snappy hex mesh error
 
Dear all

I was running the motorbike snappyhexmesh example. After creating the blockmesh using the blockmesh command. I run snappyhexmesh but get the following error

Surface refinement iteration 7

Does anyone know what is wrong ?

thanks

CFT,

Which version of OpenFOAM are you using?

I am using 1.5-dev and the motorBike tutorial runs for me by just blockMesh followed by snappyHexMesh.

I have attached what my snappyHexMeshDict looks like, I assume yours should be the same and if not could be the cause of the problem.

Hope it helps,
Philip
