how controll mesh quality
 
hi all
i have generate a mesh with cooper scheme, but the quality is not very good. after some trial i can do a mesh that don't have negative element and no equisize>0.97. the problem that the worst element is about 0.8.
what are the parameters that i must controll?

Basically you need to control the equisize skew
Go and check the quality by clicking the icon at the bottom right.
Worst element with 0.8 is quite good.
I have no problem with mesh (unstrutured), which max equisize skew is 0.9

ok.
if i want to better mesh what can i do?
thank you for all max!

try to understand why are the cells so skewed, and try to correct them with size function, etc...
But as I said 0.8 is good.

reference of meshing
 
Hi All!!!
Is there a reference to say that our meshing is good??:confused:
Can you tell me that reference??:confused:
Thanks

check gambit help... but it s just theory.
Your self-experience will be helpfull..
From my side, I try to get mesh with max equisize skew about 0.9 (complex geometry with tetra-hexcore elements)
