Abstract

The authors developed an adaptive finite element algorithm for modeling the highly heterogeneous 3D domains often encountered in biomedical applications. The method differs from traditional approaches in that no explicit description is required of the boundaries between objects with dissimilar material properties. This allows an efficient and completely automated generation of subject-specific models from classified medical images
