I have to impose tangencial force on my interface between air and gaz
to simulate Surface Tension. (Watch out the pics, (it's interface between red and blue))

I have 2 physics seperated between an interface. I must use Boussinesq for this case so => I don't want to use VOF because it doesn't works on my case!

If anyone can tell me how I can do this it will be very helpful.

Thanks for reading and Have a Nice day!

VOF is the correct model for doing this. You've posted about this case several times now, but never seem to go into much detail as to why VOF didn't work. You should do some work as to why that happens as opposed to fudging things with specified forces.
