2nd order means LST, right?

Altair Forum User · May 2019

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.
