I am simulating a computational model consists of steel hallow rectangular box with 0.5mm thickness and solid brick inserted into it.
the top wall of steel is given as convection BC and remaining walls are adiabatic. coming to inside brick top, i have doubt in specifying the BC.
I mean, should it be a coupled wall? if so then what might be the coupled wall material. please explain solid-solid boundary condition (3D)

Which solver are you using? In Fluent a wall between two zones can be zero thickness (coupled) so has no effect on heat transfer. Mechanical behaves differently.

thank you for Ansys team for clearing the doubts..
Here I want to know about parallelization of UDF.
I want to run a computational model in parallel mode where i have interpreted UDF for variable convective heat transfer coefficient. is it necessary to prallelize the UDF please help me

It depends: there's a section in the manual explaining what/when needs to be altered. Simply, if you need to loop over surface facets to calculate something you need to parallelise the code.
As an aside, please keep threads clean by asking one question per thread and marking posts as an answer if they are. No need to do anything this time (ie don't delete any posts) but please remember for next time.
