Periodic BC Rotate
Posted: 07 Jul 2014, 15:16
Hi,
I have this geometry (see image) and need to enforce a periodic boundary (between inlet and outlet). There is a 30 degrees rotation along the z axis (vertical, out of image) to bring the inlet back onto the outlet. The problem is 3d.
How do I enforce this poeriodic bc in my sif files? what I tried did not work. Here is my attempt:
I have tried rad and degrees.
Any help?
Thanks
Denis

Code: Select all
! Periodic BC
Boundary Condition 4
Name = "ice outlet"
Target Boundaries = 5
Periodic BC = 6
Periodic BC Rotate(3) = Real 0.0 0.0 -30
Periodic BC Velocity 1 = Logical True
Periodic BC Velocity 2 = Logical True
Periodic BC Velocity 3 = Logical True
Periodic BC Pressure = Logical True
End
! Periodic BC
Boundary Condition 6
Name = "ice inlet"
Target Boundaries = 3
End
Any help?
Thanks
