Hi guys,

I have serious convergence problem in my case of two phase laminar flow and heat transfer in fluids. It is not a big deal. Just a box with inlet and oulet - for the flow - and one temperature boundary source and time dependent analysis.. . At the beginning there is nitrogen inside and another gas is going through the inlet and is mixing with the nitrogen. At the same time, there is a temperature at one boundary. I just want to know what is happenig with the density of the mixture in time.

Is there some trick how to couple these two analyses? It works fine separately, of course...

Thank you in advance!

Katerina

Hi,

Did you manage to solve the problem because I'm facing the same one? I really hope you did :)

Hi,

I am afraid I did not. I had to solve the flow in the vessel and the temperature distribution during the day. Of course, it would be great if I could couple these two. But the results had to be quite quickly presented so we satisfied with the separate analyses this time ... Then I didn't come back to it. Sorry ;( But if you have any suggestions or somebody here would be great!

Best regards,
Katerina
