Hi there. I'm working with a 3D model of an automobile. Because of the lack of compute capacity I'm trying only a half of the model, and then by symmetry I can get the hole problem. But there is a problem in the boundary condition in the centerline of the car. I was thinking about get this conditions of an 2D analysis. Is it posible? Do you think it's a good idea?

Thank you very much in advance

I don't know if it isn't posible or if I haven't explained it well. If I know the velocity condition in a face, can I put it as a boundary condition in a 3D simulation?

i have a problem in determine my boundary condition of chemical reactor tank where this tank don't have output and input.

the tank is just a cylinder.

can you give me a suggestion on this problem?

i want to analysis the flow pattern in this chemical reactor tank when the blade (propeller) is rotating with velocity of 146.16 rad/s.

i need you respond urgent...

please help me..
