Hi,
I am modelling a 3 zone problem (2 Solid zones and one fluid).
It is consisted of a steel die that is in contact with an aluminium tube which contains a fluid. The die is heated up and as a result the temperature of the tube and fluid goes up.
I am using Ansys 12.1 and I have imported the model from solidworks to ansys workbench fluent.
In the meshing cell the contacts between solids and fluid are defined(automatically) but in the setup cell(fluent), when I try to set the BCs for the contact surfaces to coupled, there is no coupled choice.
I have checked the contacts(at Meshing) several times and everything seems to be ok.
What is the problem?
Thanks
