I would like to modify the values in the colour legend so that they are a scale of 1e-3 and evenly distributed. I mean that the scale would be 0.12e-3, 0.1e-3, 0.08e-3 etc instead of the current legend. Is there any way to do this in Paraview?

Here is picture of the current plot

I had to reinstall OF-1.6. I've tried testing the cavity case using FoamToVTK in Paraview. No mesh appears first, but when I then click on the mesh and start scrolling my mouse around the mesh flashes in appearance. When I remove the click it reverts to no mesh as previously.
Is it a case of reinstalling Paraview and trying the case again? Also how do I do reinstall it without removing OF. ]]> OpenFOAM Post-Processing smillion http://www.cfd-online.com/Forums/openfoam-post-processing/79826-paraview-opens-but-image-keeps-flashing.html Pe tool error http://www.cfd-online.com/Forums/openfoam-post-processing/79773-pe-tool-error.html Fri, 03 Sep 2010 09:03:51 GMT Hi, I would like to use the Pe tool, I use pisoFoam solver with kOmegaSST turbulence model.

I am looking for a way to extract ptot average over a surface for each timestep.

Is it possible somehow to do this in OF 1.5-dev with the functions in controlDict while the simulation is running or do I need to save all necessary timesteps and use the ptot utility afterwards?

Hi foamers,

For some reasons, I need to compute the laplacian of a scalar, which is the divergency of the gradient of this scalar, as a post-processing.

Thanks to foamCalc tool, I found the div operator and the magGrad operator ; but I'm struggling to find the grad operator. I suppose that if foamCalc can compute magGrad, ha can as well compute and write grad, but my poor knowledge in coding doesn't help me here.

Does anyone know how to write the gradient of a scalar as a post-processing ?

The answer may be simple, but as for now I didn't find it.

Hi foamers

i am working on supersonicflow over a Backward facing step (using sonicFoam solver in 1.6). i want to validate the results.

i have done analysis and compared the results but the results did not match that good.

i have taken care of all the boundary conditions and mesh etc.

i expect the problem could be meshing near the wall (i mean not properly capturing the turbulent effects near the wall). so finally i thought to calculate y plus near the wall.

but the strange thing is i am unable to calculate the flow properties at the first grid point near the wall and even the distance between wall to the first grid point.

so anyone help me to calculate the above

The reason is that I run big transient cases for a long time and the actual time series is of interest so I need to save often, thus taking a lot of disk space. Once the run is finished I mainly work with the Fieldview files but would still like to be able to go back to OpenFOAM to do postprocessing or restart the case. Being able to delete all time directories and only keep the FV-files would save disk space.

A test case appeared to run without problems but despite reading several user guides I don't know how to view the results in paraview.

I have installed the two dll files as requested by paraview.
I have tried paraview 3.4 (that is packaged with openfoam). Creating and opening a blank file in the working directory with a .openfoam extension does not appear to allow any results to be displayed.

Installing the latest version of paraview (v3.8) with a .foam file does not get me any further.

I compiled FOAM and ParaFoam from the git repository (1.7.x) and everything works as expected except for pvserver.

I should be able to execute "mpirun -np 8 pvserver" to start a ParaView server on a single computer with multiple CPUs (8). When I do that, however, I get 8 lines, the first of which indicates the pvserver has been started:

Listen on port: 11111
Waiting for client.....

But the following 7 lines repeat:

Listen on port: 11111
ERROR: In /home/user/OpenFOAM/ThirdParty-1.7.x/paraview-3.8.0/Servers/Common/vtkProcessModuleConnectionmanager.cxx, line 191
vtkProcessModuleConnectionManager : Failed to set up server socket.

I've found sources online that tell me that exact error message is produced when the port chosen (11111) is being used by another program. So "mpirun -np 8 pvserver" is actually launching 8 instances of pvserver, the first of which successfully grabs port 11111 and the last 7 which spit out errors because port 11111 has already been taken by the first instance.

Has anybody seen behavior like this before, and/or does anybody have any suggestion on how I could fix it? Is there anything special that needs to be done to enable MPI during paraFoam compilation?
