PaperGeo generates virtual paper structures and geometric models using realistic cellulose fibers, created through random structures or fiber-laydown simulation. It includes binder-addition and filler models useful for papermaking (papermaking felts) and filtration. For material characterization, the description states that FiberGeo geometries combine with GeoDict modules such as PoroDict, ConductoDict, FlowDict, ElastoDict, DiffuDict and FilterDict to calculate pore-size distribution, flow resistivity (permeability/pressure drop), effective thermal/electrical conductivity, elasticity, diffusion, filtration efficiency and capacity. Listed topics include cellulose-fiber creation and cellulose-paper models.
