hi everyone,
I am new user of cfdem. Can anyone tell me how to open paraview through terminal for cfdem result analysis? for openfoam the command is ' paraFoam' but i dont know about cfdem.

Sorry... I already solve my problem.. I just write python -i pizza.py in the src folder..

Hi, I´m having an error and I don´t know what to do.
In the past I have ran and used the pizza tool over a lots of dump files, but now I can´t use it.

usuarioubuntu@SAN1496UBU:~$ python -i /'/home/usuarioubuntu/my liggghts/gran_pizza_17Aug10/src/pizza.py'
Pizza.py (1 Oct 2006), a toolkit written in Python

Hi,
Is it possible to dump snapshots in a format which can be read by EnSight? Or, is there a way to convert them into ensight format by pizza?
Any clue will be appreciated.
Thanks
Ram

Hi!
I'm having a case with 70-80 000 particles (2 types) and creating VTK-files with pizza takes ages. Is there any way to speed it up? Or is the only way to run the simulation again and drop the dump frequency?

Thanks,

Timo

Hi, all

How to use the legend colour to represent the velocity of the particles?
I see all the liggghts examples have this feature, but I donot how to do so.

cheers

Hi!

I am trying to run pizza.py on ubuntu 11.04 (gran_pizza_17Aug10 version) I am getting the following error:

Loading tools ...
gl tool did not load:
No module named OpenGL.Tk

so, I installed python-opengl using SPM which gave the following error:

No handlers could be found for logger "OpenGL.Tk"
gl tool did not load:
couldn't load file "/usr/lib/libTogl.so.1.7": /usr/lib/libTogl.so.1.7: undefined symbol: tclStubsPtr

Please help!

P:S: I have already installed python-numeric, python-numpy

Hi Everybody,

I'm new with liggghts and I have some problem to get VTK data from dump file.
I checked everything and I think to have installed all I need.

Thanks a lot,

Nic.

hi, all

Hi All,
When opening vtk_out0000.vtk
and CFD_0.vtk with paraview for
the ErgunMPI CFDEM test case displays
the CFD data in a large scale and the
DEM data reduces to a red dot. How can
I view the particles and the CFD data in
the same display ?
Any output is welcome.
Alex
