	Currently, we do not consider cell-centered schemes for geomechanics. In case this is to be integrated, one would have to rethink the structure of e.g. the elastic volume variables and what quantities they store that are necessary for flux/stress evaluation. In the porous medium flow context we define permeabilities/thermal conductivities etc. in the volume variables and then do the harmonic average at scvf integration points during flux calculation. However, for the box scheme one could evaluate the parameters required for flux computations directly at the integration point without averaging. For compatibility reasons with cell-centered schemes, and because one can derive an expression for the harmonic average, we do not do so in the porous medium framework. For now, we choose a more FEM-like mentality in the geomechanics framework and call the parameters in the spatial parameters, required for stress calculations, for a position in the element when assembling the stress tensors. We do not store them in the volume variables! This means that in case cell-centered geomechanical models are considered in the future, both the volume variables as well as the stress tensor assembly laws have to be restructured! More...
