Involving complex material behaviour, moving free surfaces and fluid-structure interfaces, computational modelling of self compacting concrete (SCC) flow is a comprehensive and time consuming task. The complexity and required computation time are additionally increased when simulating casting of reinforced sections, where each single reinforcement bar is taken into account. In order to deal with this issue, an innovative approach of treating a reinforcement zone as a porous medium (PM) is proposed. The presented model is based on Computational Fluid Dynamics (CFD), coupling a single-phase flow model for SCC and a continuum macroscopic model for porous medium.
