Cannot get the correct RBC distribution in pipeflow

[mojtabaAmiraslanpour]

Hello,

I am simulating the pipeflow case with the following configuration:

D = 32
Re = 0.5
plt_ratio = 0.1
H = 0.35

I see PLT margination happening in my case and it makes me happy but I cannot see the correct distribution of RBCs radial-wise. I expect to see the maximum number of red blood cells to be placed in the center of the pipe, but it doesn't happen. I get something like this when I draw the histogram for RBC locations after 1s of simulation time:

The horizontal direction is R which is the distance of the RBC from the center of the pipe.

No idea why it doesn't happen. Any help would be appreciated, guys!

Thanks

Maybe you don't normalize with the volume? It grows as r^2.

That was correct. I got the correct histogram after normalizing with the volume, Thanks!
