Hi !

I have tried to make a hole in 3d, I mean like a air bubble in water.
But I have got a strange error message from blockmesh.
What I really try to so is a aircraft in a virtual wind tunnel there the bubble is the aircraft.

Have any one tried to do some thing like this?

Are there any other solutions on this problem?

Maybe there is a solution if you give us some detail on the error message.

Here is the blockMeshDict

As you can see, I have tried to make the inner walls oriented the other way around

The case is a modify /home/rickard/OpenFOAM/rickard-1.5/run/tutorials/icoFoam/cavity

what I try to do. This is done in Gmsh. But I can't find any solution that takes gmsh mesh.
OpenFoam can convert it but only with gmsh1.*.
And I've tried to complie Gmsh2ToFoam but my it dont work with OF 1.5.
