CFDEM®coupling - User Forum

Hello every body,

I want to start working with liggghts and I do not know how to install it with openFOAM 2.2. Would you please guide me to the installation page?

Thank you

Hi CFD-DEM developers,

as the fluid force acting on immersed body is:
f = - grad(P) + nu_ * laplacian(U)

I found that the last line in the following codes seems having a written error:
volVectorField h = rho_*(nufField*fvc::laplacian(U_)-fvc::grad(p_));

as mu = nu * rho

Hi,

Is it there a way to install and run LIGGGHTS and CFDEMCoupling with OpenFoam 2.2.2 ?

Best,

Hello CFDEM users,

Hi All,

I met a post-processing problems after CFDEM running. After the coupling running, two figures will bump up and I could check the results in paraview, however, sometimes if I close the figures and paraview, the dump*.** files in the DEM/post will disappear. It happens sometimes but not always! I am not sure where is the problem. Does anyone else have the same problem, and how to fix it? Thanks so much for the help and suggestions!

Thanks!

Hi,
How is it possible to do modeling with two dissimilar particles types using cfdem?
Thanks in advance,

Hello Dr. Goniva/ cfdem users,

I compiled successfully the cfdem src with the comp switch 'on' and then compiled cfdemSolverPisoScalar solver which also compiled successfully. When I ran the 'packedBedTemp' tutorial, It gives error. Is this case tested tested or have I ignored something. The log file is attached herewith.

Hi

I am looking for an solver like interFoam + DEM. Could you have any helpful information.
I am not sure if it is difficult to implement this solver. Can it be implemented by referring to
solver cfdemSolverPiso to do same ways with existed classes. Does it need to create new
classes for multiphase solver.

Thanks in advance.

Where can i find a source code of this simulation?:

http://cfdem.dcs-computing.com/media/DEM/nonspherical/multisphere_packin...

If this example is not provide on the website. Can you give me a guide "How to make non-spherical simulation"?
