I am trying to do thermal analysis, and part of the material will have self heat generation while the other part of the material does not.

So I was trying to use activate component to draw this self heating part from the solid I have. However, I cannot use activate component since it is in grey shown in the image below.

Can anyone help me? I am also not sure if part of the same material gonna behave differently from the other part, do I need to use activate component to edit this solid to have different parts, or I should have two different solids with one having a hole and let small solid inside of the big solid. Or just simply draw two solids with them overlapping with each other?

Hello, 

You will have to first move the solid to new component and then you will get an option to ''Activate the component'' for modeling. 

To specify self heat generation to half of your model, you can split the body into two halfs and try defining thermal conditions for the half part.  Also you can then define different material properties for both as it will split them into two seperate solids. You will have to use ''Split body'' command from the Design Tab for this. 

Let me know if you need further assistance. 

Thank you,

Devendra

Thank you so much for the response. I actually ended up with drawing two solids and put them together.

I am planning to use Ansys Mechanical to do the thermal analysis with partially heat generation.

The only data I am provided is the size of the part (I have drew it as a separate solid) does the self heat generation and the total power of heat it generates. I am not sure whether Ansys Mechanical has the option for me to set up the power or there is a better way to do it.

I see some tutorials online also use Ansys Discovery to run thermal simulation. Do you have suggestions which one is better between Mechanical and Discovery? (In my case, I have several different materials contacting each other tightly shown below. No gaps in between.)

The part labeled in red is the heat generating part.

You can do Thermal analysis for this model in both Ansys Disocvery and Ansys Mechancial. Both have the required capabilities to do thermal simulation like this. 

Please refer Solid Thermal Simulation in Ansys Discovery | Ansys Courses and Heat Transfer in Structures - ANSYS Innovation Courses for more information.

Thank you,
