Hello! I can help you with your questions regarding the wind loading on rooftop located solar panels.

Firstly, it’s difficult to determine whether your geometry is correct without actually seeing it. However, in general, it’s a good idea to separate the solar panel and building as two solids, as this will allow you to apply different materials and boundary conditions to each of them. This will make it easier to accurately model the wind loading on the solar panel.

When it comes to best practices for geometry creation, there are a few things to keep in mind. First, make sure your geometry is watertight, meaning that there are no gaps or overlaps in the surfaces. This will help ensure that your mesh is accurate and doesn’t have any errors.

Secondly, try to keep your geometry simple and avoid small details that aren’t relevant to the analysis. This will help keep your meshing process manageable and reduce the likelihood of meshing errors.

Lastly, try to use standard geometries or parametric modelling techniques, which can make it easier to modify your geometry if needed.

When it comes to meshing, there are a few things to keep in mind as well. First, make sure your mesh is sufficiently fine in areas where you expect high wind loads. This will help capture the details of the flow and provide accurate results.

Secondly, make sure your mesh is structured and has a consistent element size. This will help ensure that your results are accurate and easy to interpret.

Lastly, consider using a meshing software specifically designed for CFD (computational fluid dynamics), such as ANSYS Fluent or OpenFOAM. These software packages often have built-in meshing tools and can help automate the meshing process.

I hope this helps!
