DSM Somos introduces innovative software to produce reduced-density, structural stereolithography parts

DSM Somos recently announced that it will introduce a new software application allowing Stereolithography (SL) users to create lightweight prototypes having enhanced structural integrity.

Based on patented technology from the Milwaukee School of Engineering (MSOE), TetraShell hollow-build software will use MSOE’s TetraLattice technology to facilitate the manufacture of hollow stereolithography parts with variable skin thicknesses, supported by a patented and proprietary TetraLattice support structure. Potential application areas include investment casting patterns; reduced-density metal-clad composite structures; and lightweight large, thick-sectioned parts.

“Until now, hollow-build SL software has been restricted primarily to investment casting pattern applications,” says DSM Somos product development manager Brian Bauman. “The TetraShell software will allow SL part builders to widely vary wall thickness, as well as to adjust support parameters — and consequently opens doors previously closed to SL because of cost or weight considerations. Due to overall reduction of mass, the TetraShell hollow-build style will create considerable material savings for customers with bulky parts, while at the same time increasing part accuracy.”

The TetraShell software is a proprietary DSM Somos application module supported by Materialise’s Magics software and can easily be used on all current SL equipment. Beta testing is now underway, with widespread availability of the software in conjunction with Somos resins expected by year end.

CAD/CAM gets easier to learn

VX Corporation, specializing in CAD/CAM for consumer products, molds, and machining, announced the release of its new Show-n-Tell communication tool at IMTS 2008. Show-n-Tell is built into VX CAD/CAM for on-screen step-by-step lessons and to automate design review and markup as a 3D Markup tool.

The Show-n-Tell tutorial is launched by loading a VX file. Users can step back and forth with a click of a button, and all instructions are on screen — eliminating the need to flip back to a video or hold a book open. 3D models, showing the expected result, can be rotated and zoomed, giving the user better feedback and understanding. Users work at their own pace, not that of an instructor, so no one gets left behind. VX allows the user to save the Show-n-Tell tutorial session and reload it at a later date. Future tutorials will cover parametric and open shape modeling, sketching, assembly, drafting, 2X and 3XCAM, automated hole drilling, importing and healing, part splitting, electrodes, direct editing, morphing, surfacing, and reverse engineering.

MapleSim is new physical modeling “landmark” from Maplesoft

Physical modeling, or physics-based modeling, is the process of modeling the dynamic behavior of a system mathematically. Traditionally, this task required significant manual effort to derive equations and manipulate them into a form that could be used by signal-flow simulation tools that employ a block-diagram paradigm. The block diagrams are more complex, harder to produce, and do not resemble the original system representation.

With the cutting-edge physical modeling techniques in MapleSim, users can re-create a system diagram on a screen using compact and intuitive components that represent a physical model, making it easier to build and understand. MapleSim has more than 500 components from over 10 domains such as electrical, mechanical, control design, and thermal, organized into easy-to-navigate palettes.

Calculations for coupled electromagnetic and thermal simulations

The newest releases of MagNet and ThermNet are now available. ThermNet now supports coupling with Magnet’s new core loss calculation method that computes the hysteresis plus the anomalous and eddy current losses in both 2D and 3D. In a simulation, the advanced core loss calculation algorithm for eddy currents takes different harmonics into account and, for hysteresis loss, it takes into account the minor loops.

ThermNet and MagNet are now available for PCs running Microsoft Windows 2000, XP, and Vista.

Industrial-strength fluid flow and heat transfer sim

In this latest major software release, CFdesign v10 focuses on further shortening the learning curve for first-timers while adding industrial-strength problem-solving capabilities, including cavitating flow prediction and thermo-electric cooler analysis, to the engineering desktop.

“We focused on the total user experience from a first-timer’s perspective,” says Blue Ridge president Ed Williams. “CFdesign v10 is about democratizing fluid flow and heat transfer simulation. An engineer with limited or no previous engineering analysis experience can achieve extensive flow and thermal design studies in a fraction of the time it would take most CFD experts. By knocking down the intimidation-factor, we believe v10 makes it easier for companies to move CFD further upstream in the design process.”

Automatic, high-quality meshing tools increase productivity

ANSYS has released version 5.0 of its TGrid advanced mesh generation software. TGrid technology is a specialized pre-processor for fluid flow analysis. It is used to create large unstructured tetrahedral and hex-core meshes for complex geometry. The software is utilized heavily in large-scale automotive and aerospace applications, in which advanced meshing techniques are required for the computational analysis of fluid flow.

With this release, a new tetrahedral meshing algorithm, combining the speed of Delaunay and the quality of an advancing front, has been added to the TGrid meshing arsenal. This new technology, in conjunction with an advanced initialization scheme and several quality-enhancing tools, leads to improved accuracy of the fluid flow analysis. In addition, enhanced prism layer operations now include fully automatic proximity handling to support highly complex geometry. Finally, a new cavity re-meshing module allows users to swiftly replace parts and components without re-meshing the full model.
