Abstract This research proposed a bimodal porosity structure type providing the ability to individually form evenly distributed pores of two separated sizes. A method of generating structures parametrically was provided, and a process-oriented program was developed outputting diagrams and coordinates. Iterations of tessellation module, causing geometrical self-resemblance, were further discussed from porosity, fractal dimension, lacunarity and specific surface area aspects. Technical routes were introduced for building 3D model files of large complexity in common industrial software’s object-oriented application programming interface and applications in permeability or electrochemistry simulations.
