Spondylolysis (SL) is a defect of the spinal vertebra, and is typically caused by stress fracture of the pars interarticularis bone of the vertebral arch. It is especially common in adolescents who over train in sporting activities. Spina bifida occulta (SBO) is a malformation of the spine where the protruding vertebral bodies are not fully formed. In this study we demonstrate the predisposition ...
Finite Element Convergence and Speed-Up Studies Using COMSOL Multiphysics and LiveLink™ for MATLAB® with Large Assembly Models
H. Pourzand, A.H. Aziz, A. Singh
Pennsylvania State University, State College, PA, USA
COMSOL Multiphysics along with its LiveLink™ for MATLAB® is used to investigate the needed number of elements and the required order of Lagrangean p element for a number of different simulation models. For this task, convergence study, speed up testing and interactive meshing is performed on a large assembly model which is also imported using the LiveLink™ for SolidWorks®. As a test bench, ...

FEMLAB has standard facilities to export models to Simulink. Normally, the standard export works well if the solvers, available in Simulink, can handle the problem. However, if a model in FEMLAB needs special solvers, for example airflow or other non-linear problems, the standard export to Simulink is often not suitable, because the standard solvers of Simulink cannot handle such a problem ...

Acoustic vibrations are studied for several objects through the application of computational and optical diagnostic techniques. Computational studies are carried out using the eigenfrequency analysis option in the COMSOL structural mechanics application mode, whereas experimental optical studies utilize real-time stroboscopic holography. The two approaches provide complementary descriptions ...

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research several different reactor constructions and impeller configurations were modelled to achieve a better ...

During the past decade reverse engineering has become a common and acceptable practice utilized by many aftermarket suppliers, and even original equipment manufacturers (OEM). This presentation focuses on the applications of multiphysics software such as COMSOL and Simpleware® in reinventing the design details and manufacturing processes of an existing part in the absence of the original design ...

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...
