Hi, I am trying to simulate capillary rise in a channel. My channel consists of a small channel inside the bigger channel (see the figure).


As you can see the surface contact angle at the top and bottom walls of the channel is showing correctly but when the fluid is passing through the smaller channel, the wall effect is not showing.

I have given the same wall condition to the smaller channel and bigger channel.

Can someone tell me what could be going wrong?

Hi Gaurav,

I am working on a similar problem and have some issues setting up the boundary conditions. Did you managed to solve the problem and if so could you share you 0 file?
