Abstract

A computer model has been established to simulate two-dimensional arterial trees as branching systems of straight cylindrical tubes. Resistance and flow conditions in the model trees are governed by Poiseulle's law. Tree generation is performed by successively adding segments, so that certain structural and geometric constraints are fulfilled at each stage of development. In the present work, the structural characteristics of trees with 4000 terminal segments generated by constrained constructive optimization (CCO) are investigated and related to the variation of constraints and optimization criteria.
