Question about the case cavity
 

Hi, I'm a beginner of Openfoam. My professor just well installed it on my mac for me. Following the UserGuide of Wikiopenfoam, I did
'
mkdir -p $FOAM RUN
cp -r $FOAM TUTORIALS $FOAM RUN
cd $FOAM RUN/tutorials/incompressible/icoFoam/cavity
'
Then when I tried 'blockMesh .cavity', it resulted in 'Wrong number of arguments, expected 0 found 1'.
When I tried 'blockMesh . cavity', it resulted in 'Wrong number of arguments, expected 0 found 2'.
When I tried 'blockMesh.cavtiy', ir resulted in 'command not found'.

So could you tell me please how to do this Mesh generation? Thank you very much.

Just run "blockMesh"
