CFDEM®coupling - User Forum

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

Hi Everybody,

I am trying to set up CFDEMproject on ubuntu 14.04 LTS, and I am following the same exact steps on githubAccess_public.pdf.
The compilation run for a while and in the end gave me the following :
“.

a - write_dump.o
a - write_restart.o
make[1]: Leaving directory `/home/almsahli6/LIGGGHTS/LIGGGHTS-PUBLIC/src/Obj_fedora_fpic'

Hello CFDEM forum,

I'm new in with CFDEM, and i'm facing the same problems as discussed in CFDEM Compiling Problems. I have this error:

Unable to open document
file:///home/dina/CFDEM/CFDEMcoupling-PUBLIC-2.3.1/tutorials/cfdemSolverPiso/ErgunTestMPI_cgs/CFD/octave/cfdemSolverPiso_ErgunTestMPI.eps

Someone posted to change the path values, so I looked at the file "totalPressureDrop.m" in /tutorials/cfdemSolverPiso/ErgunTestMPI_cgs/CFD/octave/ and I have this path values

%path = '../probes/0/p'; % 2.1.x
path = '../postProcessing/probes/0/p'; % 2.2.x

The file CFDEMcoupling-PUBLIC/src/lagrangian/cfdemParticle/cfdTools/versionInfo.H mentions a particular version of OpenFOAM compatible to the CFDEMCoupling-PUBLIC. The version mentioned is "OFversion="2.3.x-commit-4d6f4a3115ff76ec4154c580eb041bc95ba4ec09":"
Can anyone tell me where to find in git this particular version and how to install it.

Hi,

I am trying to write a new solver to couple the compressibleMultiphaseInterFoam and LIGGGHTS, using the cfdemSolverPiso solver.
I want to know forces on the particle and not to have the effect of particles on the flow. So the flow should be solved independent of the presence of particles.
I created a solver and it is compiled successfully. The problem is when I run the solver I get the following error.

Hello everyone

Since few days I am trying to install and run CFDEM coupling. After several troubleshooting and help of Christian Richter. I managed to install CFDEM, OF and LIGGGHTS properly and run the tutorials partially. When I run tutorial cfdemSolverPisoScalar/packedBedTemp then I get peculiar errors related to LIGGGHTS. The log file for this run is attached. The part of terminal output is pasted below.
[Anyone please help me hint to get rid of the issue]

Similar error I am getting for the cases cfdemSolverIB/twoSpheresGlowinskiMPI, cfdemSolverPiso/ErgunTestMPI

Dear all
I have some questions when run my cases.Firstly,the "nr particles" sometimes decrease or sometimes turn to 0 immediately at some timestep,and this often cause divergence of my case.And I try to increase youndsModulus peratomtype,but I found this method might change the nr particles in the first timestep.How can I solve the problem? If anyone can give me some advices ,I would very very appreciate. Thanks

Good morning to everyone,
I am trying to create a dynamic mesh around some particles sedimenting inside a container of constant volume. My problem is that I cannot find out what kind of scalar I can insert for "field" in the DynamicMeshDict file.
Please help me, I am in a great rush!
