Hi all,

I've been simulating fluid flow within a pipe with baffles to enhance heat transfer, my mesh has worked fine with larger spacings even with LARGE baffles that take up nearly the whole pipe. However, now with a small spacing ratio my residuals are diverging, i'm assuming this is because of the massive turbulence the baffles have induced. I'm not sure how to refine the area circled in red but I think that's where my problem lies?


If anyone could help it would be greatly appreciated, or if anyone has any other suggestions as to why this is happening?

Thanks!
