Hi @ialhassan ,
The linked project seems to be private, so I can’t know for sure what is wrong. Based on your description, you probably defined a boundary condition to an interface, which is not allowed.
Please refer to figure 6 from this documentation page for more insights.
PS: a couple of ways around it:
- Since the battery walls are at a fixed value anyway, you could potentially remove the batteries from the CAD model after generating a flow region, and set the fixed value boundary conditions directly to the flow region. Without the batteries, you won’t have an interface anymore.
- You could also carve a “void” inside the batteries, assigning a fixed temperature condition to the inner face. The objective here is to avoid having an interface to allow you to set a boundary condition
Cheers
