Simpleware and COMSOL Announce Partnership

Simpleware Ltd. and COMSOL Inc. announced at the COMSOL Users Conference 2007 in Grenoble a partnership agreement to provide an export interface from Simpleware's world-leading 3D image-based meshing software +ScanFE™ to COMSOL Multiphysics® 3.4, the industry's foremost multiphysics simulation environment. The +ScanFE interface enables COMSOL users to directly import high-quality meshes generated from MRI, CT, and MicroCT scan data into COMSOL Multiphysics 3.4 for modelling and simulation without requiring re-meshing or pre-processing.

Introduction to Systems Biology

How does the cell know when to produce a protein? Why does it produce this protein? How does it produce this protein so accurately, in transcription, timing, and concentration? It is amazing that the cell functions as precisely as it needs to in response to various stimuli. What is more amazing is that the cell's actions are a result of stochastic processes.

Biomechanics Calls for Papers: Materials Research Society - Fall 2007 Meeting

(cross-post to Biomch-L )

Two symposia solicit papers on biomechanics topics for the upcoming Materials Research Society meeting, November 26-30, 2007, Boston,  MA.  Short-form abstracts are due 20 June, 2007.

An overview of bio-mechanical models for bones and related topics

Hi everyone!

I'm looking for a good comprehencive overview about bio-mechanics and numerical simulation in

bio-mechanics. I'm mainly interested in the following topics:

-- mathematical models for bone simulation

-- contact problems and corresponding models (e.g., bone-prosthesis models, etc.)

-- corresponding numerics/simulations

and corresponding state-of-the-art.

Thanks in advance!

North American Workshop on Applications of the Physics of Porous Media

The 7th North American Workshop on Applications of the Physics of Porous Media will be held in Puerto Vallarta, Mexico, November 2-6, 2007. This will be the 7th biennial meeting of researchers around the world who are interested in the phenomena associated with physics of fluid flow and deformation in porous media and its applications to a broad range of basic roblems encountered in geophysics, geomechanics, medical physics, and condensed matter physics.

BRAIN TEMPERATURE AND INTRACRANIAL PRESSURE – A QUANTITATIVE BIOLOGICAL-THERMAL-MECHANICAL PERSPECTIVE

The present paper studies the effect of intracranial temperature (ICT) change on intracranial pressure (ICP). Thermal and mechanical effects were analyzed using a 3D finite element model of the human head.

Effects of Head Size and Morphology on Dynamic Responses to Impact Loading

Head responses subjected to impact loading are studied using the finite element method. The dynamic responses of the stress, strain, strain energy density and the intracranial pressure govern the intracranial tissues and skull material failures, and therefore, the traumatic injuries.

BIOMECHANICAL STUDY OF GOLF BALL IMPACT ON CHILD’S HEAD USING THE FINITE ELEMENT METHOD

Head traumatic injury due to the impact of a flying golf ball is one of the severest injuries sustained on a golf course. This paper presents numerical simulation results based on the finite element (FE) method to investigate head injuries in children due to impacts by flying golf balls.

The comings and goings in a cell

Update 23 March 2007.  This wonderful educational video has now been removed from YouTube because it violates copyright.  What a pity!

Andre of Biocurious has just pointed out this terrific animation of the dynamics inside a cell. It brings many pages of textbook to life. Delightful. I've just followed Teng Li's instruction to embed the YouTube video below.

Analysis of a golf ball hitting the eye

Purpose of the Study
Computer models of the human eye were constructed for the purposes of studying interactions with foreign bodies.

  • Based on in vivo patient data
  • Multi-part model
  • Mixed volumetric and surface meshes
  • Automated generation of contact surfaces

Scan and Segmentation in ScanIP
High resolution in vivo MRI scans of a 29 year old Caucasian female was obtained using both a surface and a head coil on a Philips Gyroscan 1.5 Tesla imager. The following structures were segmented from the 3D data set by a Physician: the globe and optic nerve, the bony orbit, the eyelids and facial soft tissues, the extra-ocular muscles.

Mesh Generation in +ScanFE
A number of finite element models were generated based on the segmented image data. Each structure was meshed with mixed hexahedral and tetrahedral elements. The contact surfaces are particularly robust as the master and slave contact faces are paired - contact structures were exported as volumetric meshes and as surface meshes as required. For this application, the bony orbit was modelled as a rigid structure defined by surface shell elements rather than as a volumetric mesh thereby providing some computational saving.

FE Analysis in LS-DYNA
An analysis of a golf ball hitting the eye was carried out to demonstrate the robustness of the model for simulation purposes, as well as to demonstrate the remarkable sophistication of biological models which can now be generated based on in vivo data. This case study was developed in collaboration with Naomi Green at ARUP, Solihull, UK.

Adaptation of arteries to pressure changes

Arteries are living organs that can remodel themself in response to stress changes. Arterial remodeling is a big topic and this paper shows only a tip of the iceberg.
