Summary0000937: pipeCyclic (60°) - AMI weights go down to 0
DescriptionI took the pipeCyclic case, and made the following changes:
- a geometry of 60° instead of 90°
- a mesh generated with snappyHexMesh
- a createPatchDict to generate the AMIs.

The mesh is OK (checkMesh gives OK, and the two AMIs don't seem to have any non-overlap regions), but after running createPatch I still get weights that go down to zero.
Steps To ReproduceRun the Allrun script.
Additional InformationThe same setup for a 90° geometry (only changing the stl files in triSurface) works perfectly (all weights =1).
TagsNo tags attached.

I ran through your steps (without -overwrite) but cannot repeat your problem.

I have snappyHexMesh in 1 and 2 and then the cyclicAMI in time 3. E.g.

    foamToVTK -latestTime

(since checkMesh does not trigger building the AMI weights) prints:

AMI: Creating addressing and weights between 760 source faces and 720 target faces
AMI: Patch source weights min/max/average = 0.999999, 1, 1
AMI: Patch target weights min/max/average = 0.999279, 1, 0.999997

and simpleFoam also runs ok.

I run the exact same steps, and this is what I get:

AMI: Creating addressing and weights between 760 source faces and 720 target faces
AMI: 1 non-overlap faces identified
AMI: Patch source weights min/max/average = 0, 1, 0.650199
AMI: Patch target weights min/max/average = 0, 1, 0.657206

What could possibly be the problem?

I ran with latest 22x:

Build : 2.2.x-57d2da44f116

your ./Allrun script runs fine and simpleFoam does

AMI: Creating addressing and weights between 760 source faces and 720 target faces
AMI: Patch source weights min/max/average = 0.999999, 1, 1
AMI: Patch target weights min/max/average = 0.999279, 1, 0.999997

It works now with the latest 2.2x version, thank you.
