Rigid Body Motion

Lattice Boltzmann Method LBM: Theory
#1

Dear All,

I’m interested in coupled simulation of rigid body motion and fluid flow. I read some of the immersed boundary condition papers available, and I think that is a way to proceed. But I’m wondering, if there isn’t a way to model the rigid body motion in a pure LBM fashion, thus avoid the coupling with other solvers!? Please, is anyone around who likes to discuss this?

Regards, Francois

Hi,

I used the Immersed boundary method to include rigid fibers into the LBM. There surely exist many different techniques how to include rigid bodies into the LBM. The most simple is to include bounce back scheme and prescribe velocity to it. What exactly would you like to discuss? :slight_smile:
