CFDEM®coupling - User Forum

I am still trying to get CFDEM and LIGGGHTS running, currently the installation tells me to manually install VTK because Autoinstall failed, so I am doing it this way:

Recently, I encountered a problem when simulating a fluidized bed with temperature convection. The expermental setups are strictly set according to the paper (See Exp.pdf), where powder diameter is 1mm, with 57296 sand particles in a 0.08m*0.015m*0.25m chamber, the CFD mesh is mad according to the published paper as well, which is 32*6*100. I chose model type A and Gidaspow drag force model and the solver cfdemSolverPisoScalar. However, the powder bed cannot be fluidized even the inlet gas velocity (1.2m/s) has already exceeded the fludized velocity.

Hi , did everyone know how to get the interaction force (particle-particle,particle-wall) in CFDEM coupling?

Greetings Community,

I would like to install these two toolboxes using the following guide:

I am running a RHEL 7.6 (Maipo) w/o root and currently stuck at the step where I have to add

Hi everyone,
While running the Periodic Channel tutorial I encountered the following error message:

Hi, everyone.
I try to execute a coupled simulation with the cfdemSolverIB after I use decomposePar to divide it into four processors. Unfortunately, I receive following error:

--> FOAM FATAL IO ERROR:
[3] keyword voidFractionModelProps is undefined in dictionary "xxx/CFD/processor0 (1,2,3)/constant/couplingProperties"
[3] file: xxx/CFD/processor0/constant/couplingProperties from line 0 to line 0.

Hey everyone, I am currently using High performance computing cluster to run cfdem program, if I want to restart the process for many times, what process should I follow here. How am I gonna use restart files generated once the program was interrupted. I know how to restart the program for once, but not sure about restarting it for many times.

Thanks!

Hello All,

I am running CFDEM simulations of internally heated particles, with an external code determining each particles heatSource value. Currently I am able to run a single iteration, steady-state, case where by

Hi CFDEM,

Hello Users,

I am a new user for CFDEM coupling and I am conducting my thesis modelling high efficiency stairmand cyclone. I am using pisoFoam solver at the part of CFD and snappyHexmesh tool for building cfd mesh this part it goes well without any issue. when I came to the part of parallelization I faced the following error which is attached below..
I am stuck at this point I would really appreciate any help to be able to proceed with my thesis.

Regards.
