SubscriberI am trying to use midsurface instead of solid body in thermal analysis and even though I have assigned thermal properties but the temperature is not at all reducing whereas when I am using solid bodies, the temperature gets reduced as required.
Is there any setting to be turned ON or OFF for using midsurface in thermal analysis?

Ansys EmployeeHi
Can you post some inline images in your next post of the shell and solid bodies so forum members can see the difference in the results (also how you apply boundary conditions, etc.)
All the best

SubscriberCase 1: Using midsurfaces
Boundary condition
Mesh : Automatic settings
Result: It can be seen that there is hardly any difference in temperature even though all three materials are different
Case 2: Using solid bodies
Boundary conditions
Mesh: Automatic settings
Result: Here it can be seen that there is significant difference in temperature as per material properties.
Shouldn't midsurface case and solid case give same results? Please guide.
Thanks

Ansys EmployeeHi
There is a beta feature for that and will appear under the details of the surface body and below the thickness input (we can not provide much help if it does not work 100 % - e.g., the plotting in 2024 R2 is not 100 % straightforward).
Some info is below:

SubscriberThanks for the reply Erik. So, basically we can't use shell elements in thermal analysis without using this beta option ?
