Example Breaking of Dam
 
Hello. I need help. In the example of the breaking of a dam, on the line boxTo Cell.

box (0 0 -1) (0.1461 0,292 1);

Why zmin is -1 and zmax is 1?. Whereas the geometry of the problem defined in the point z 0 and 0.1. I do not understand.

I hope you can help me. Thanks.

Size of box merged with cells
 
Hi

The size of the box does not matter when it's bigger than your domain. All cells in z-direction are between -1 and 1 so all are set to alpha1 = 1.

Regards

Fabian

Thanks Fabian. Then I can define zmin = 0 and zmax = 1, and I get the same answer that zmin = -1 and zmax = 1.
