ÔÇ£Failed to match periodic faceÔÇØ most likely due to the periodic BCs do not see the periodicity, eg, left and right are not the same. So before fixing other issues, please make sure it is periodic as suggested previously. I also would suggest that you disable all the spheres, and then enable them one by one, and just do meshing without actual simulation and see if the mesh can be generated successfully and which sphere causes this issue. Once identified then we can try to find a solution.
