| 44 | * \brief Currently, we do not consider cell-centered schemes for geomechanics. | ||
| 45 | * In case this is to be integrated, one would have to rethink the structure | ||
| 46 | * of e.g. the elastic volume variables and what quantities they store that | ||
| 47 | * are necessary for flux/stress evaluation. In the porous medium flow context we | ||
| 48 | * define permeabilities/thermal conductivities etc. in the volume variables | ||
| 49 | * and then do the harmonic average at scvf integration points during flux calculation. | ||
| 50 | * However, for the box scheme one could evaluate the parameters required for flux | ||
| 51 | * computations directly at the integration point without averaging. For compatibility | ||
| 52 | * reasons with cell-centered schemes, and because one can derive an expression for the | ||
| 53 | * harmonic average, we do not do so in the porous medium framework. For now, we choose | ||
| 54 | * a more FEM-like mentality in the geomechanics framework and call the parameters in the | ||
| 55 | * spatial parameters, required for stress calculations, for a position in the element | ||
| 56 | * when assembling the stress tensors. We do not store them in the volume variables! This | ||
| 57 | * means that in case cell-centered geomechanical models are considered in the future, both | ||
| 58 | * the volume variables as well as the stress tensor assembly laws have to be restructured! | ||
