Hi, very new to paraview and LIGGGHTS. I need help urgently for my dissertation. In the most simple form, could somebody please tell me how i can calculate mass flow rate of particles leaving a hopper (simulation was done on liggghts) I’ve seen tutorials on this but am unable to find one that i understand as i am very new to this. The version i am using is paraview 5.0.1. Thanks in advance.
Welcome to ParaView!
I’m afraid you haven’t provided enough information to help you. Could you post what you have been able to do so far, e.g. read in a file from LIGGGHTS, visualize particles, and so on?
Hi, thank you for your reply. Essentially I built my own hopper within Creo and exported it as an .stl file into a script on liggghts. The script runs perfectly fine and models around 5000 particles of radius 0.0015. I’ve been able to visualise it in paraview, everything seems to be working fine. I set it to 3D glyphs, radius 0.0015 and changed the colouring to v magnitude (which i assume is velocity) I’ve also attempted to put a slice at coordinates 0, 0, 0 (on Z plane) at the exit hole of the hopper. For my work I have been told to simulate mass discharge and change various processing parameters (such as friction coefficient/ particle size) within the liggghts script to see how they affect the mass flow rate. Ive seen a few tutorials for flow rate on the forums but my knowledge is very limited as i have never used this type of software before.
Thanks for any help you can provide,
I’m hoping for a response to this question as well.
I have LIGGGHTS vtk dataset, struggling with the workflow on how to measure particle flow rate through a surface or volume.
Visualisation of particles works fine, Can see velocity, animate the simulation. Managed to get temporal particle streaming to work.
Visualisation of stress and wear on meshes is all good.
I have experimented with slices, surface flow and integration but struggle to get results.
