Hi All,
I have tried to adapt a case that I had running using the solver cfdemSolverPiso to add heating to the particles and run it with cfdemSolverPisoScalar. I made sure that everything looks correct from looking at the packedBedTemp example case. When I run the simulation I get the following error message:
Selecting locateModel engine

[0] --> FOAM FATAL IO ERROR:
[0] keyword engineProps is undefined in dictionary "/home/robert/CFDEM/robert-PUBLIC-4.x/run/PREXpolyhedraLaminarH2OScalar/CFD/processor0/constant/couplingProperties"
[0]

Dear All,

What force model does the cfdemSolverPISO use when it applied into the multi-size particle cfdem coupling system? Is it accurate enough? Any validation test has been done before?

Thanks

Dear all,

I run the cfdemsolverpiso tutorial case for fluid flow through a particle bed, however, I found that the generated image picture showed a big difference between the analytical ergun pressure drop and the simulation results. especially before the bed was fluidization. While the velocity was smaller than the minimal velocity, the simulated pressure drop was much larger than the analytical one? Can anyone help me explain this?

Thanks

Hello everyone:

when I want to compile PVReader with Paraview, I meet a problem. I don't know why? Can anybody help me?

Hi:

i just meet a problem when i want to install Paraview 5.4.0 through ThirdParty-5.x ,
my step: cd OpenFOAM
cd ThirdParty-5.x
./makeParaView

and there comes the download failed. do somebody knows what's the problem?

Downloading ParaView-5.4.0
./makeParaView: 112: ./makeParaView: curl: not found
Download unsuccessful
ParaView download failed. Re-run to retry download

Hi all,

I am simulating a case using CFD-DEM coupling package. I have successfully used "liggghtsCommands" in my CFD\constant folder and I can delete atoms in a certain region every coupling step. However, I don't expect the atoms are deleted every coupling step and I want to delete the atom every 1000 coupling step, how can I control the frequency of the liggghtscommand?

hi! Everyone!
I am a beginner I want to add a Saffman force for particle in CFDEM@coupling, Who can help me ?Thanks !

Dear Users,

Dear CFDEM developers:

I am now trying to run the latest CFDEM on an HPC cluster however after being able to compile LIGGGHTS, OpenFOAM and CFDEM the ErgunTestMPI fails with the below error:

...

[smic037:mpi_rank_0][error_sighandler] Caught error: Floating point exception (signal 8)

I am on a RHEL 6.9 cluster with

icc version 18.0.0
LIGGGHTS version 3.8.0
Latest OF5.x
