hi,

 

I am looking for a solution to get information about the elemental system of a specific element.

 

I know it is possible to review the elemental system. but I need detail information like origin coordinates, axis components, etc...

 

Is there any command or any method to get these data?? appreciate your help!

    You can calc them from node coordinates

    Tria: origin=n1, x=n1n2

    Quad: origin=center, x= mid ray of angle n2-O-n3

    hi Tinh,

     

    Actually, I tried that method. But it didn't work. there is something weird in system calculation in HyperView. Below is the output of my macro. there is a slight difference between my output system and the expected result. 

    This difference becomes more significant when the warpage is large

    An you adjust calculation with warpage?

     

    I think x is ok

    You need adjust z only. Can you do it?

    I am able to get the normal direction of the element, nodal coordinates, centroid coordinates. I used these values to calculate the direction for the system. The result is as above.

     

    If I need to adjust z, I don't know how much should I change, where can I find out the value for the adjustment

    Do you know how elem's normal is calculated?

    I remember there's a topic about it. Can you search it
