Hierarchical numerical modelling of porous media in SfePy

Popis výsledku v původním jazyce

Materials with different levels of porosity at different scales can be found in nature as well as in technical practice. The theory of homogenization provides a natural way of upscaling a lower level description to higher levels of porosities in a sense that effective material coefficients (stiffness, permeability, Biot coefficients etc.) at a higher level are obtained by applying homogenization to the lower level. This leads to a suitable hierarchical description of the porous medium, where all the different porosities are taken into account. However, such a description involves solving many sub-problems in complex relationships. In the contribution we discuss our method of tackling this complexity using the homogenization engine implemented in the open source finite element package SfePy.
