hi to all

I have tried a model in 3d multiphase problem which cover +and - coordinate of y-axis.when I giving inlet velocity and initialize my problem, velocity convert to negative so flow direction change. I am not getting exact profile.

I have done my model in icem cfd.

Can anybody help me regarding my poblem.

Thanks in advance

I haven't ever had that problem before as the flow at the inlet should be specified as normal to boundary and therefore the flow should be in the correct direction.

If you are particularly concerned that the model straddles +ve and -ve coordinates then you could always translate the model in Fluent to make it all positive. I doubt however this will have any impact.
