How to Perform Equilibrium Checks on Transient Heat Transfer Numerical Models


When conducting heat transfer studies using the Finite Element method, users need to make sure that their model satisfies thermal equilibrium. This is straightforward for the static case. But for transient simulation, the amount of heat flowing into your control volume does not always equal the amount flowing out. In fact, this lack of equilibrium defines a truly transient condition.

In the following presentation, PADT’s Alex Grishin explains the math behind thermal equilibrium and how to perform a proper equilibrium check on transient models.

If you have any questions or want to learn how the experts at PADT can assist with our transient thermal simulation or any other type of simulation, please contact us.
