I am new to palabos. I am learning LBM and trying some examples. I am trying to simulate 3-D Poiseuille flow in circular cross section with Velocity Parabolic Inlet and Pressure boundary at outlet. Please help me in this.
My aim was to see how long it took Palabos to convert a block profile at the inlet into the correct Poiseuille profile. In the end, I tested this in two different ways:
by setting up the lattice by defining fluid nodes
by setting off-lattice boundary conditions for the pipe walls
Let me know which of the two you’re interested in (the second one gives nicer results).
Thanks for the Response. I was kinda busy with my exam. Lemme start my work and post the code where i struck. If possible, please email me at mdgowhar@iitgn.ac.in .
