Dear friends,
I've tried to create velocity inlet profile in my analysis. by below method,

1) Inlet type > velocity inlet
2) velocity specification > Magnitude + Direction
3) Flow direction specification > components

by this way an analysis was solved correctly. However, when I see the velocity magnitude is very less as it was in .csv table file(exported from previous analysis)
But the flow direction seems ok.

Can anyone please suggest, why the velocity magnitude is not considered in this analysis.

Cross check your co-ordinate system for assigning the values and reporting the values. Both co-ordinate sys should be same. I prefer to create one by myself at inlet.
Hope this helps.

Thanks for suggesting. I will check the co-ordinate system.
Though I have not changed the co-ordinate system for both analysis. It was set to global.
I think As per your suggestion, I need to create local co-ordinate system while exporting velocity results. and same sys at Inlet (where the coupling is to be done)
