Capillary effect
Hello everyone!!

I would like to represent the capillary effects with FLOW 3d but I'm currently blocked.. I am using the SI unit and I modeled a simple tank. I want to see the evolution of the free surface when gravity is reduced in cylinder tank.

for the fluid, I apply to it a low gravity , for example : 0.000981 m/s^2 and a surface tension coefficient of 0.014 and the fluid is incompressible and laminar.

However, the effects of cappilarity do not appear in this low gravity.

Someone know why ?

Thank you very much
