Issues with cyclicPeriodicAMI patch type: source and target faces.

Hi,

There is a tutorial - oscillatingInletPeriodicAMI2D (v1712) which uses the cyclicPeriodicAMI patch type.

If this tutorial is run as it is - there are no issues.

If you do a checkMesh -constant -allTopology -allGeometry on this case - there are no issues.

In this case (original tutorial) , it is found that the number of source faces are less than the target faces.

However, if I refine the mesh on the left block (I increased the number of points from 40 to 100 on the left block (in the Y direction) - the points are now greater than 96 (points in the Y direction on the right block) ) , such that the source faces becomes more than the target faces, the above checkMesh command fails.

Please refer to the attached file.

Do you have a solution for this, or is this a bug?
