Problem running tutorial
 

I've seen this posted elsewhere, but the solutions don't seem to apply to my case.

I'm running OpenFOAM on Ubuntu in VirtualBox. I followed the instructions to install the Ubuntu Deb pack from the OpenFOAM website: http://www.openfoam.org/download/ubuntu.php

When I run icoFoam -help, I get the usage message as expected.

However I run the tutorial using the sequence
blockMesh
icoFoam
paraFoam

blockMesh and icoFoam run without error,
but paraFoam generates the error message:
OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU
OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU

paraview opens and displays a grey 3D block.

Thanks so much for your help

Hello,

have you changed the settings in Paraview, that it displays the solution? From SolidColor to one of your variables?

Hi Treima
 

I haven't changed any of the settings in Paraview,
I'm new to all of the software I'm using here and wouldn't have the first clue how.

Play a little bit around with the parameters in Paraview or do some online research, I think that will help you a lot.

For your special case, have a look at the description of the tutorial: http://www.openfoam.org/docs/user/cavity.php#x5-40002.1

Thanks again,
This helped me understand how to view results in Paraview, but when I try to look at a variable like pressure, I still only see a blank surface.
I noticed while looking at the output of icoFoam, I see a time step continuity error at several iterations.

Greetings to all!

I'm too tired right now to go through my blog post Related issues to ParaView with OpenFOAM - Fixes and solutions
Check the links provided there and do let us know if one of them is of any help!

Good luck!

Is 3D acceleration turned on in your VB? I think I was getting a similar error until I disabled it... Could be wrong though
