Worked: (newest version of Blender that worked as expected)

Short description of error
The mesh is not generated in areas that are in contact with the walls of the domain.

Exact steps for others to reproduce the error

mantaflow_test_mesh.zip87 KBDownload

  1. Open file
  2. Bake the liquid
  3. Set Physics properties > Mesh > Upres Factor = 6
  4. Bake the mesh

Particles don't fit in mesh. This doesn't happen if Physics properties > Mesh > Upres Factor = 1

I can not confirm this in older or newer Blender version.

Please click on File > Defaults > Load Factory Settings and check if that will resolve this issue. Just make sure you re-bake particles and mesh.

I think I can see this effect with default cube afrer running quick liquid, but I am not sure if this is bug.

Edit after quich testing It seems that increasing Mesh Upres Factor will "offset" the mesh.
