Hello,

I've been working on a transient thermal analysis, but the temperature data from this cross-section seems weird.

This figure shows an overview of my mesh settings.

 I applied different mesh sizes in this model to reduce running time.

The blue region is my heating area.

Any suggestions would be greatly appreciated. Thx!

should I do diff mesh type or mesh size should not differ too much

cuz this case is about cost 5 days....

Hello,

It would be difficult to comment without looking into the model (Ansys employees cannot download the model). Some suggestions - what if you use linear and uniform mesh? Do you see an unexpected behavior?

Isee 

The model will look like this when viewed from the side, width = 10um

and i wanna know surface temp. between no.4 & no.5

The current results confuse me, here's some pic of my result

 

at specific time, the highest temperature is about 32 degrees at the surface between no.4 & 5

and this is the path temp. data in the same surface

 

Here is the problem, why there's big temperature difference at the lower interface when the heat is conducted from top to bottom.

 

thx anyway

need some help here

Hi,

Can you check the heat flux vector plot for how heat is flowing?
