Image-Conversion Software Streamlines 3D Modelling and Analysis

A breakthrough in computer-modelling and analysis software is enabling users to process 3D scans into numerical (finite element) models. The ease and accuracy with which models can be generated have opened up a wide range of previously difficult or intractable problems to numerical analysis, including blood flow, material characterisation of nanostructural composites and patient specific implant design.

According to UK-based imaging specialist Simpleware, converting 3D images into meshes for use in finite element (FE) analysis, rapid prototyping and computational fluid dynamics software, in the past, necessitated a gross simplification of the model geometry.

Simpleware?s new ScanIP and ScanFE software products offer an advanced solution to this problem, enabling users to quickly and accurately convert any 3D dataset, such as an MRI (magnetic resonance imaging) scan, into high-quality meshes in minutes.

ScanIP provides image visualisation and processing and allows files to be exported to other manufacturing software programs. ScanFE is a mesh-generation module that creates volumetric meshes which can be exported directly to leading FE (and CFD) commercial solvers.

Philippe Young, Managing Director of Simpleware, says "ScanFE creates meshes directly instead of using intermediate computer-aided design (CAD) formats. This makes the process more robust and increases bio-fidelity. It also offers a far higher quality of simulation"

Applications include micro and nanostructural analysis of composites, assessment of medical devices, such as hip replacements; modelling of biological tissue and simulation of physiological fluid flows, including air flow in tracheotomies.

In addition to the software, Simpleware provides a range of services, including reverse engineering, biomechanical research and implant design. It will also generate meshes and perform finite element analysis under contract.
