Stones

Submitted by aharon.sanchez on Tue, 03/20/2012 - 10:58

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?

Restarting CFD-DEM simulations

Submitted by Somnath on Wed, 03/14/2012 - 20:58

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?

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

Confused in installation of CFDEM

Submitted by apurvkumar on Wed, 02/29/2012 - 06:30

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
