IA-FEMesh: An Interactive All Hexahedral Mesh Generator for Discrete Anatomic Closed Surfaces

The broad objective of our software, IA-FEMesh is to aid patient-specific finite element (FE) model development. Patient-specific models hold the potential to enable surgeons to plan care using objective analysis-based tools. Thus, they can better evaluate alternate surgical protocols and treatments, thereby contributing to improved surgical outcome. Our previous efforts were focused on projection techniques specific to the geometry under consideration [1]. The current meshing technique is the generalization of projection techniques that builds upon a multi-block approach, with considerable attention given to incorporating interactive tools to ease the model development process, thereby creating a user friendly approach to anatomic modeling.
