Post Processing

Hi everyone

I simulated settling of particles in a cylinder. But whenever I read the dump file, I get to display the bounding box only. How can I display the actual cylinder wall as shown in the examples/tutorials.

Hi all,
as written in the topic i downloaded plugins from https://github.com/richti83/ParaView_Reader_for_LIGGGHTS/tree/master/pre... for paraview 4.3.1 64bit . I pick the 3 one from the folder 4.3.1 and the last 2 ( binary reader and rigid reader) from 4.3.0 folder. When I open the .bin file from the chute_wear test paraview suddenly crashes after the "Apply" button.

Any ideas/suggestions ??
Thanks

I am performing simulations where particle rotations are important and would like to visualize particle rotations while post processing.

LIGGGHTS can output the angular velocities (i.e., omegax, omegay, omegaz) easily enough via a dump file. However, I would like to compute the actual angle of rotation from the starting condition. I suppose I just need to perform a time integration and create a new field but thought I'd check if this has already been done.

Has anyone else done this?

Thanks,

Hi All,

I have just installed Paraview, LIGGGHTS and lpp as per guides on this site. I then ran the movingMesh example.

When I try to convert my dump.movingMesh files to VTK using the following code:

d=dump("post/dump.movingMesh.*")
v=vtk(d)
v.manyGran()

after the first line I get the following error message:

luke@Simulation:~/LIGGGHTS/LIGGGHTS-PUBLIC/examples/LIGGGHTS/Tutorials_public/movingMeshGran$ d=dump("post/dump.movingMesh.*")
bash: syntax error near unexpected token `('

hello every one
i simulate a silo and run the programe ,but i dont know why take the plot of presure in wall.please help me.
thanks alot.

hi all
i simulated bin flow and run the program ,but i dont know how to calculate discharge mass flow.please help me.
thanks

Hello all,

I have two different type of particles (of different radius) in my simulation. I want to give different radius for two different type of particles.
I am unable to select the type in paraview. Can some one please suggest how can i do it?

Many thanks,

Narendra

Hi,

I did the example of tetraeder mesh in LIGGGHTS and simulated the results in paraview. After using the point sprite plugin, I found the packing to have some space in between the particles. What should I do to obtain a packing with max no of particles in the volume?

I am attaching 2 images of the result obtained in paraview.

Hello. I've found that sometimes when reading in paraview I got the following Warning:

Generic Warning: In /Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release-Python27/paraview/src/paraview/VTK/IO/Legacy/vtkDataReader.cxx, line 1359
Error reading ascii data. Possible mismatch of datasize with declaration.

When this occurs, only force values are loaded, no velocity, no radius, etc.

Dear community, I'm proud to present the first prototype of a GUI for LIGGGHTS(R) running on Windows(R):

This is a pure hobby project, but I can not give it away for free. This is why I started a crowdfunding project at http://igg.me/at/liggghts-launcher .
When I get enough Backers, I'll add some fancy improvements like syntax highlighting and a OpenGL render view based on ParaView API.
