I'm running a transient thermal simulation on an assembly and have noticed that changing the materials used for crucial parts does not seem to affect the time taken to cool. Could this be related to the assembly not being fully defined? If not, are there any other suggestions as to why this is the case?
I've attached the model to this message. The parts that I am interested in changing materials for are the 4 aluminium rods surrounding the central rod. To find the time taken to cool to ambient, I am probing the central rod in the transient study 2.
I have not had a chance to take a look at your model
can you make sure that it is a pack and go? it looks like just the sldasm
also what part/assy should we look at?
what config?
and what study? can you make sure both your transient sims are in the model?
i'd also suggest you start with a really simple block to make sure that your understanding of the concepts is solid (maybe a problem with known results) and also that the software is working. then you can move onto your model.
and to note, not having the assy fully defined won't make a difference. mates, sketches...etc don't matter in simulation. but you need to make sure there is a heat path through bonded components. (touching)
We'd need to get a closer look at your model and how it's defined and what you're changing. Can you post the model?
