Hi,

I have to perform a particle tracking in a blood micro vessel network. I have an stl file for the geometry and I build the grid with snappyHexmesh. My grid is OK for the flow but not for the particles :
--> FOAM FATAL ERROR:
No base point for face 1854708, 4(894291 917963 919857 916949), produces a decomposition that has a minimum volume greater than tolerance.


I tried many unsuccessful combination in snappyHexMeshDict which I join here.
Can someone tell me which parameters I have to modify to generate a nice grid?

Thanks

Yannick
