Multiscale FEM analysis system embedded in ANSYS Workbench using ACT technique
Kenjiro Terada, Tohoku University | Norio Hirayama, Nihon University
Multiscale analysis based on homogenization theory is an important technique that enables to get an-isotropic material properties of non-homogeneous media without real material testing. Examples of non-homogeneous media are porous, metallographic structure, honeycomb and especially composite which is GFRP, CFRP and so on.
We have developed this analysis system and embedded in ANSYS Workbench GUI using ACT (ANSYS Customization Toolkit). The tool name is CMAS (Cybernet Multiscale Analysis System). It will be released to ANSYS user's web site this year.
In this talk, the function of developed Multiscale analysis system and some analysis examples are presented.
New developments in a database of advanced material properties for CAE use
This paper describes innovative elements in a large database of advanced material properties for metallic materials, and recently polymers, ceramics, composites, foams and other non-metallic materials, aimed at serving the global engineering community with mechanical and physical properties needed for CAE (Computer Aided Engineering) calculations and simulations.
These advanced material properties have been divided to (1) stress-strain curves, (2) formability, (3) cyclic properties, (4) fracture mechanics, and (5) creep properties. Besides collecting and consolidating information for more than 40.000 materials and 200.000 datasets from more than 2.000 references, a specific set of algorithms has also been developed for assessing properties under various experimental conditions, service temperature, and heat treatment.
The paper will provide an insight into newly developed algorithms and functionalities, such as comparing materials and their properties, material selection, and special reverse engineering identification. Also, new data export functionalities and integration possibilities with CAE tools will be presented.
CAE License Assessment: Optimizing Software Usage to Improve ROI
Advances in CAE software technology are changing the way many industries are working. Engineering companies can virtualize almost the entire go to market process using these applications. CAE, or CAx, applications allow for optimize designs, create virtual prototypes, use models for testing and get ready for production even before any physical artifact is ever built.
These innovative software tools will impact businesses in many ways: from changing their processes to rethinking their approach in managing software and IT assets. Understanding application usage patterns, constantly monitoring the efficiency in using them and developing appropriate accounting procedures for properly charge back costs to each project will be important steps in optimizing the economic efficiency and improve ROI.
In today’s session, we will focus on how you can optimize your engineering software licenses to make the most out of them. Implementing a software usage metering solution with powerful analytical capabilities you can reduce software costs, control your deployment processes, implement cost allocation based on actual usage by departments or projects and collect evidences for charging actual costs to customers.
Whether you’re managing CAE applications, usage metering allows you to provide the right software to the right person at the right time thereby optimizing your costs and improving your efficiency.
Interactive and scalable 3D visualization of large CAE models in the cloud
Andres Rodriguez-Villa, Ceetron AS | Francesco Palloni, SmartCAE srl
Over the last years, the CAE community has very slowly shifted towards cloud-based applications. In this architecture, CAE analyses are not only computed on remote servers, but they are also pre- and post-processed through web-based applications, for which visualizing and interacting with remote 3D models is a prerequisite of success and efficiency.
The major part of today cloud application use the pixel streaming approach, where the server produces images and sends them to client devices, seen as faraway screens. This approach not only has limitations that make it uncomfortable for the end user, such as low frame-rate and delays in the interaction with the model, but it requires also large bandwidth and powerful servers with dedicated CPU and GPU to perform the remote visualization.
A new approach for remote 3D visualization of CAE models is enabled by the WebGL standard, where the server still generates the display model, but instead of rendering it and sending an image, it streams it directly as a collection of textured triangles to the client, where it is rendered and displayed using the client’s CPU and GPU, with high speed and great user experience.
Progressive 3D object streaming will become the standard “any model, anywhere on any device” solution, if it succeeds in rendering large models even on clients with limited resources. This issue will be discussed in the paper, with special interest being given to current and future work at Ceetron AS on the subject.
Using simulation and analysis tools to improve the bottom line
Industry-leading companies facing increased competition, more complex designs, and shorter design cycles are finding that increased use of simulation software allows them to better achieve their product availability, quality, and profitability objectives. Join Chris Wilkes as he presents the results of a recent survey of design teams worldwide to see how they use various simulation tools to achieve their business objectives. Topics to be presented include:
• What types of simulation software are being used
• Which types offer the most benefits
• The impact on time to market
• The impact on the number of prototypes used
• The challenges to increased adoption of simulation tools
You’ll learn how others are benefiting from simulation and analysis tools while overcoming the challenges associated with their increased usage.

Supercharge your workstation by moving your workload to the cloud. Preliminary results on a marine application
Cloud computing is increasingly becoming an enabling technology also for manufacturing companies. Main advantages are the scalability on multiple resources according to loading and the high reliability of cloud computing providers. Currently, cloud computing is available through different paradigms, namely SaaS, PaaS, IaaS. On the CAE market several start-ups and ISV are proposing cloud services, while big cloud providers such as Microsoft, Amazon and Google have their own IaaS proposition.
We evaluated a CFD workload in a marine application to measure the performances of a cloud provider in terms of elapsed time and scalability. The experiment showed that use of cloud computing can reduce in a relevant way time to results thanks to an immediate and unlimited availability of concurrent CFD runs thus enabling to study the typical resistance curve in a single slot of time.
In the last part of the paper we also discuss which are the current limitations and the advantages and the opportunities of running our simulations on cloud services.

Bulk handling analysis: not only mining
All over the world mining organizations are using DEM software to evaluate their bulk material handling systems. In the last years, thanks to the introduction of parallel computation on GPUs, DEM simulation could be successfully used also in other sectors, dealing with a high number of particles to be analyzed or in the need to use realistic particle forms and (not cluster of spheres). In the presentation, the potential of DEM simulation in non-mining sectors will be outlined, showing some applications in other industrial areas.
