Error in Installing CFDEM coupling.

Submitted by atul2018 on Tue, 01/19/2021 - 14:23

Hello All

I have tried to install the CFDEM coupling along with the software packages OpenFoam and LIGGGHTS in my Ubuntu system (Ubuntu 20.04.1 LTS on virtual machine). I am following the instruction from the CFDEM website (https://www.cfdem.com/media/CFDEM/docu/CFDEMcoupling_Manual.html#install-3). But when OpenFoam is downloaded from git (recommended version OpenFOAM-5.x) and compiled by adding the following lines in .bashrc and running the ./Allwmake.

export WM_NCOMPPROCS=4
source $HOME/OpenFOAM/OpenFOAM-5.x/etc/bashrc

The compiler reports: ake: *** [/home/workstation/OpenFOAM/OpenFOAM-5.x/wmake/rules/General/transform:25: /home/workstation/OpenFOAM/OpenFOAM-5.x/platforms/linux64GccDPInt32Opt/src/OSspecific/POSIX/fileMonitor.o] Error 1
make: *** Waiting for unfinished jobs....

I don't understand why i get this error in spite of following the exact instruction mentioned in CFDEM website.

I also tried to compile openFOAM directly from openFOAM website ( https://openfoam.org) both the newest version (OpenFOAM-8) and recommended version (OpenFOAM-5) and then couple it with LIGGGHTS using CFDEM coupling. OpenFOAM-8 installed and compiled but is not supported by CFDEM coupling. OpenFOAM-5 doesn't get installed showing error that some files are missing.

It would be great if someone can help me to fix this issue.

Best Regards
Atul
