Hello,

Could anyone tell me on what Gap distance below Wurster tube depends ?And what is the expression to calculate "Normal coefficient of restitution"?

Thank you!

Hello,

I am Aharón Sánchez, and I have a doubt. I want to modelize the behaviour of a group of stones (near 63 mm of diameter) when some vibrations are induced in them. Can anyone tell me if this is possible?
How can I model vibrations?

Hello,

Can I restart CFD-DEM simulations from the latest Time (by simply changing controlDict)?

My restarted simulations run into an error immediately even though the simulations run correctly if started from time 0. I am also saving the liggghts restart files and reading from the correct restart file when I am trying to restart. Has anyone faced similar problems or knows how to restart a simulation?

hello all,

Dear cfdem experts,

I am trying to compile the latest cfdem on OpenSUSE 12.1 (64 bit) and ran into an error:
----------------------------------------
In file included from subModels/dataExchangeModel/twoWayMPI/twoWayMPI.C:30:0:
subModels/dataExchangeModel/twoWayMPI/twoWayMPI.H:47:62: fatal error: lammps.h: No such file or directory
compilation terminated.
make: *** [Make/linux64Gcc46DPOpt/twoWayMPI.o] Error 1

Hello all,

Dear every one,

I will be appreciate if anyone tell me why the following error is produced after first simulation on liggghts.

Thanks in advance

Cheers,
Ebrahim

Hi Everyone,

I am new to OpenFoam and CFDEM. I have been trying to install CFDEM and I am stuck in activating the new bashrc file. After I execute this:

#- set the cfdem environment variables correctly
gedit $WM_PROJECT_INST_DIR/$USER-$WM_PROJECT_VERSION/src/lagrangian/cfdemParticle/etc/bashrc &

Should I paste the contents in the bashrc file in home directory or just activate the bashrc using command . ~/.bashrc?

I tried both, and I find this in my bashrc file:

#- source OpenFOAM-1.7.x
. $HOME/OpenFOAM/OpenFOAM-1.7.x/etc/bashrc
#- enable parallel compiling

HI,

I am wondering whethere there is any info on CFD-LB shown on this web site.

Thanks!

Hi, I'm trying to compile CFDEM under Tuquito 5 x64

i've installed succesfully OpenFOAM 2.1 and ThirdParty 2.1, and ligggths
but when i'm compiling CFDEM 2.0 beta according to system/files/setup_LIGGGHTS__OpenFoamR_CFDEM_2p0_on_Ubuntu1004_24052011.txt

these error occur
