LBM code: OpenLB or Palabos?

Hi, I'm trying to do a simulation of fluid flow and heat transfer in porous medium for geothermal applications. I wanted to know between OpenLB and Palabos which one would be a better choice?

Also if wanted to simulate the mechanical processes (porous medium displacement due to high pressure of fluid flow), would it be possible to do that with these softwares?

Any help and suggestions would be appreciated

There are currently several options for open LBM (lattice-Boltzmann) codes. Quick search gives at least the following: OpenLB, Walberla, Palabos and Musubi.

Our application will be flow in tomographic images of fibrous porous materials (porosity 50-90%) with low Reynolds number. The networks are homogeneous enough so that load balancing is not obligatory. Also, no need for grid refinement. Solid-fluid boundaries will be accurate enough with simple bounce back combined with the MRT collision operator - more sophisticated boundaries are not needed. The simulations are performed with a single powerful windows workstation.

My simple question is: What open LBM code to choose for these simulations? We have currently looked mainly at openLB, but would in our case another choice be preferable?

I am entirely new to LBM and statistical methods. Can anyone please suggest good starting point for the same? Any good books or video lecture links will do. I am proficient enough in programming and currently I am working on FDM and FVM.

hey guys

we are currently working on applying LES model on Lattice Boltzmann Method for simulating flow around cylinder and similar geometry.if there is any open source code which done this job its your kindness to address it to me

any relative comment is welcome

I am looking for an open-source finite element analysis library for Python programming language.

I want to develop my own finite element software in the specific study and also for my academic studies. Please share your opinions about the various free FEM library for python with your experience.

Hi all,

I am a PhD candidate trying to model a fluidized bed reactor with liquid-solid fluidized bed reactor. There is no gas. The solid fraction is not fixed at the moment so for maximum flexibility of solid fraction and for ease of using the code (easy to understand and modify). Which opensource LBM software would you all suggest? Thanks in advance!!

In a flow over rotating cylinder simulation, if the cylinder keeps changing its shape with respect to different angular position during rotation. How to specify the shape changes of the cylinder in the transient analysis case?

I didn't realize that RG would actively send requests for feedback. This is not something I wanted to trigger. I expected that this action would allow other researchers to provide feedback, which would be the reasonable thing to do imho.

So I'd like to undo that action.

Hi again,

I am trying to understand how the setting of inlet in the FLUENT, specifically, the Velocity Magnitude and Direction. Someone could explain me, please?

I'm working in 3D domain.
