![]() The higher overlap area of particles in system is accepted, the lower void fraction can be achieved. For examples, due to external force on boundary, particles will move closer and reduce void fraction. (3) I want to simulate particle contact with respect to different level of overlapping among particles. (2) Can I visualise walls on Paraview? The normal walls created by LIGGGHTS (primitive) seem not be seen on Paraview I think. Is that possible to apply forces on boundary walls and these walls moves inward and compress the ball inside? I know we can apply velocity on the boundary walls but not sure about force on boundary wall. I will compress these balls by external force to make them re-arranged and reduce void fraction. (1) I have a number of ball strings (balls bonded as beam or string) in a certain arrangement (a certain initial void fraction). Due to my very limited knowledge of coding, could you tell me roughly how to compile them to Paraview? Do I need to copy them to src of Paraview and re-compile Paraview again?īy the way, I have some confusions regarding my modelling by LIGGGHTS that would be great to have your advices. ![]() I have downloaded your package including reader-src and pre-compiled folders. It brings remarkable convenience to LIGGGHTS users and possibly other playgrounds which relate to dump files as well. That is a great idea to use dump file directly without converting to VTK. Thank you for your active and great contribution. Very impressive to Christian (User: Richti83) who still keep working and replying on holiday 1st, new year 2015 :). Could anyone give me a hint on my problem? Is there any better solution to convert dump file of gran/local computation to VTK? It must be important for most of simulations to demonstrate interaction forces a mong particles and particle-wall on Paraview, I beliew. I think some users and specliasts in the forum are familar with this routine and handling local dump file to VTK. I have checked my dump file with satified index (pos, id, force), for example a typical segment below Looking into several discussions in terms of this issue, I am enable to have EVTK and dump2forcenew.py ( or dump2force.py by Mark Bentley) routine however the running come out with error:įile ".LIGGGHTS/mylpp/src/dump2forcenew.py", line 74, in To start a new year, I would like to be clarified concerning a solution to convert dump/local output to VTK file.
