Hi! I am very new in Star CCM+ and I am developing a simulation of discrete element particles to generate a packed bed in a tubular geometry. I would like to know how data is imported from a table in Star Ccm + that contains the positions of the discrete particles in a new geometry (in my case the particles are spherical). I have already done the DEM simulation and I already have the table (XYZ Table) with the positions of the particles, but I do not know how to integrate them into a new simulation. I understand that it can be done by Java Macros, however I am really a beginner at Star Ccm +.

Greetings.

you can use the table injector method using a table format as documented here in the help Simulating Physics > Multiphase Flow > Using the Lagrangian Multiphase Model > Working with Injectors > Using Injection Tables

however you say you have new geometry so you need to be pretty careful that you dont break any dem rules about injection as explained here Simulating Physics > Multiphase Flow > Using the Discrete Element Method > Defining Injectors in the Discrete Element Method

this is why it is generally better to use something like the random injector and let the particles settle properly under gravity

But right now my step is about include the dem particles (already have done the simulation of settle particles) into a new geometry, I mean. I need a new tubular geomety + the positions (XYZ) of the particles as a new part geometry. That is the issue I can't resolve.

hello guys


I have the same problem. I did the DEM simulation and I need generate a mesh with the spheres with the position that them had on DEM.

Is it possible, with StarCCM+?
