Hi @hiq , Thanks for posting your question! Taking into account that everything is a fluid domain, at this point down below the fluid face is getting a sharp end which makes difficult the mesh conforming. [Screen Shot 2023-06-20 at 10.13.50] Otherwise, as it is just a small region behind the imp…

Hi, Thanks for your help. [relaxation factors] I just want to confirm this is the parameters that you change right? If you don’t mind can you explain why decreasing the relaxation factors help. Many Thanks,

Hi @hiq , The most easy explanation on relaxation factors can be found in this page: [image] CFD Numerics Page: Relaxation Factors | SimScale This document explains how to use the relaxation factors in order to ensure the necessary stability and convergence of the CFD simulation. …

hey, thank you so much for explaining, it helped me. ▶
