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

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.

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)
