I use Fluent Materials Processing to simulate polymerflow through a nozzle.

The thermal settings of the wall boundary condition iritates me.


I would like to map convection of the hot nozzle onto the melt.
the options are as follows:
- 'Temperature'
- 'Convection'
- 'Heat flux'
- 'Heat flux and convection'
- 'Temperature profile'


Do I need to select 'Convection' or what would be the difference with 'Temperature'? Would there be no convection if I select 'Temperature'?

If i select 'Convection', i also have to specify the heat transfer coefficient.


Thank you very much!

Can no one help me?
I guess it's a "stupid" question and many here in the forum know directly what to choose
