How to give boundary conditions for one parametric roof form in a building?

I have one roof form as a solid mesh. I want to do wind analysis for the same. But i hace problems to setup the boundary conditions. The velocity inlet and outlet has to be in two separate parts of the same form. But it it detecting the whole model as one plane only. As it is a parametric form, Im facing issues

Hey abhirambiju000,

Thanks for posting on the Forum.

To run a fluid flow simulation like wind analysis, you need the flow volume instead of the structure boundaries as your model.

Did you create the flow volume on the model first? Here is how you can do that: How to Create Flow Volume Extraction? | Knowledge Base | SimScale

You will then likely have the inlet and outlet face on the volume that you can select separately.

Best,
