Engineer's Studio(R) Cloud service
Engineer's Studio(R) is an analysis program with Finite Element Method(FEM), developed in-house from pre-processing, calculation engine, to post-processing. This program allows various analysis including static analysis, dynamic analysis, and eigen value analysis. It supports for material nonlinear models and geometric nonlinear models. The structural analysis using beam elements, fiber elements, and plate elements can be performed.

For this time, we have launched "Engineer's Studio(R) Cloud Service" where the main calculation is supported by FOCUS Supercomputer(*1). This allows the scale for analysis to be enlarged and the time taken for analysis to be reduced in Engineer's Studio(R).
In this service, the data is automatically linked with FOCUS supercomputer by creating and registering them via the Internet. The final result data is scheduled to be taken via web application, saved in a medium and sent to the customers according to the situation.
As the platform of FOCUS supercomputer is Linux, the transfer is currently in progress. The algorithm of main process will be same as Windows version when the service starts, however, we will develop the optimized algorithm for FOCUS supercomputer to improve the performance. Please look forward it!

Analysis support service supercomputer option
This is the analysis support service using computation processing capable by supercomputer. The stable analysis can be performed by its high-speed and parallel processing for the models which cannot be analyzed or it takes time for it by using the ordinary compute.

The following two services are scheduled to be provided.

Analysis support service"Supercomputer option"
Supercomputer analysis and simulation service with wind, thermo-fluid analysis

[Analysis support service "Supercomputer option"] is an option of the existing Engineer's Studio(R) analysis support service. Engineer's Studio(R) supports for nonlinear plate elements. The problems such as calculation time or memory consumption are sometimes occurred in large scale models. The supercomputer allows the reduction of calculation time and the improvement of analysis accuracy by supporting precise model analysis.

acceleration in Engineer's Studio(R) 

In the analysis of 300 seconds (30,000 steps at intervals of 1/100 seconds), which was measured in the 2011off the Pacific coast of Tohoku Earthquake, known for "K-NET Tsukidate(MYG004)" opened in Kyoshin network( K-NET), NIED, the computation time is reduced using supercomputer. Moreover, as the seismic waveform which was measured in the subsequent aftershock is also opened in that network, a number of step analysis (More than 50,000 steps) can be rapidly performed with consideration of effect of main shock and aftershock.

"Supercomputer analysis and simulation service with wind, thermo-fluid analysis" is the analysis and simulation support service using general-purpose fluid analysis tool "OpenFOAM". "OpenFOAM" is developed by CFD and distributed as free and open source under General Public License of GNU. It allows the simulation of complex fluid flow including turbulence and heat transfer.

With this service, the advanced analysis environment with supercomputer is provided to many users who do not have available environment by the access to supercomputer via FORUM8's server. In addition, "Engineer's Studio(R) Cloud service" will be also provided so that every user can directly use supercomputer in cloud environment. Please try to use this service.

VR-Studio(R) Noise simulation option
Noise simulation option of VR-Studio(R) version is introduced in this issue in succession to "UC-win/Road noise simulation option"in the previous issue.

Difference from UC-win/Road version
The features are almost same as UC-win/Road version. Besides, VR-Studio(R) version allows the use of large scale models of VR-Studio(R) as well as performing the analysis process by supercomputer. These features are especially helpful for the process of large scale models. In some cases, especially for small scale data, the efficiency may be down as data files are required to be converted between preprocessor-analysis process and analysis process-postprocessor.

Data entry process of the sound source arrangement, sound receiving surface settings, analysis condition parameters settings is performed in VR-Studio(R).

Analysis process
The reflection and transmission on ground surface and model surface are considered by setting the sound path.(The information that the judgment of diffraction is performed described in the article of "UC-win/Road Noise simulation option" in the previous issue is incorrect. The diffraction is not considered.)
In the analysis process, the data can be separately processed between sound source and sound path. The parallel computation is executed in supercomputer using this feature to process large scale date efficiently in VR-Studio(R) version.

In the result data display, the sound pressure level is displayed in contour in VR-Studio(R).
