svMultiPhysics: a finite element-based solver for cardiovascular simulations
David Codoni, Sujal Dave, David W. Parker +10
Heart disease remains the leading cause of death in the United States, motivating extensive efforts to improve its diagnosis, treatment, and prevention. Over the past decade, compu…
Comparative analysis of resistive immersed surface and immersed boundary methods for aortic valve simulation
Han Zhao, Alexander D. Kaiser, Fanwei Kong +5
Numerical modeling of aortic valve dynamics is essential for understanding the complex fluid-structure interaction (FSI) governing valve biomechanics in health and disease. Immerse…
Open-source shape optimization for isogeometric shells using FEniCS and OpenMDAO
Han Zhao, John T. Hwang, Jiun-Shyan Chen
We present an open-source Python framework for the shape optimization of complex shell structures using isogeometric analysis (IGA). IGA seamlessly integrates computer-aided design…
Shape optimization of non-matching isogeometric shells with moving intersections
Han Zhao, John T. Hwang, J. S. Chen
While shape optimization using isogeometric shells exhibits appealing features by integrating design geometries and analysis models, challenges arise when addressing computer-aided…
