Hi i currently doing a project to investigate the air flow for emboss shape coolling fin in soalr pv. However, i dont have any clue on how to simulation it using simscale as when i try to simulate it come with message "A setup with at least 28 regions is being used in a single-region analysis type. …

In the very first screenshot that you have shared, yes that’s one of the correct options for the seed face. What I did as follows: For the seed face, I chose this one: [image] For the boundary, all these faces on both sides (56 of them) of the geometry should be selected so that these faces will…

now i get it thank you very much sir for your help

however, sir my project is to study the flow behaviour around the fin…isnt that incompressible simulation is suitable?

In case you are only interested in the flow behaviour, Incompressible simulation type is the correct approach. However, temperature dependent effects are not taken into account in Incompressible simulations such as free convection in air. (No heat transfer) In case you are only interested in the …

ooh i see so if like that , it is better for me to go for conjugate heat transfer right…since i want to analyse the effect of embossed shape fin (solid) on the temperature of solar panel

I would say conjugate heat transfer is the most commonly used simulation type in electronics cooling application. You may want to follow this particular tutorial on electronics cooling by using conjugate heat transfer simulation. Step-by-step descriptions can be easily adapted to your own applicati…

alright Sir, thank you so much for your help without your guidance, i could not settle this problem related to my project. Good bless you Sir

You’re most welcome! We are happy to help. :slight_smile:

[image] Hi Sir, want to ask currently i am doing a incompressible flow simulation on the solar pv system. I am question which is after defined the inlet and outlet boundary conditon, do i need to defined the walls also for the boundary condition cause i see in the tutorial they defined the wall in…

if i use convective heat transfer, i could not get the temperature of the solar panel right
