Centerline and blockstructure for fast structured mesh generation

Abstract In contrast to unstructured meshes, structured meshes yield faster simulation results for bio-medical simulations, but are very time-consuming create. A preprocessing step in the generation of is manual construction a blockstructure approximating vessel. Here, we present an automatic centerline calculation and reduce user effort time mesh generation. The detected as points between opposite faces. Based on centerline, cross sections determined which approximates vessel automatically generated. detection does not require input with more than 195,000 vertices processed less 160 seconds. presented compared generated by widely used vmtk tool. centerlines similar, small differences occur at bifurcation aneurysm.
