System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 2080 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.40

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-02-04 00:22, hash: d30320b4f5
Worked: None. I tried the LTS release, doesn't work either. Tried opening in Blender 2.77a, but it crashes.

Short description of error

In the attached .blend file, just press "bind" on the "Mesh deform" modifier. It does nothing. The "Tube" mesh does not bind to the "Tube Deform" mesh.
You can check whether the Bind was successful by moving the Hook empty objects.
Mesh deform works when a newly added cube is used as the deforming mesh, but doesn't work once it is scaled to embrace the "Tube" model in edit mode.
Hope it isn't me that is doing something wrong. Good luck!

I can reproduce this on the latest 2.92.0 Beta, branch: master, commit date: 2021-02-10 00:16, hash: f617782fc1.

Increase the precision to 7 to make this work.

While the implementation could be improved to better adapt automatically, the issue is that this is a long thin mesh. Mesh deform involves a grid solver and that grid resolution at 6 or lower is not enough to capture the long thin shape.

Alright. Thank you.
For the time being, maybe an error message would be a good idea if it detects that no vertexes are affected?
