What's the best suitable area element type like 182,and 183 quadrilateral and triangle for analysis of 2D FE modeling results, beams in ANSYS APDL?

08 January 2021 1 9K Report

I want to analysis of 2D FE modelling beams cantilever/simple support in ANSYS, then compare it with exact solutions (elementary) such as deflection or stresses, however what element types (solid 182 or 183) in ANSYS Mechanical APDL are the best and appropriate? While the results will be close?

Alexey Beskopylny

Dear Hoshang Hayder !

This is not a matter of rectangular or triangular elements, but of the geometry of the area of meshing. Both elements work well when they strive for regular shapes: an equilateral triangle or square. And as a result of deformation, they do not change the aspect ratio much.
