Screenshots below show how the load is setup; however I fail to visualize in my head how this load acts on the structure. This is a cell periodicity study that does representetive volume element and periodic boundary conditions for microstructure, and I have been told its supposed to be uniaxial compression, but I fail to see how the model below give uniaxial compression:
Picture below shows hydrostatic and uniaxial compression from a related paper, but I think in the setup above there is only uniaxial compression. From COMSOL's website: "A number of load groups will be created under Global Definitions. They are collected in a group named Load Groups for Cell Periodicity. The load groups correspond to unit loads along different axes."
