Obstacle are somewhere wrong implemented

[LinhWuerzburger]

residuum of Jacobi solver raises infinitely.

t=0.2 of FlowAroundCube example

[LinhWuerzburger]

something is still wrong. needs some more investigation

[LinhWuerzburger]

changing the obstacle has an effect.. somehow.

[LinhWuerzburger]

it may be a problem of a combination of multigrid and obstacles, can be investigated by setting the multigrid level to 1

[LinhWuerzburger]

create a test scenario where a wall is blocking the flow from the left side. no flow on the right side

• IC with flow left from the obstacle
• no background flow ?
• inflow through BC ?
