t doesn’t take a pair of rose-coloured glasses to visualise this scenario: imagine you’re an aerodynamics engineer and you’re scanning a 3D simulation of your latest concept plane. You pan, zoom and otherwise manipulate the simulation that visualises airflow around the wings and fuselage. The simulation is pixilated and highly compute-intensive, and yet you’re viewing and manipulating it on a three- year-old laptop. What’s more, several of your colleagues are on a conference call with you, and they’re manipulating those same pixels in the same session from multiple locations using typical office PCs and even tablets. This scenario is a reality.That’s because an integrated solution consisting of HPC workload management software and visualisation software is doing for 3D simulation workloads what Software as a Service did for 2D applications: keeping

Converse Part Engineering’s Converse package provides a coupling between FEM solvers for injection moulding simulation and mechanical simulation. A mapping of anisotropic part properties such as fibre orientations and residual stresses, as well as a mapping of scalars like pressures, temperatures, heat transfer coefficients, wall thicknesses and shrinkage/warpage, is possible. Converse enables the consideration of the anisotropic mechanical behaviour


of injection-moulded, short-fibre- reinforced plastics parts in FE analysis. Part stiffness as well as failure can be predicted more accurately; conventional isotropic approaches do not consider the influences of fibres. Using the pressure-mapping


capability, an assessment of mould deformations, such as core shifts and inserts during the filling phase, can be made. www.part-gmbh.de

applications and data together on the server side where they can be accessed simultaneously by multiple PCs, thin clients and mobile devices. Visualisation workload optimisation couldn’t arrive sooner. That’s because it’s not unusual for 3D simulations to top out at 50 gigabytes or more. They’re getting bigger every year and management issues are following suit. Workstations are becoming obsolete faster than ever before and, of course, licensing, troubleshooting, patching and updating requirements at widely dispersed offices and desks are costly, time-consuming hassles. Upfront workstation costs also continue to be a key concern. Instead of having expensive hot, loud, underutilised workstations taking up space under desks, it makes sense to have 3D CAD/CAE and other scientific visualisation applications and data housed on shared virtualisation

clusters. Users get the full power of a high-end machine – as if it’s under their desks – while GPUs and other high- performance compute resources are shared by multiple sessions. Compute capabilities can also be ‘right-sized’ on the fly, and utilisation can be maximised. Rather than clogging networks by transferring source data for full workloads, this approach minimises bandwidth use. Support, updating and replacement of hardware and software are more efficient, less costly processes that do not affect users nearly as much as when those processes are completed at individuals’ desks. By keeping data sets closer to the centralised resources, you can also minimise security risks. To read the full article, visit www. scientific-computing.com

Autodesk 123D Design


Autodesk 123D Design, a 3D modelling tool that enables users to create a digital model and then 3D print or fabricate their idea on the iPad, Mac, PC or via their web browser, has been released. Using natural interactions for creation and editing, users can design without the need to learn complex CAD concepts. Autodesk 123D Design provides base


shapes and example models that help move past a blank screen and into the design. By using natural interactions to add objects to the canvas and assemble parts together, users can create 3D-printable designs. The Autodesk 123D Design App is available from the App Store on iPad or at www.itunes.com/appstore. www.autodesk.com
