Mesh strategy for 5 bodies geometry to be used in FLUENT
I am trying to do the mesh of a water solar collector, which is composed of 5 materials: Fluid, Solid (representing the thickness of the tubes and collectors), absorber, glass and a cavity (representing air). As I am interested in modelling heat transfer and fluid flow among all bodies in Fluent, after being reading the guides I understood that I need a conformal mesh. Therefore, in Desing Modeller I create the 5 bodies and I generate a New part putting inside it the 5 bodies, see attached file.
I was doing the mesh tutorials and workshops, but I am a bit lost and I do not what type of strategy to follow for doing a mesh with the smallest number of nodes, I am completely lost and I do not know which strategy to follow. The tutorials available are focus on single bodies. Any recommendation on the strategy to follow for this case?
The geometry is shown on attached file
Thank you in advance,
