CFD Online Discussion Forums - [OpenFOAM] "Data Range Too Small To Render" Cavity Tutorial

Hello, I am following the cavity tutorial provided from sourceforge.

I have not run into any problems executing the case in the termal, but when I go to view pressure contours in paraview I get a solid rendering instead of colour gradients representing the pressure. In playing around with the Color Map Editor I see a message stating "Data Range Too Small to Render."

I did not get any obvious error messages when I ran the case, but I will post the terminal i/o. Unfortunately, I am learning this on my own and dont have access to professors (or anyone for that matter) who is experienced with the software. Any help is appreciated

change directory

Code:

=> cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity

execute the mesh

Code:

=> blockMesh

run the case

Code:

=> icoFoam

output at last iteration

Code:

any idea what is up?
