Direction of Velocity 1 with Axi Symmetric

[pilafa]

Hi,

The image attached shows my axi-symmetric model. It is built in the xy plane, x=0 being the symmetry axis.
The image also shows the velocity along the "r" axis at inlet (Velocity 1 is +0.001).

To have this, I had to define it negative:

Code: Select all

Boundary Condition 1
  Name = String "inlet"
  Target Boundaries(1) = 1
  
  Normal-Tangential Velocity = Logical True
  Velocity 1 = Real -0.0001
  Velocity 2 = Real 0.0   
  
  Temperature = $TCOLD 
End

...strange...I must have do something wrong. Any idea???

Thanks
Pierre

This line should be deleted:
Normal-Tangential Velocity = Logical True
Solved.
