For the development of bioreactor systems, it is reasonable to develop working simulations, to avoid a lot \"trial-and-error\" experiments. Our research goal is the creation of functioning bone grafts for transplantation. Therefore stem cells get homogenously seeded into porous ceramic scaffolds.

To evaluate the needed parameters, like perfusion pressure or the mechanical deformation of the scaffold, we use different simulations to calculate the wanted parameters, important for future experiments. Therefor we performed fluid simulations on macroscopic and microscopic scale to predict the physical conditions and the needed stimuli for the cells in culture and to design a bioreactor.
