Zyz sailing team started designing and manufacturing small sailing boats in 2008 to participate to Italian inter-university regattas called 1001velaCUP. During the first eight-year experience of the team, different boats have been launched, trying to optimize all different aspects that influence the final performance of a boat. R3 class rule adopted in this competition imposes geometrical and structural constrains to the design process: maximum length x beam of the boat is 4,60 x 2,10 m, while a minimum percentage weight for the hull constituted by 70% of plant-origin material is imposed.

It is a great pleasure to guest blog for ANSYS again after my post in 2014 entitled Reshaping the Future of CFD Using Mesh Morphing. We continue to increase our commitment to deliver the high-performance mesh morphing technology of RBF Morph and began our new product project at the beginning of 2014.
We presented the first industrial applications at the Automotive Simulation World Congress in Tokyo in October 2014, and officially launched the RBF Morph ACT Extension on the market at the ANSYS Italian UGM in May 2015. At the end of 2015, we posted a free version (with limited functionality) in the ANSYS App Store. Continue reading
As we all know, a frequent challenge in FEM is the evaluation of stress results, in particular with cyclic stresses. The FKM guideline “Analytical Strength Assessment of Components” describes a static strength assessment as well as a fatigue strength assessment. This guideline was developed by the Advisory Board for Engineering and Research for various applications in mechanical engineering and other sectors. Continue reading
As the year winds down, I thought I’d share some of the most read ANSYS blog posts of 2015 with you. From harmonic analysis to how germs spread when you sneeze, I hope you’ll find these choices as interesting as I did.
SPOILER ALERT: We have some REALLY cool stuff coming in 2016 that you won’t want to miss! If you haven’t subscribed to the ANSYS blog yet, please make sure you do that now.
Many structural analysis models that use shell elements consist of a large number of bodies that need to be connected together to create a valid analysis model. These structures are typically manufactured by welding, for example ship structures.
There are a number of methods that can be used in ANSYS Mechanical for creating this type of model, which requires the geometry to be meshed and connected. Continue reading
You may have read a quick blog post at Desktop Engineering about ANSYS’s electric machine simulation capabilities. Here we dive into the technical aspects and implications of thermal simulation for electric machines.
Modern electric machines are designed to meet a wide range of applications, all facing a variety of different technical challenges. They are designed to be compact with high power densities, to have integrated power electronics, to be high-speed for higher power density, and to handle harsh environments.
These challenges all have thermal implications that affect the lifetime and performance of the electric machine and power electronics, and must be balanced with cost goals. ANSYS simulation tools, Fluent and Maxwell, can be used to predict the thermal and electromagnetic performance of these systems, and can therefore be used to optimize design choices for both thermal and cost considerations while meeting all application objectives.

Many FEA applications can benefit from the ability to strategically modify a mesh during solution, in order to simulate challenging geometry distortions which otherwise cannot be solved. Unlike manual rezoning, mesh nonlinear adaptivity is completely automatic, requiring no user input during solution.
There have been a number of new and exciting workflow enhancements included in ANSYS 16.0 for those who design and analyze rotating machinery to make data transfers and simulation setup easier. Here are the top five enhancements:
1) BladeGen to BladeEditor
In ANSYS 16.0, it is now possible to load BladeGen data into BladeEditor in Workbench. Users could always link BladeGen to BladeEditor (i.e ImportBGD function) in Workbench, but to perform a LoadBGD command, it was required to go into BladeEditor and find the BladeGen file to load manually. With the Create New > Geometry feature from the BladeGen (right click menu shown below) this process is much easier now. Continue reading
ANSYS 16.0 delivers the first integrated and comprehensive multiphysics simulation environment designed for all engineers. This environment is called ANSYS AIM and it is the further realization of the ANSYS Workbench strategy to revolutionize engineering processes through Simulation Driven Product Development.
