Holes are detected in wrong places by the overset algorithm in ``twoSimpleRotors`` tutorial

Summary

The overset algorithm detects the wrong cellType. Basically, it marks some cells as holes when the interpolated cells are near the wall.

Steps to reproduce

Run the twoSimpleRotors tutorial for few time steps and visualize the cellType in paraview.

Example case

Run the twoSimpleRotors there are no modifications needed to produce this issue.

What is the current bug behaviour?

Holes are detected in wrong places which leads to zero velocity.

What is the expected correct behavior?

It should be as shown in the user guide

Relevant logs and/or images

Here are a collection of six snapshots for cellType field and two for the velocity field;

  • t1 test1
  • t2 test2
  • t3 test3
  • t3, velocity field test3_U
  • t4 test4
  • t5 test5
  • t6 test6
  • t6, velocity field test6_U

Environment information

  • OpenFOAM version : v1906
  • Operating system : ubuntu 18.04LTS WSL on Win10
  • Hardware info :
  • Compiler : gcc

Possible fixes

I'm not sure but it seems that this issue didn't exist for the version you used to produce the video attached above.
