Flow Trajectories Assymetric
 
Hi,

I am attempting to model the air flow around the passenger cabin of a car in order to find a way of optimizing it.

No matter what i do (in terms of inlet velocity, static pressure, position of flow etc), always the flow trajectories are asymmetric.

I've tried adding a symmetry boundary condition, however when i change the min and max Z values around, the flows are very different.

Does anyone have an explanation for this, or a way to solve this?

Thanks
