Hello everyone,

I have this error when running snappyHexMesh:

--> FOAM FATAL IO ERROR:
keyword refinementRegions is undefined in dictionary "/home/sylvie/OpenFOAM/sylvie-v1612+/run/projetfinalsimplefoammanuel/system/snappyHexMeshDict.castellatedMeshControls"

Here is my snappyHexMeshDict where there is a line with refinementRegions !...:

I don't understand why... Any help ?

Thanks in advance

In fact I deleted all the files and did again and now it's ok. But when I go into parafoam, when i want to select the buildings and the relief and the chimney (so meshed with snapppyHexMesh), they just disappear and only the box (so meshed with blockmesh) remains (with inlet, oulet etc...) I don't understand at all....
