System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 516.59
CPU: Intel Core i7-7800X
RAM: 64 GB

Blender Version
Broken: version: 3.2.1, branch: master, commit date: 2022-07-05 15:44, hash: a2d59b2dac
Worked: unsure

Short description of error
Whatever you put in surface tension parameter of Mantaflow liquid domain, it has no effect on final result at all.

Exact steps for others to reproduce the error
Setup simple yet detailed enough liquid simulation with Mantaflow, type any number in surface tension parameter, bake sim, observe result.
Repeat changing surface tension parameter to any other number - no changes at all.

I hoped this would help me get more "sheeting" effect in my project, the official docs are very laconic abouth this parameter, I failed to google any info about it, it gives me many about FLIP Fluids Addon. But what about Mantaflow?mantafluid_01.blend
