The DNSlab simulation software is a tool for design and analysis of porous structures for technical applications, especially in the field of filtration and adsorption. The 3D models of the porous structures are generated or imported by DNSlab, e.g. from tomography data. By methods of image analysis, computational fluid dynamics (CFD) and by modeling of particle collisions (discrete element method, DEM), amongst others porosity, permeability, filtration efficiency, filter cake build-up and backwashing, adsorption loading and breakthrough curves can be determined for the porous structures.

The DNSlab software provides all functions which are needed to prepare and visualize the 3D pore structure models, conducting the analyses and simulations and to evaluate and visualize the simulation results. The software can be used with a simple office PC as well as on high performance parallel computers.
