[Technical] bubble in blockmesh

SkunkWorks · June 23, 2009, 17:37

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.

Hi!

I'm trying with different node order on the inner face.
look at the picture that I'm made in gmsh to make the work it easier.

And here is the output from bash.

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.
