How do you know if you’re getting good answers?

In these days of automatic finite element mesh generators and powerful computers that can process large models efficiently, how do you know that the results being calculated are actually any good? George Laird of Predictive Engineering (a Siemens PLM channel partner) explores FEA data postprocessing in his article, “See Analysis Data’s True Colors”, published by Desktop Engineering.

Judging whether a finite element mesh is good or bad

In this article George explains how stresses are calculated and outlines various tricks that help understand and interpret the results… and to set the scene, the article starts with a quote our own head of Femap development, Mark Sherman, who says, “whenever you see a stress contour plot, just assume that it is wrong”!
