Description: Three factors relating to a finite element mesh and discretization scheme are discussed: the geometric accuracy of the node locations, the amount of warp of a quadrilateral shell element, and the directional biasing effect of similarly oriented triangular elements. These factors can have a significant effect on the accuracy of a finite element structural dynamic analysis. Two finite element models that illustrate these effects are described.
