Hi, The main differences between conjugate and convective heat transfers are: Conjugate heat transfer allows multiple flow regions Conjugate heat transfer requires you to add the solid parts as well (so here we want to have the solid walls). For conjugate heat transfer analyses, you will only be …

Hi there, are there any openings on the hut? Can you send me a screenshot please? Best regards, Fillia

No openings. That is why I am getting 2 separate models when Boolean differencing the model into a solid block. Here is my model [image] Here is my model Boolean differenced in a block to create the flow region [image]

I see, the two flow regions should be connected with an opening, otherwise you will not be able to run the project. The only analysis type that can simulate more than one flow region (that are not in contact) is the Conjugate Heat transfer . For this, the hut will remain in the model. Have a look at …

Hmm, I dont want airflow to get inside of the model though… The purpose of the simulation is test the internal temperature of the hut without ventilation. If I connect the outside flow region to the interior, wont simscale simulate air entering into the hut?

Exactly, so it might be better that you use the Conjugate Heat Transfer then, that allows having two separate flow regions :slight_smile:

Ok I will try this out. I am using this study to compare it to a similar study model that has windows in it. This study is linked here as reference. Forum: [image] Trying to create a Convective Heat Transfer Model Project Support I am trying to create a Convective Heat …

So is there any way I can just test the internal heat temperature from the occupants without having open windows?

Yes, by closing all the openings (and running a simulation only with the internal flow region). You’d have to specify some heat dissipation mechanism, probably from the outer walls of the domain. The setup would be similar to the office room simulation.

So I would only import the model I circled in rhino? [image] And what part of the office room tutorial goes over heat dissipation?

Correct, it would only take the internal flow region. The typical boundary condition would be similar to section 2.3.d from the tutorial (of course with different temperatures).

I am experiencing this error message when running a simulation. Would you happen to know why I am receiving this?
