ST7-1.50.90.1 Modelling Symmetry
Many structures exhibit some degree of symmetry. This can sometimes be exploited such that only a portion of the model need be represented in FEA, reducing the time to get solutions or freeing up resources for a more refined mesh. In order to exploit this symmetry, both the geometry and loading must be symmetric.  Symmetry can be expressed as a fraction of the structure which remains once all redundant sectors are removed. / / / The resulting sector shown below is obviously much...
