Hi,

I am quite new in CFD. I would like to do a project with OpenFoam about under floor heating system and i have a water pipe(plastic) it has certain and constant initial conditions(Temp, Pressure, mass flow) and i have different materials around the pipe with different thermal diffusivity. I want to see the relationship between return temperature and thermal diffusivity at the end in post processing graphically.

i am struggling to creat my blockmesh. Is there any tutorial which i can maybe manipulate a little bit the geometry and try to fit to my case? I would be appreciate for any help or advices.

I am adding also a picture of my plan. Could you please also check this out.

Thank you.
