In this tutorial, we will learn how to set up a simple CFD simulation case for flow over a car. In this tutorial, the procedure of geometry preparation, meshing with fluent meshing, setting up boundary conditions, calculation of lift and drag and viewing the results in fluent is demonstrated.

Haha. You are being too kind :)

Your video is very helpful. I have a question. I understand that the areas used in the calculation of lift and drag are different. If I input the projected area used for drag calculation in the reference value of Fluent, will this same area be used for lift calculation? Shouldn't the projected area in the y-direction be used for lift? I would appreciate it if you could answer my question.

I'm having a hard time to create a encolsure of the car I modeled.. Spaceclaim gives this message: Unable to intersect bodies. Cannot merge bodies. (Operation failed because the faces and edges would combine in a way that does not form a valid solid or surface.) An error occurred while creating the enclosure - the selected body could not be subtracted from the enclosure body. I spent like 120 hours modeling this car, does anyone know how to solve it? I used Catia Imagine and shape and then made a flat floor and filled the side (modeled just half car) with surfaces made in Generative Shape Design module. The used the "Close Surface" tool to turn it in a Solid....

I can't set 0 at one side of enclosure why?

Any difference in end results if CFD is done with tyres and without tyres.. and any particular reason for doing this with half body sir...?

@cfdbabaopenfoamansyscfd2972 10 месяцев назад

Yes results will change and drag may increase if tyres are considered. I have considered half body since our geometry is symmetric and it also reduces the total mesh count.

Dear sir, I have developed a shape of body using nx but now it's hollow and for analysis I need it filled like solid for analysis I build the body it's said in design tree as subdivision body pls tell the step to fill whole body from inside. In short I have designed the outer shell of car but infact it's hollow from inside so now while using ansys it shows surface instead solid Even in above video of yours sir you draw shape using nx shape and adjusting cages but you convert in solid iwant to know how you conver subdivided body into solid body pls.

@cfdbabaopenfoamansyscfd2972 9 месяцев назад

Hello. Sorry but I don't have much experience with NX. Also I got this CAD directly from internet. I did not create it.
