Hi Dear FOAMers
In the tutorials. In the case "capillaryRise". For boundary condition for walls. What does "limit gradient;" means?
"
walls
{
type constantAlphaContactAngle;
theta0 45;
limit gradient;
value uniform 0;
}
"
Any help will be appreciated.
Best regards

Ata

You already posted in another thread that contains the answer to your question: how to specify wall contact angle for compressibleInterFoam?

Did you forget?
