A generic 3-dimensional system to mimic trabecular bone surface adaptation.

The paper presents the structure optimizing system based on surface remodelling. The grounds for algorithm formulation are given by the bone remodelling phenomenon leading to optimization of trabecular network in the bone. The assumptions, algorithms and limitations of the own mesh generator Cosmoprojector are described. Unlike other approaches, the system is able to mimic real bone evolution including tissue consolidation and separation. The article presents a closed system consisting of finite element mesh generation, decision criteria for structure adaptation and finite element analysis in parallel environment. It also provides some computation results obtained by using specially designed software.
