Hello from Sanket
I am new OpenFOAM User. I want to make a hollow rotor inside block. I made a geometry which in BlockMeshDict file.( Rsmall=1, Rbig= 3 and Block is 10*10)

Could someone explain me? (If someone has answered then give me the link)
I got an error like: Creating block mesh topology
--> FOAM Warning :
From function Foam:olyMesh:olyMesh(const Foam::IOobject&amp;, const Foam::Xfer<foam::field<foam::vector<double> &gt; &gt;&amp;, const cellShapeList&amp;, const faceListList&amp;, const wordList&amp;, const Foam::PtrList<foam::dictionary>&amp;, const Foam::word&amp;, const Foam::word&amp;, bool)
