodesk CFD 2013. Even the tyres are simple circles which have been extruded, no treads nothing.ġ) Yes i have assigned gauge pressure as a boundary condition both at my intlet and outlet of the wind tunnel. Actually the CAD model of the car is just a closed body volume, 4 tyres(without any bars between them and the body) and the undertray with the diffuser. Thank you for the response and apologize for my late reply! Also i forgot to mention that our primary aim is to track the levels of downforce generated by a flat undertray and a diffuser at the end. Hope, more experienced people will drop some lines! Generally, i would extremely appreciate any piece of advice/guidance for our analysis, in terms of Physical Boundary Conditions, Type of Flow Analysis and etc. However, there is some distance between the wheels and the bottom of the computational volume ( equivalent of wind tunnel ) which makes me feel a little bit worried about the accuracy of your results. Thanks to the Motion Setup, we assigned Rotation to the 4 wheels. So far, after we created our computational volume ( equivalent of a wind tunnel ), we assigned boundary conditions at the inlet(NORMAL velocity) and the at bottom (Vz velocity component, with the same magnitude as at the inlet, of cource). My appeal is if anyone can suggest a reasonable and efficient way of simulating moving road(ground effect) like during a normal competition. The CAD package we are using is SolidWorks, but we are running our flow analysis in Autodesk CFD 2013. I couple of guys and i are desining the aero/body package of a Formula Student race car. Here is in brief the situation in which i am.
