Hi, I´m new in SimScale and I’ve done a little experiment which I like to share and discuss.
I’ve done a convergate heat transfer simulation with a very easy geometry like you can see in the picture.
Because of this easy geometry I can calculate the outlet Temperatur without any Simulations. So I know that with an inlet flow of 0.4 m/s (d=0.55mm) the outlet Temperature is around 364K.
Now I wanted to check this result with the simulation result. I get for different meshes different results like you can see in this table.
My questions are:
- are hex dominant meshes better for this simulation?
- how do I know which result is the “right” one if I can’t check it with analytic calculations?
- is the first layer thickness important for the meshing, especially if it is a laminar flow?
I hope this was understandable.
Here is the project:
