Hi, all.
I have a question.
There are some mesh type like trias as CST, quad as Q4.
I want to generate the LST elements and I found the tap named 'First order ↔Second order'.
Deos the second order button mean the LST for trais?
Thank you!!
Can you define LST trias (shape & funtions)?
The displacement function as (u=a1+a2*x+a3*y+a4*x^2+a5*xy+a6*y^2). from pascal triangle.
That's second order disp!
I was helpful.
Thanks much!!
