Post Processing

I tried to use the liggghts reader Plugin for Paraview to get the animation results, but I can only get the result at initial step, no matter how I change the time in the box. What wrong with me?

While running the lpp dump file for post processing. I am getting the following error:

____@___:~/LIGGGHTS-PUBLIC/examples/LIGGGHTS/Tutorials_public/conveyor/post$ lpp dump*.conveyor --chunksize=1 --cpunum=1

starting LIGGGHTS memory optimized parallel post processing
chunksize: 1 --> 1 files are processed per chunk. If you run out of memory reduce chunksize.
Working with 1 processes...
calculating chunks 1 - 1 of 350
aborting due to errors: [Errno 13] Permission denied: 'conveyor100000_boundingBox.vtk'

I am trying to convert my granular dump files into vtk with LPP.

When I used pizza before I would type:

d=dump("dump*.gran")
v=vtk(d)
v.manyGran()

With LPP, the d=dump("dump*.gran") works, but when I type v=vtk(d) I get an error.

What am I doing wrong?

Thank you

The link to download pizza seems to have been removed from the download section. I downloaded the one from Sandia, but it does not have v.manyGran().

I also tried to download LPP using git , but I got an error message:

g1@G1-Guerrilla:~$ git clone git@github.com:CFDEMproject/LPP.git
Cloning into 'LPP'...
Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Can some one help me with this?

Thank you,

Kirk

I am use LIGGGHTS under windows platform, could someone tell me how to view the results? I tried Paraview and VMD, but both don't work well. thanks in advance.

please move if this question is in the wrong section.

I wanted to know if the movies/pictures that are used in the "LIGGGHTS features" page are all (or mostly) done with PARAVIEW.

Dear all,

Hi,

I read in a post "contact force" (node/1511) how to output contact forces particle-wall. I would like to know: is there any way to read that info with paraview?

I added to my input script:
compute fc all pair/gran/local id pos force
dump forcedump all local 500 post/dump.fuerza c_fc[1] c_fc[2] c_fc[3] c_fc[4] c_fc[5] c_fc[6] c_fc[7] c_fc[8] c_fc[9] &
c_fc[10] c_fc[11] c_fc[12]

I've just got one file with info (see the attached) and paraview can not load it. I think it might be a problem with the way I use pizza, I just did it as always:

Hi, All:

I now have a simulation results of 1 million particles, the dump file is very large and for paraview it is very slow even just to open a single timestep file (around 0.5G per dumpfile XXX.vtk), does anyone have the experience to visualize such kind of large dataset? Is off-screen parallel rendering the best option for animate the particles under such kind of circumstances?

Thanks a lot!

For the tutorial case: packedBedTemp, I guess, my test run was successful.

last lines of log_run_parallel_cfdemsolver_pisoscalar: looks like

"ExecutionTime = 57.44 s ClockTime = 59 s
End
Finalizing parallel run"

In case folder, I only see a dummy file in DEM folder.

I am wondering how to postprocess or view the result.

thanks
