Team 194: Aerodynamic Study of Airflow around an Airfoil in the EGI Cloud

Team 194In this case study from Team 194, led by Praveen Bath, Engineering Technology Consultant in India, the incompressible air flow around an airfoil has been studied. The model setup included the geometry preparation where a selected region was modeled to represent the surrounding air volume with the airfoil profile at the center. The airfoil profile needed to be accurately modeled to capture the variation in the airflow pattern around the airfoil. The model setup was done using CFD Support’s professional OpenFOAM 3.0. The OpenFOAM software is embedded in an UberCloud Container sitting on EGI / CESNET cloud resources in Prague. The main objective of this project was to experience the ease-of-use of the UberCloud OpenFOAM software container and to evaluate HPC performance with respect to the accuracy of result prediction as well as the solution time and resource utilization.

The Democratization of CFD

Democratization-of-CFD-SchematicOver the last couple of years, and particularly following the ASSESS 2016 Congress in Maryland, Keith Hanna and Ivo Weinhold from Mentor Graphics have been debating the latest phrase to hit our Industry: the ‘democratization of CFD’. They both felt that over the last 25 years the CFD industry is not where they hoped it would be in terms of truly democratized CFD usage. In his 4-part blog about ‘The Democratization of CFD’ Keith Hanna looks at what is being said in the market about the democratization of CFD by vendors, at forums like NAFEMS and ASSESS, on CFD industry blogs, and in engineering magazine articles. The 4 parts are about the democratization of CFD with Part 1 “Mind the Gap”, Part 2 “Why is it so Difficult?”, Part 3 “Pros and Cons of Technology Solutions, and Part 4 “Boldly Going …”.

UberCloud Publishes ANSYS Compendium of Case Studies, 2012 – 2016

This document is an invaluable resource for engineers, scientists, managers and executives who believe in the strategic importance of Computing as a Service, in the Cloud. It is a collection of 18 selected case studies written by the participants of the UberCloud HPC Experiment, who used different codes from ANSYS, like Fluent, CFX, and HFSS in the cloud. Among these case studies you will unquestionably find scenarios that resonate with your own situation. You will benefit from the candid descriptions of problems encountered, problems solved, and lessons learned. Projects covered are in fields of Computer Aided Engineering (CAE), such as Computational Fluid Dynamics (CFD) and Structural Analysis (FEA).

Team 184: Spray modeling of dispensing device with ANSYS CFX in the Microsoft Azure Cloud

The 18 engineering cloud case studies are about a flash dryer, irrigation systems, wind turbines, combustion modelling, desalinization, fan performance, gas-liquid flow, geo-thermal perforation, fluttering of aircraft wings, microelectronic packaging, frontal car crash, spray modeling, engine intake manifold, airbag simulation, implantable planar antenna simulation, and more.

UberCloud Team 193: Implantable Planar Antenna Simulation with ANSYS HFSS in the OzenCloud

Team 193For this case study from Team 193 Ozen Engineering in California performed design modifications and performance tuning of a Planar Inverted F Antenna (PIFA) in the OzenCloud and studied the implantable antenna placed inside the skin tissue of an ANSYS human body model. The resonance, radiation, and Specific Absorption Rate (SAR) of implantable PIFA were evaluated. Simulations were performed with ANSYS HFSS (High-Frequency Structural Simulator) which is based on the Finite Element Method (FEM). ANSYS HFSS has been packaged in an UberCloud software container and ported to the cloud. All simulations have been performed on a 40-core Nephoscale cloud server with 256 GB RAM. These simulations were about 4 times faster than on the local 16-core desktop workstation. Read the complete case study HERE.

Overcoming Security Challenges in the Hybrid Cloud

Cloud Data-Security-370x290

Businesses are embracing the flexibility and scalability of hybrid cloud computing, where the public cloud and ancillary dedicated infrastructure converge. IDC predicts that by next year, 80 percent of organizations will be committed to hybrid cloud architectures. But many firms still struggle with cloud security management, with more than half citing security as their greatest challenge. Especially as internal departments outside of IT interact with these platforms, simple mistakes and security knowledge gaps can escalate into more serious issues. In his article Brett Moss, senior vice president and general manager at Ensono, provides  a few best practices businesses should have in place as they become more reliant on hybrid cloud platforms, such as: getting serious about ‘shadow IT'; centralizing cloud management; and prioritize data security.

Infographic on the adoption of cloud applications in manufacturing to see how your company compares

Manufacturing Cloud Infographic 2017

Do you feel stuck in the 90s, designing and launching your cutting edge products on old product management systems? Don’t fall behind. It’s time to move to the cloud. According to PropelPLM.com the adoption of enterprise cloud applications in manufacturing companies is accelerating as industry leaders look to cut overhead costs, gain visibility into important data, and engage more easily with customers. Propel, Salesforce, Rootstock, ICIX and Tavan Technologies launched a survey at the Manufacturing ISV Cloud Summit in Chicago to get a better understanding of how manufacturing companies are using enterprise cloud applications, like Salesforce, Workday and NetSuite. While Sales, Marketing, Services and IT are heavy users, the survey found that there’s a major shift underway in how engineers are adopting cloud technologies. See the very interesting Infographic which looks at cloud adoption for manufacturing, cloud benefits, cloud maturity, cloud challenges, and cloud recommendations for manufacturers:  Manufacturing: On the Cloud Frontier, HERE.

Thermal modeling on cloud-based simulation app

Team 192This CAE Cloud project from end-user Stephan Savarese of ForCES, a provider of multiphysics simulation, training and consulting services for climate, energy and science, was designed to explore how cloud HPC resources can help to speed up and enable high-performance finite element simulations carried out with COMSOL Multiphysics and COMSOL Server. The engineer’s objective was to find out how HPC cloud providers like CPU 24/7 can augment engineering organizations’ on-premise hardware to allow for more detailed and faster simulations. In his article in 3D CAD World, Bruce Jenkins from ORA Research describes the application model of an industrial fragrance extraction boiler, challenges of running simulations for days on the user’s local desktop, use of COMSOL in an UberCloud software container, the work process and implementation, benchmark results, and benefits of running these simulations in the cloud.
