About the 1st Example and Paraview
 

Hi,
I am doing the 1st example of the tutorial: the incompressible cavity flow. I had typied:

mkdir -p $FOAM_RUN
cp -r $FOAM_TUTORIALS $FOAM_RUN
cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity
blockMesh

And next, after I typed:

paraFoam

The terminal showed:

OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU
OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU

And the paraview started with nothing having been done...I don't know why as well as what I should do. Actually I am a new Linux User and Foamer.
Appreciate it if there is any help!
Best,

Did you run the icoFoam solver?
It is not mentioned in your steps (but it is in the tutorial)

Thank you for your reminding, anon_a! I works!
Best,
