Despite the fact that iterative solution techniques are recently gaining recognition among practitioners and finding their way into commercial software arena, the current state of the art in iterative methods remains unsatisfactory in many respects. Users of large production codes such as ANSYS, NASTRAN, ALGOR, SDRC, EMRC and ANSYS often observe many “bad” cases resulting from poorly conditione...

Multiphysics simulation refers to the inclusion of multiple physical phenomena in a single computational model. This may or may not require multiple solvers. For example, a mechanical solver could be used to model stent deployment to a vessel wall, and then either a mechanical or computational fluid dynamics (CFD) solver could be used to model drug diffusion in the vessel tissue. In situations ...

Bone remodeling refers to the self-optimizing behavior of bone tissue in response to a mechanical stimulus, a natural phenomenon producing strong structures with minimal weight. This paper describes BORA, an iterative finite element method incorporated into ANSYS which simulates the biological mechanism of bone remodeling. The equations relating adaptive changes in bone density to the internal ...

This paper reports the ANSYS simulation and fabrication processes for optimising PDMS ferroelectret performance. The proposed model extends the previously published analytical models and combines this with simulation of individual void geometry. The ferroelectret material is fabricated from PDMS using 3D-printed plastic mould. Mathematic model and Ansys simulation results predict that the perfo...

Many engineering fields, including tribology and MEMS, seek to use or alter the behavior of the system at the surface or at the interface between surfaces. Thus, the topography of the surface is of great interest and must be included in finite element simulations. Four methods for generating normally distributed rough surfaces using APDL are proposed. The resulting geometry, meshes, and solutio...
