Sorry, very late.
In leisure time, I check this out again, and find this "velocity getting slow" thing is not incurred by the nu. I attached an image using the new nu field. In this solver I make...

hi olivier,
There are four functions about nu, nuf, mu, muf in the code of twoPhaseMixture.C, I change the function regarding "nuf" and "muf", I think its the viscosity in the face which make the...

Hi,
About this, my opinion is this: look at this image. the four cells in the middle is some kind viscious liquid which viscosity is 1000, the other cells' viscosity is 1, By openfoam's code:

Hi olivier,
Thats a light from the dark, Thanks. But what is Cie?
Looks like this could explain the high viscosity liquid is droping more slowly, for example: if the nu1 is 500, nu2 is 1,...

I check the voscosity model in OpenFOAM, for example CrossPowerLaw code:
return (nu0_ - nuInf_)/(scalar(1) + pow(m_*strainRate(), n_)) + nuInf_;
Does it mean it do not consider the two phase...

interFoam, wierd nu.
Hi,
In interFoam,I usually simulate a system of non-newtonian fluid. So I just make a test,in tutorial dambreak, I set the lower part of the mesh is all of fluid, and the higher part is air....
