What is the boundary condition of the scalar for pipe flow in the code?

Hi, I wanted to know what type of boundary condition is used in the code for pipe flow if I turn on scalar. is it constant wall temperature or constant wall heat flux?
Looking for your answer.
Thanking you.

Hello,

By default it is probably imposed temperature set to zero but you will have to check the code to verify.

Thanks for the reply. That means constant wall temperature boundary condition?
