Hi Mathias,

Sorry, I don’t understand what means “too fee fluid nodes”, >_<

We want to build a model of a two-phase flow(liquid and air) in porous media. In porous media the situation of fluid with one layer lattice is usual. So it’s easy to lead no converge.

Not converge
. . .
2 1 2
2 1 2
2 1 2
. . .

Does it mean we must make sure there are fluid with at least two layer lattice in whole geometry. Really need the help of your team! Thank you!

Regards,
Kai Lin

I correct the distribution of material number. Could you please tell me why? Thx!

Later part is not shown properly.

We set the parameters with contact angele 46 degree.
Fluid can’t wet over the block

Thanks for your kind reply with email yesterday! Finally I can speak at the forum ^_^
