Calculation of 2D Aspect Ratio

Recommended Posts

Dear all,

I have one element (quad)

I check its aspect ratio by F10 panel is ~3.4 but when I check by quality index, it is ~4.2

What is wrong?

(settings: minsize => shortest edges, aspect => ideas)

Please help, if it is hm bug, was it fixed in HM2017?

 

the element:

aspect_calc.fem

Does anyone know how value 4.23 was calculated?

In hm help document, ideas aspect of quad is calculated by maxlength/{sqrt(2)*interior_circle_radius} ~3.4

 

Could you check if anything updated in HM2017?

Hi Tinh,

Yes, I noticed the difference. These values are different for F10 and quality index panel.

I'll check internally and will update you very soon.

Thanks, but with minimal normalized height, my element must have aspect equal 5.39/1.18 = 4.56

and I am calculating aspect by ideas formulation which is not maxlength/minlength

Hi Tinh,

I think in this case it has taken ratio of the longest edge of an element to either its shortest edge (5.4/1.3=4.2), which is the Element Quality Calculation for HyperMesh.
