Heterogeneous porous scaffold generation in trivariate B-spline solid with triply periodic minimal surface in the parametric domain
Chuanfeng Hu, Hongwei Lin
A porous scaffold is a three-dimensional network structure composed of a large number of pores, and triply periodic minimal surfaces (TPMSs) are one of conventional tools for desig…

Gregory Solid Construction for Polyhedral Volume Parameterization by Sparse Optimization
Chuanfeng Hu, Hongwei Lin
In isogeometric analysis, it is frequently required to handle the geometric models enclosed by four-sided or non-four-sided boundary patches, such as trimmed surfaces. In this pape…

Constructing Trivariate B-splines with Positive Jacobian by Pillow Operation and Geometric Iterative Fitting
Hongwei Lin, Hao Huang, Chuanfeng Hu
The advent of isogeometric analysis has prompted a need for methods to generate Trivariate B-spline Solids (TBS) with positive Jacobian. However, it is difficult to guarantee a pos…
