Dear All,

I want to simulate industrial cyclone separators by MPPICFoam too. For that, I draw a cyclone configuration in SolidWork and producted a STL file, Now I should product grids (meshes) by editing blockMeshDict and then snappyHexMesh...

1- How should I change the blockMeshDict file (vertices, blocks, edges, boundary...) of OpenFoam example and then snappyHexMesh?

2- Should I change the dimensions of the industrial cyclone in OpenFoam?

please help me.

Thanks

1. blockMeshDict boundary must cover your entire cyclone, you can reduce the number of cells per rows for more fine mesh
(checkout motorBike case to learn snappyHexMesh)

blockMesh | tee log.blockmesh
snappyHexMesh -overwrite | tee log.snappyHexMesh
checkMesh | tee log.checkMesh

2. usually dimensions are taken in meters, so scale up/down if you want to change
for eg. if you have dimensioned in mm then scale factor is 0.001 (1m = 1000mm)

hope it helps
