"Weband be more stable due to the symmetry restraints. If there are two planes of symmetry, then you can build a quarter symmetry model: Quarter symmetry: B B/4, E E/4, so S S/16, C C/64, p =1⁄4 which you would expect to run at least 64 times faster. Figure two shows a part having quarter symmetry geometry. " - Fea symmetry

WebSymmetric boundary conditions are often applied to minimize the size of the FEA model, hence simulation time. Owning to the symmetrical geometry of the corroded riser pipe being studied, the pipe can be effectively simplified and modelled as a quarter symmetry structure, as shown in Figure 9.2. Web1.18.8.1 RVEs. An RVE is a volume of the material of a size large enough so that any volume of an increased size will be equally representative. Apparently, for computational efficiency, one will be naturally interested in the minimum size of the RVE.
