Internal pipe temperature setting

yuruka · April 7, 2020, 02:44

Hello

I am simulating a double tube structure.
I want to set the outer tube to 600K and the inner tube to 900K, but the inner tube can only set the temperature at the end.
What is wrong?

What do you mean by setting the temperature? Do you mean initial temperature, i.e., temperature at time 0 s and then you want to observe how it evolves in time? Or do you mean temperature at boundaries? If it is none of these, then most likely you want to fix the values. This option is available under Cell Zone Conditions. Do note if the cell zones are solid and you fix the temperature, then there is no point in having the cell zone itself. You can just delete the cell zone and apply that temperature as boundary condition.
