Trouble running paraFoam in cavity tutorial
 

Hello,

I am new to OpenFOAM. I recently installed OpenFOAM 2.3.0 on a Ubuntu 14.04 OS, and am trying to go through the first standard "cavity" case file.

In attempting to visualize the mesh in ParaView, I was able to open the GUI by typing "paraFoam" in the terminal under the case directory. However, the following errors popped up, and I was not able to visualize the mesh:

If anyone has encountered this before or has a way to fix it, I would be grateful. I am new to programming and to working with opensource software, so please elaborate...

Thank you!

Hi,

it seems you've forgotten to generate mesh with blockMesh utility.

Thank you alexeym, looks like I overlooked that important step...

I appreciate you posting the reply so quickly!
