Hello everyone 

I am trying to simulate heat trasnfer between multiple domains shown as following. The domains from top are solid, liquid, solid, liquid, and liquid.

The model used was k-e realizible 

The inlet for bottom fluid domain was pressure inlet of 5MPa
The inlet for fluid above bottom domain was pressure inlet of 6MPa

The inlet for fluid at the top domain was pressure inlet of 6MPa.

The fluid specified for the top two domains was kerosene and ideal gas air for the bottom one

OK, what's the problem?

Sorry I didn't mentioned the problem more clearly
The problem i am facing is I am getting divergence error and the tempreture distribbution is not correct. This is what i get

 and what i expect is something like this

 

Thses are the errorrs i am facing

OK, part of the problem is you have different fluids touching - ie there's a cell zone with air in it. Should that be kerosine? Otherwise find the interior that bounds the two zones (7 & 8) and make it into a wall. 

See how that behaves.
