I 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?

Hi

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

Done

Case 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

Hi

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:

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