CFDEM®coupling - User Forum

Hello All,

I am running CFDEM simulations of internally heated particles, with an external code determining each particles heatSource value. Currently I am able to run a single iteration, steady-state, case where by

Hi CFDEM,

Hello Users,

I am a new user for CFDEM coupling and I am conducting my thesis modelling high efficiency stairmand cyclone. I am using pisoFoam solver at the part of CFD and snappyHexmesh tool for building cfd mesh this part it goes well without any issue. when I came to the part of parallelization I faced the following error which is attached below..
I am stuck at this point I would really appreciate any help to be able to proceed with my thesis.

Regards.

Hi guys!

Did anyone know how to correctly set up the wear model in CFDEM coupling?
I am trying to set up, but the results looks strange.
and where to find the wear model in Liggghts?

The result is shown below.

Hi all,

Hi, I am apparently a new user of CFDEM. I have two issues:

#1
I wanted to insert a large number of particles 100000, with radius 0.0005 in cgs unit system and wanted to insert few at some interval. Therefore, I used the following in my init script

Dear All,

To study the cfdemSolverPisoSTM tutorial, as I only decrease the number of particles in the bed from 1005 from 500. the error comes after resetting data from restart file, as

Hi, I'm the beginner for using "cfdemSolverIB", and I want to know changing 'density' of fluid phase.
(I'm using the source code version (3.5.0), not the workbench version.)
In case of 'non-resolved CFD-DEM' (such as cfdemSolverPIso, ...), the 'rho' file is included in the '0' folder in CFD.
However, there is no data for density of fluid phase in the tutorial 'twospheresGlowinski'.

How can I change the density of fluid phase in "cfdemSolverIB"??
Thank you

Hwang
