How to input time varying temperature condition in ansys steady state thermal
 
hello,

As, I am started using Ansys for my research i have a doubt is how to input the temperature which is varying over time like ambient temperature or can i input sinusoidal temperature pattern for analysis of my material. I am studying the behavior of material exposed to high atmospheric temperature to analyse its insulation. So, please anyone can clarify me how to do it.

Hi,

This doesn't seem too complicated to achieve.. for instance, use function/ expression (create a sinusoidal/ time-based temperature CEL) instead of constant value when assigning temperature in CFX. The syntax should not be that difficult to find both here in the forum or a quick google search.
Though I believe to study insulation behavior w.r.t dynamic change in ambient temperature as you intend to would be a next step (if at all) to separately evaluate the material at an array of different ambient temperatures for initial idea/ conservative bench marking.
Cheers.
