WORKSHOP: Image-based Simulation for Biomechanics, Materials Applications, and Reverse Engineering

This workshop is aimed at those interested in 3D reconstruction from radiology images, and in using 3D image data (as obtained from CT, Micro-CT, MRI and Ultrasound) to generate Rapid Prototyping, CAD, and Finite Element models.

Participants will learn:
•    how to generate computer models from your 3D image data
•    how to import and position CAD files in the image data
•    how to integrate with CAD Software as well as FE solvers such as Ansys, Abaqus, Comsol, LS-Dyna, etc.

Hi iMechanica-experts,

I'm working with soft tissue models of abdominal organs (e.g. liver) for surgery simulation. These models are alway constructed from segmented surface files (triangles, e.g. .stl). I'm devloping an algorithm that uses isometric quadratic tetrahedral (tet10) elements (mainly in order to reduce volume locking). Now I'd like to generate a tet10 mesh from the surface mesh.

Currently I use 3-Matic to generate linear tetrahedral meshes from the .stl files. While it is possible to just add a node on each side of the triangle to convert this tet4 mesh to tet10 (this can be done with 3-Matic) I haven't found a way to generate real isometric quadratic tetrahedral meshes.

I have a squre block and inside it there is an sphere. I want to mesh
the whole assembly. I can mesh the sphere but when i try to mesh the
squre block with the spherical hole it cant mesh and says "it cant
select the source and target face". I also tried to devide it into 8
parts. That helped me to mesh the sphere but i cant mesh the squre with
spherical hole with that too. So please anyone can help me out.

Moceon; world leading experts in high quality all hexahedral meshing, today announces the launch of their website www.moceon.com

Based on the Spatial Twist Continuum, which was discovered by the founder in 1992, a new method has been developed into a commercial level software package that is being rolled out first as a premium high quality hex meshing service.

Moceon also introduces the Cell3 concept, a revolutionary new way to describe a hex mesh with integrated morphing and smoothing capabilities. Cell3 = cells with conformal continua.

This new Cell3 definition breaks the bounds of conventional meshing paradigms by enabling interactive design based modeling.

hi 

i am doing my PhD in  "smart composites"

i am working on piezoelectric composite materails... 
i will be greatful to you if anyone can suggest me  how to model the piezoelectric materials in ANSYS.i am having some doubts in meshing and giving the voltage input to ANSYS.

if i directly glue actuator to the beam using volume glue  then i am getting problem while meshing volume as "invalid topology for mapped brick mesh". how can i glue two volumes in ansys and avoid the problem in meshing???

expecting a response ....

Regards..
