CFDEM®coupling - User Forum

Hey there,
I have a minor problem with the sedimentation velocity of a particle. The Particle is located on the top of an tube and shall sediment to the ground of the tube. I am have chosen the following parameters in the couplingProperties file:

modelType "A";

forceModels
(
DiFeliceDrag
//SchillerNaumannDrag
//KochHillDrag
//MeiLift
//virtualMassForce
gradPForce
viscForce
Archimedes
);

When running the standard ErgunTestMPI file using 4 processors and by changing the (CFD) commands in parCFDDEMrun.sh to
#- get VTK data from CFD sim
cd $casePath/CFD
#foamToVTK #- serial run of foamToVTK
source $CFDEM_SRC_DIR/lagrangian/cfdemParticle/etc/functions.sh #- include functions
pseudoParallelRun "foamToVTK" $nrPostProcProcessors #- pseudo parallel run of foamToVTK

I only obtain errors.

And when using the default version

Dear all,

I tried to install openfoam 3.0.0 and Liggghts and coupled them to CFDEM-3.0.x. Everything looks fine,only the last step for cfdemTestTUT. At the last step, I tried to do it step by step. Firstly, the turbulent model and BC were changed. Only openfoam was tested and worked normal, then running ./Allrun.sh, but some errors also came out:

Hi everyone,

I tried to install CFDEM (openfoam 3.0.0 with Liggghts, paraview 4.4.0) on ubuntu 15.10 and followed the installing procedure from CFDEM website (http://www.cfdem.com/system/files/githubaccess_public.pdf). Openfoam3.0.0 and Liggghts work. But some errors happened at the CFDEM coupling in the last step by typing: cfdemCompCFDEM.

Hello.

I've been trying to compile CFDEM coupling, but I get the following errors:

Hello,

the latest release of CFDEMcouplng-PUBLIC compiles with several different OF versions.
I personally use 2.4.x (see here: https://github.com/CFDEMproject/CFDEMcoupling-PUBLIC/blob/master/src/lag... ) and therefore the settings in the repo should be fine for 2.4.x.

In case you want to compile the CFDEMcoupling toolbox with other OF versions you have the following switches:

Hello Community,

first of all a happy new year!

I have installed and configured CFDEMproject with OpenFOAM 2.3.0 and LIGGGHTS on Ubuntu 14.04 LTS (PC and VM), and has followed the steps on githubAccess_public.pdf.

Hi everyone, I need to know if CFDEM allows simulate wear on superfaces of geometry in contact with flows (fluids like water or slurry)

Regards

Hello to everybody.
Sorry for many questions but i'm working alone and don't have anyone else to help me. I follow the instruction in the http://www.cfdem.com/system/files/githubaccess_public.pdf

I have OpenFoam installed on my computer and installation of LIGGGHTS was passed smoothly.
But when i'm trying to install CFDEM "cfdemCompCFDEM" (after passing a few time) an error message appears:

Hello. I'm a new user of CFDEM. I follow the instructions in the githubaccess_public.pdf files.
After setting the environment variables in my .bashrc file I checked it by cfdemSysTest

The problems were:
valid:NO critical:yes - $CFDEM_LPP_DIR = /home/asorkin/LIGGGHTS/mylpp/src does not exist
and
valid:NO critical:no - $C3PO_SRC_DIR = /home/asorkin/CFDEM/CFDEMcoupling-PUBLIC-/src/c3po does not exist
