This option enables postprocessing and calculating material parameters, generated from representative volume elements (RVEs). The generated output are the Young’s Moduli in the longitudinal and transversal directions, as well as the corresponding Poisson’s ratio, SLIMX values, maximum stresses, and the corresponding strains. The output is only given in the command line, but is stored within the HDF5 database.

The modeling for the RVE must follow a certain scheme, which is available in more detail in [23]. The basic approach is presented in Figure 5.4: Illustration of the RVE Model with Different Loading Conditions. With this approach, two nodal IDs are relevant for the postprocessing: NID#1 and NID#4. The arrows and respective colors in the figure indicate the loading direction and where the loadings are applied. In general, the x and y directions are interchangable. However, the z-direction must be equivalent to the z-direction in the analysis, and therefore the z-direction can not be used for postprocessing.
