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
PCA Engineers (www.pcaeng.co.uk) is offering a free Vista CCD app for Android phones. Last year PCA made Vista CCD available as an app for iPhones. Of course, this is the same Vista CCD that is part of the ANSYS BladeModeler toolset used in centrifugal compressor design .
Recently, I talked with Chris Robinson from PCA to find out more about the motivation for making Vista CCD into a mobile app — as well as to find out how much interest it has garnered. Continue reading
With the release of ANSYS 14.0, you now have access to some exciting new CFD models for transient rotating machinery blade row simulations.
All flows in rotating machinery are transient in nature, since the position of the rotor is a function of time. To obtain the highest fidelity solution possible,analysts today model all blades of each component and generate a solution using a transient simulation. This clearly is very time-consuming calculation. Continue reading
In reality, most fluid mechanics problems are unsteady in nature. Steady-state approximations have been used since the advent of CFD as they provide adequate accuracy in many cases while the computational demands are quite moderate compared to a full transient, unsteady simulation. Current advances in multi-core desktop workstations and accessibility to high performance computing clusters allow CFD engineers to simulate larger problems with more detailed physics than ever before. This has allowed CFD engineers to increase the fidelity of their simulations by modeling the unsteady, transient nature of the flow.
Typically when running a transient simulation, best practices would dictate use of a a steady-state simulation as an initial guess. In the past this would require you to run two separate simulations, one steady state and one transient. In ANSYS CFX software, it is now possible to do both in a single simulation by using a multi-configuration setup.
If you have attended the ANSYS Regional Conference or have watched an ANSYS webinar you have probably seen high quality images like the one below. You may be wondering, “How did they make that?” Continue reading
