A key challenge to finding quantitative solutions to biological problems is to model the complex 3D geometry of naturally occurring structures. Model generation often starts from serial sections from CT or MRI scans, confocal microscopy, or physical sectioning. In addition, prior to V4 of COMSOL Multiphysics®, there was a "loft" command to allow construction of 3D models from serial sections within COMSOL. However, the loft feature is not currently available in COMSOL.

A solution for building 3D structures from serial sections has been developed based on the use of the COMSOL LiveLink™ for MATLAB® module to construct lofted 3D NURBS (Non-uniform Rational B-Spline) geometries.
