Generation and electrical simulation of carbon fibers virtual material: a parallel approach

Purpose – This paper aims to present a parallel way to generate carbon fibers virtual materials and then solve electrical problem for homogenization on conductivity tensor of the material. Design/methodology/approach – A splitting of the domain in different cells is performed before parallel generation and assembly. Two strategies are studied, with or without communication between the cells. Findings – The two methods show excellent speed-up and are in agreement with reference results for large- scale domain, even though one of the strategy has limitations for small domain with a deviation of the conductivity. Originality/value – Three-dimensional generation of carbon fibers virtual material stays rarely presented in literature, and the proposed method can easily be declined in a parallel way.
