Hello all,

I have an interesting issue and I don´t know how to solve it.
For my pipe flow model with CHT I did a few first tests on the mesh where only the fluid domain is activated, it works out pretty good.
But when I run the entire model with the solid bodies around it, I do not reach my convergence criterion for the continuity equation.

I don´t understand what is wrong there, has anybody a clue about this?
Actually nothing changes in the fluid domain except temperature, but I am even not working with temperature-dependent properties.

Thanks for your help!
