IA-FEMesh: An open-source, interactive, multiblock approach to anatomic finite element model development

An Open Collaborative Model for Development of Finite Element Program

An open collaborative model for development of structural analysis program is presented in this paper. The main design principle of this framework is to keep the kernel flexible and extendible so that the researchers and engineers can easily incorporate new element technologies and solution strategies. The distributed element service over the Internet shows that the open collaborative model cou...

An Integrative Theoretic Approach to Open Source Software Development

A finite element approach to self-consistent field theory calculations of multiblock polymers

Self-consistent field theory (SCFT) has proven to be a powerful tool for modeling equilibrium microstructures of soft materials, particularly for multiblock polymers. A very successful approach to numerically solving the SCFT set of equations is based on using a spectral approach. While widely successful, this approach has limitations especially in the context of current technologically relevan...

Open-Source Environment for Interactive Finite Element Modeling of Optimal ICD Electrode Placement

Placement of Implantable Cardiac Defibrillator (ICD) leads in children and some adults is challenging due to anatomical factors. As a result, novel ad hoc non-transvenous implant techniques have been employed clinically. We describe an open-source subject-specific, image-based finite element modeling software environment whose long term goal is determining optimal electrode placement in special...

Mixed Finite Element Methods on Nonmatching Multiblock Grids

We consider mixed nite element methods for second order elliptic equations on non-matching multiblock grids. A mortar nite element space is introduced on the non-matching interfaces. We approximate in this mortar space the trace of the solution, and we impose weakly a continuity of ux condition. A standard mixed nite element method is used within the blocks. Optimal order convergence is shown f...
