Can't calculate simple convection
I'm not an expert in Fluent, all I want is to calculate convection for vertical cylinder in air
Created simple 2 body model: cylinder (solid) and body of air (fluid) around (another big cylinder). Meshed and assign inlet/outlet to bottom/top of air cylinder
In Fluent I got two cell zones (cylinder and air) and bunch of some "interiors". One wall "wall-air". Assigned to cylinder cell zone heat source (constant flux), to inlet/outlet - pressure inlet/outlet. Calculate.
Nothing, energy doesn't transfer from cylinder to air
Tried another approach with cylinder and enclosure - got even more "contact region" surfaces and many walls with same result
I have been reading manual for 4 days already and didn't get a slightest clue how to make it right. Can anybody point me into the right direction?
