No analytical model for curved wall

[aamostafa87743906]

Hi

I am trying to create a structural floor from a curved mass, and it seems the only way that's possible if I model it as a structural wall (!) and choose the face of mass to create a curved concrete wall acting as a roof (image below)

However i am facing a problem that this curved wall (roof) doesn't create an analytical equivalent in the model. Even selecting this wall doesn't give an option for enabling analytical model which is a bummer as I am trying to export the analytical model from Revit for analysis.

Is there any way to create an analytical model in Revit for this curved roof ?
