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? Mattijs |

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. |
