|
|
*
|
|
* This problem is inspired by groundwater flow. Don't expect it to be
|
|
* realistic, though: For two dimensions, the domain size is 1m times
|
|
* 1m. On the left and right of the domain, no-flow boundaries are
|
|
* used, while at the top and bottom free flow boundaries with a
|
|
* pressure of 2 bar and 1 bar are used. The center of the domain is
|
|
* occupied by a rectangular lens of lower permeability.
