CFDEM®coupling - User Forum

I installed LIGGGHTS yesterday,after run cfdemTestTUT,it opens two terminals .One of them named 'cfdemSolverPiso settling Test CFD',
I thought it might open a paraview,but actually it doesn't.It open a Document Viewer window,and shows
"Unable to open document
Error opening file:No such file or directory"
I don't know why.Pray your answer.

Hello everybody,

I am trying to install CFD-DEM on my Ubuntu 12.04 machine (via VirtualBox).

So far, I seemingly installed with success OpenFoam 2.1.1 and git-cloned LIGGGHTS 2.1.2 as well as CFDEMcoupling 2.1.1.

My problem is that the compilation of LIGGGHTS through command
"cfdemCompLIG" failed with the error message "virtual memory exhausted: Cannot allocate memory". The original OS of my computer is Windows; I installed VirtualBox and Ubuntu 12.04 on it, without trouble.

Hello,
Can someone please help me out with this error mentioned below. I have run the same script on LIGGGHTS successfully but it's showing error in the CFDEM solverpiso. Even pair style i changed to gran/hooke/history, it wasn't working with gran/hertz/history. Thanks in advance.

Hallo Christoph,

I intend to couple multiphase flow using VOF method (e.g. atmosphere and water) with Liggghts. It seems that CFDEM only supports single phase flow right now. So i would give a try to make a rasInterFoam solver with CFDEMcoupling. Is there some useful papers or tips to do this?

Thanks.

Cheers, David.

Hello:

When I use the git command:

git clone git://github.com/CFDEMproject/CFDEMcoupling-PUBLIC.git CFDEMcoupling-PUBLIC-$WM_PROJECT_VERSION

After downloading I obtain the following directory:
CFDEM-coupling-2.1.1

This means that the version I downloaded is 2.1.1? In this case how could I dowload the latest version since the git manual does not ask me the version that I wish to download (version 2.4.4)?

Cheers

Rafael
