SusCritMat is a European Institute of Innovation & Technology (EIT) RawMaterials funded education project which develops teaching modules on critical raw materials and their sustainable management, taking into account the different perspectives as well as the entire value chain. This webinar on demand presents interesting insights on criticality and sustainability assessments, as taught in the SusCritMat modules.

Our modern way of life is deeply dependent on air travel as well as other modes of public transportation. Business people, vacationers, family members and friends are, one way or another, affected by the travel ban caused by COVID-19. Social distancing guidelines aim to minimize the spread of airborne diseases while in open spaces or large enclosed environments. But these guidelines are extremely difficult to follow when traveling on a plane, bus, subway, etc. Not only are passengers confined to a relatively small enclosed space, but the necessary ventilation systems can cause strong air currents that quickly spread the droplets from exhalation, coughing or sneezing throughout the passenger compartment. This introduces significant safety concerns as we decide whether or not to resume traveling.

So how do we protect ourselves while traveling? This is an especially difficult question for an airborne virus like SARS-CoV-2 that causes the COVID-19 disease. Understanding the flow patterns inside a passenger cabin can be used as a basis to suggest new best practices for safe air travel. To achieve this goal, Ansys computational fluid dynamics (CFD) software, Ansys Fluent, is used to model the motion of particles exhaled by a coughing passenger.

The current global pandemic caused by COVID-19 has impacted people around the world and has caused many industries to come to a halt because of the risks of transmission. Due to the way the virus is transmitted and its ability to survive on surfaces for an extended period of time, there is a strong need for ensuring proper cleaning and disinfection of frequently visited areas. This is particularly important for the transportation industry (air, rail, subway, etc.), where seating and support structures are shared among many travelers, with little possibility of avoiding contact. In order to begin re-opening these methods of transportation at scale, the public needs to have confidence that these environments are safe.

Simulation can be used to design the right UV light treatment system for each environment and for validating that sufficient doses of UV light are being delivered to ensure virus deactivation.

Typically, there are five significant losses in a motor: stator copper loss, rotor copper loss, core loss, friction-windage loss and stray losses. Among these five, the one which is least analyzed, yet very significant (about 15% of total losses of the motor) is the stray loss (SL).

In this webinar we discuss how stray losses in an induction machine can be modeled and how the models can be used to design efficient motors. 

新版本软件，各方面都会比老的版本带来全方位的提升。技术在进步，方法在革新，计算机系统也在进步，各种底层算法库，通信库，指令集，加速方式，林林总总，可以说是人类智慧在软件技术上的集合结晶。做产品研发设计，面对竞争白热化的市场，取得成功的关键就是与时间赛跑，新版本的软件，具有各方面的优势，是可以作为最先进的生产力工具，极大提升研发优势的方式。

5G 时代背景下，各行各业都面临创新升级，无疑需要借助 5G 高速航道弯道超车，实现产业的巨大成功。智慧系列场景，物联网，AI、自动驾驶、大数据运算等新兴技术的蓬勃发展，使得电子设备的形式多样，数量众多，全频带覆盖，电磁环境急剧恶化，随之带来的挑战就是要在如此复杂而恶劣的电磁环境之下，设计出依然满足电磁兼容性 EMC 认证要求的高性能产品。因此，EMC 设计是当今复杂电子产品设计中极其重要的一环。

天线是移动通信系统的重要组成部分，随着移动通信技术的发展，天线形态越来越多样化，并且技术也日趋复杂。进入 5G 时代，大规模 MIMO、波束赋形等成为关键技术，促使天线向着有源化、复杂化的方向演进。天线设计方式也需要与时俱进，采用先进的仿真手段应对复杂设计需求，满足 5G 时代天线不断提高的性能要求。

Accuracy and solution time are two of the most critical concerns in computational fluid dynamics (CFD) simulation, and both greatly depend on the characteristics of the mesh. Different types of meshing elements are needed to deliver optimal performance in resolving unique geometries and flow regimes.

Ansys is addressing this concern with the introduction of Mosaic mesh technology, which automatically connects different types of meshes with general polyhedral elements. New mesh-connecting technology has the potential to deliver exciting new combinations of meshing elements that will help meet the challenges of increasing part complexity and accuracy requirements for years to come.

In this webinar, you will learn tips and tricks for CFD meshing that are useful for generating complex geometry meshing, conjugate heat transfer (CHT) meshing, etc.

Topics include

• CFD meshing workflow for CHT
• CFD meshing tips and tricks to generate good quality mesh and geometry features capture
• Volume meshing — parallel computing

圣诞节即将来临，满眼望去各处已经充满浓浓的节日氛围了，这时候来上一杯红酒或许是节日里不错的选择。说到红酒，眼前就会浮现出将盛酒的玻璃杯轻轻旋转的熟悉画面。实际上，这个动作叫做“摇杯”，是为了让红酒与氧气充分接触，红酒杯基本上“越旋转就越容易溶入氧气”，适当地让氧气融入红酒可以激发红酒的香气，使其口感更加醇厚甘美。但凡事过犹不及，融入太多氧气就会造成过度氧化进而影响红酒的品质，导致风味受损。

所以，为了能够更加美味地品尝红酒，“如何让红酒与氧气充分接触”是关键。但是，仅凭摇晃酒杯就能让红酒融入更多氧气吗？酒杯的不同也会存在一定的差异吗？非装备党又要如何才能尽兴地品味出红酒的香醇？带着这些问题我们再次邀请Ansys日本工程师团队通过流体仿真软件Ansys Fluent用仿真数据说话！
