2-D pipe mesh
 

hi all

This is my frist time to use ansys

I have a heat pipe (aimeter is too smal , l,ke 2 mm), and I am going to study on volume fractions.


I have attached my heat pipe, it sonsits of 3 parts,
top is : condenser
bottom is : evaporator
middle part : adiabatic

So, could any one can help me, how should I make mesh, I mean my mesh what should be like?

type be, rectgilar or triang. ?
Face mesh size?


and can some one explain me, what is refinement?

Thanks ...
