Ambient Temperature as Function in Thermal Transient (Mechanical)?

DeivideWinter · April 22, 2018, 18:44

Hi, everyone.
I am using Ansys Workbench 18.2, more specifically the Transient Thermal. I have a convection in which the Ambient Temperature needs to be a function that will depend on a variable that I'll call "Temperatute_Furnace".

But how and where do I define this variable? How can I do to this variable to change according to a equation during the simulation? Should I use Commands (APDL)? (if positive, how do I do it?)

I know I am quite lost, but I googled a lot and I didn't find neither the answer or a similar example.

Thanks.

Transient Thermal in workbench uses ANSYS as the solver. This is the CFX forum.

But in ANSYS you can define variables as equations. I did it a while ago but I cannot recall the details. I worked it out from the documentation, so have a look at the ANSYS documentation and you should be able to work it out.

Thank you for your reply.
I'll repost it on ANSYS forum, but I didn't find how to erase this post.
