Hi I am trying to simulate a group of falling rigid spheres in a confined domain

[Aritra Roy]

Hello guys,

        I am a student of the Indian Institute of technology (IIT) Bombay, India 

I wish to simulate a set of falling rigid spheres inside a confined domain and replicate the paper : https://doi.org/10.1016/j.apt.2024.104369 (pdf also attached) using ibamr. 

I am completely new to the software though I am aware of what immersed boundary solver actually does and how it works by adding an extra body force in the momentum equation. 

I am currently using WSL and quite familiar with linux OS can somebody help me in how shall i start to simulate this 

feel free to write to my email id and for discussions I am in dire need of help - 25M...@iitb.ac.in

Thanks in advance !!

Hello Aritra, 

The best way to install IBAMR is by using autoibamr (https://github.com/IBAMR/autoibamr). It should work on WSL as well, see this discussion

The problem you mentioned can be solved using ConstraintIB module of IBAMR along with a DEM solver. You can see this (https://github.com/nayaksagar/PRELIMPFlow)
