Element quality check between nastran and optistruct

Hi,
I am having a Nastran solver deck and want to run it on optistruct solver. When I see element quality criteria in Nastran , it shows max. as 0.008 but the same in Nastran shows 51.55
How these values can interpreted as both decks solvers showing different values.
Any methodology to understand this
Thank you

Warpage, min. and max. angles of tria and qaud element


When I see element quality criteria in Nastran , it shows max. as 0.008 but the same in Nastran shows 51.55
I am sorry, in Nastran it shows as 0.008 and in HM with OptiStruct profile it shows as 51.55, is that correct??


Hi Gopal,
Can you let me know which criteria are you looking at?
You have given numbers of 0.008 and 51.5, which quality parameter is it for?


You can refer this on how element quality is calculated.

Hi,
This is for warpage


Hi Gopal.
Can you share a sample model with difference in warpage between Nastran and OptiStruct?

Hi,
There is one tool in 17 version in Hyperview> Preferences>NVH utilities to understand the identification of global and local modes. It talks about setting a criteria based on percentage range for identification. I wanted to know how it is setting up this criteria
I have attached image for reference
