Hi watashiwa,


I am not sure what is causing your error, maybe someone else here has a better idea, but did you just install OpenFOAM or did you compile it too?

Lee,


You can put your stl file (I think it should be a ASCII stl) in the "constant/triSurface" directory.
You then need to open the "system/snappyHexMeshDict" file and find where the stl file...

Hi Lee,

snappyHexMesh cannot find the fvSolution file, did you copy the motorbike case directly from $FOAM_TUTORIALS without making any changes to it?

Stark22,

I'm not sure what the motorbike.OpenFOAM file is, I suspect it is created by paraFoam. I don't use paraFoam, I use 'foamToVTK' and then open the VTK file in 'paraview'.

So you could...

Stark22,

It sounds as if it ran fine. The bike is very small relative to the size of the flow domain, so as far as I can remember you set the view to wireframe and zoom in very close to the centre...

At the top of the snappyHexMeshDict,
you can set the layers feature to on or off.
