Hello, I am trying to replicate the paper with simplified human geometry. I have created a domain, which is divided in 3 and meshed separately.

My questions are:

1. How do I do mesh verification (grid independence)? Do I just increase mesh nodes size by 50% for each region?
2. How do I create some kind of bond between different types of meshes so the data transfered is not distorted?
3. Can I cut the domain in half and apply symmetry boundary condition?
4. I tried to run the simulation with CFX with residual target 10^-5, Everything goes fine till 10^-4, but after starts to fluctuate. The solver gives a warning: "there is a some percentage of wall placed at the outlet. Please consider changing to opening type boundary condition." Any suggestions?
