|Summary||0000639: Wall distance across non-matching AMI|
|Description||Wall distance across non-matching AMI is not correct. Not sure if it's a bug or just not supported.|
|Steps To Reproduce||Test case (5 MB) can be provided if requested.|

It should work, there is no distinction between 1:1 matching and non-1:1 matching in AMI, they all are just using an interpolated value (based on the area overlap).
What are your weights min and max and average?
Can you set up a tiny case that demonstrates the problem?
The problem is that the functions to make the nearest wall point relative are not reciprocal so accumulate errors.
I'll push a workaround 5ecafe8a5e035a55781a3b62a7870b585daaf0ed which for collocated AMI does not use these functions and will have a think about how to solve it in general.
||More accurate wall distance fields may be obtained using the Poisson or advectionDiffusion methods which will operate across AMIs in the same manner as solving for any FV field.|
