CFDEM®coupling - User Forum

hi everyone,
Now ,i want to add fvOption file to cfdemIB. First, I called in cfdemIB.C file and then added -lfvoptions to option file. After that, I went to compile my solver, but the error was reported.As follows:
cfdemSolverIB.C:44:29:fatal errror:fvOptions.H:No such file or directory
#include "fvOptions.H"

I have been scouring the internet for an answer to this question and I can't seem to find anyone who has truly dissected it so I'll post the question here. If anyone knows of a paper or forum post that already addresses the following concerns that would, of course, be really helpful.

I was modelling a packed bed using cfdem solverib so that i could get the resolved velocity field. But i have noticed that the pressure residuals after decreasing start to increase and never converge. Can anyone help me solve this problem? The residuals decrease to about 0.2 and then slowly starts increasing. I have tried using relaxation factors but the same thing happens. And the final pressure drop i obtain for the bed after many iterations is not accurate compared to the ergun equation.

Hi All,
My simulation of a heated packed bed is progressing, however I have come across another difference between my CFDEM results and my past results using starccm+. The pressure drop across the pebble bed is expected to be ~550Pa, which is what the experimental results show, as well as mine and another authors simulation results in the past.

Dear All,
I am trying to simulate a small section of the dilute gas-particle flow in a riser.
The boundary conditions for the particle phase were set as periodic boundary in the z direction (boundary m m p). The solids volume fraction is 0.018.
The boundary conditions of incompressible gas phase are: uniform inlet boundary at the bottom (0 0 0.0925) and pressure outlet boundary at the top (zeroGradient). The other boundaries were set as no slip walls.
The solver is cfdemSolverPiso.

Dear community,
I try to install CFDEM latest version and meet problems...See below
Could somebody help me to fix problem? I usem Ubuntu 18.

fura@fura-VirtualBox:~$ cfdemSysTest

Hi all,

I have been trying to implement a case similar to the packedBedTemp cfdemSolverPisoScalar example case where hot particles are cooled by a flowing continuous phase. For my case I will not know the temperature of the particles, but instead the power (in Watts) of each particle so I am thinking I will need to use the heatSource model instead of the Temperature model within heat/gran. I have read the brief discussion of it in the user manual, but I am having trouble replicating results I have gotten through commercial codes.

Hi guys,

Hi, guys.

There is a problem restarting the liggghts file.

Specifically, I can not restart my simulation about the latest time using the file "DEM/post/restart/liggghts.restartCFDEM" after my computer suddenly turned off.

This is the second case.

First, the restartCFDEM file exists but the file size is 0KB.

The second file exists normally. However, if I execute "parCFDDEMrun.sh", it will not proceed in the step of reading the restart file as below.

Dear All,

Has anyone successfully installed CFDEM®coupling (version 3.7.0 or 3.8.0) on macOS 10.13 High Sierra, or on macOS 10.14 Mojave ?

Does CFDEM®coupling work correctly on the latest releases of macOS ? Any comment ?

Regards,
Limone
