Hi Bruno,

If I perform a translation the velocity profile would not be correct, hence a wrong solution will be obtained. So I tried rotating the outlet flow around the x-axis, and the thing I notice when createPatch is executed, is that I get the following message: Code:

Hi Admir,

Code:
rotationAxis (0 0 1); rotationCentre (6.06e-3 3.5e-3 0); If I understand your idea correctly, what you want is to rotate over X for switching over the geometrical perspective; but you will also need the translation that will move the position from one side to the other, so that the positions are transformed onto the same locations on the other patch. Problem is that such a two or more steps transformation is not possible with the current capabilities that OpenFOAM provides for cyclic patches. As far as I can figure out, there are at least three possible solutions that come to mind:
And I guess that the "cyclicAMI" is useless for your case, given that a 2 step transformation is needed, which isn't available. Best regards, Bruno |
