Hi,

I'm trying to reduce my mesh size by cutting my model in half. Unfortunately, for my model there is a gap between the roof and the underside of the solar panel (this is a single solid). I subtracted the solid from the fluid domain and then halved my fluid domain along an axis of symmetry. However I'm now left with two surfaces which i have to specify as symmetric to fluent. Is this alright?

I did say not to give the panel a thickness. n

Hi Rob, nThanks for replying. I did try that way but I'm concerned about the mesh. When I mesh two solids (fluids) one inside the other, the mesh is different for both. How do I tell fluent that they are the same thing with just a panel on top? nSecondly, there is a panel holder which needs to hold the panel. It just seemed complex to me to do this because I'm new to all this. nWhich is why I'm at this point just making the model like this. If you could give me some specific method of doing this I will be very grateful. nIf not, could you let me know if what I did right now is right as well?

That's where share topology and multibody parts come in. That connects the geometry so mesh is conformal. nSupports etc can be modelled using porous media, it's covered in the Cell & Boundary condition section of the User's Guide. Equally, we can float things in mid air by magic because we're using a computer. n
