Default jump in BC

Hello,

Is it possible to prescribe a jump (using UDFs)in boundary conditions. For example, I want to prescribe a jump in the energy equation's b.c.

Thanks!

I doubt if you can prescribe an energy jump. The jumps might be possible in primitive variables.

Thank you very much for your answer. What do you mean by primitive variables?

Well yes, I want a temperature jump. Do you know if this is possible?

Thanks

Yes You can define an UDF which gives the temperature jump as BC.
