A 3D model for growth of filamentous fungi on solid substrate, based on microscopic observations was developed and tested on macroscopic experimental data. Comparisons with previous models were performed. The specificity of solid substrate growth was taken into account in the model equations. Interest for FEMLAB users is the difficulties we had to define 3D complex structures, like polyhedra.
