Hello, I am very new to CFD and simulations, I am trying to simulate the power output of a kaplan hydro turbine. I have made the geometry, but when I try to mesh it, after 15 minutes it fails. Is there any function in TCAE that I can use to check the mesh, I think it might not be water tight, but I don't know where. Also, the setup check passes without errors.

If you need any more information, please let me know.

Thank you in advance.

Hello,

I tried to run the benchmark cases NACA0012 and now I am at TCAE module. I have noticed that the running time of TCAE is long and I want to accelerate it but I haven't found places to set the number of processors. Is  that means the module cannot be computed in parallel? By the way, no my CPU utilization is low but memory is full. 

Thanks for help.

Hello everyone,


I have questions about the calculation of circumferential angles circA by TCAE.


I have understood that, if a surface is oriented in the radial direction, circA on this surface will be the angle between the tangent and the velocity in the radial/tangential plane. According to graphical representation of the manual, circA shoud be positiv when the projection of the velocity in the radial/tangential plane points out (of the cylinder in the picture), and negativ when it points in.


Let's imagine that we are on a surface radially oriented where some back flow occurs and that the absolute velocity has a circA > 90° when there is no back-flow. In most of the cells of the surface, circA points out of the cylinder (90° < circA < 180°), but when back-flow occurs, circA points in the cylinder (-180° < circA < -90°). Thus, there are positiv and negativ values of circA at the same time, isn't it ? Therefore, because the circA are either > 90° or < -90°, in the in the interfaces-final.csv file in simulationRun1/TCFD/stationary/postProcessing/surfaceName/0/ folder, it seems to me that surface averaged value of circA is distorted.

I had this reflection because I find particularly high values of circA on some surfaces of my simulations.

Could someone confirm my interpretation ? Or explain me why it isn't true ?

Besides, does someone know how to visualize circA angles on Paraview after a calculation ?


Thanks in advance !

TCAE module selection buttons have disappeared. How to restore them?

Thanks in advance.

Evidently I've clobbered my TCAE installation because the module selection buttons are now missing. Re-installing TCAE had no effect. How to restore them? Thanks in advance.

Hello sir

i had gone through your webinars and various papers. recently i had read your published information regarding <TCAE-CFDSUPPORT-ACOUSTIC-BENCHMARK-PROPELLER-DJI9450> . I want to try simulation on same propeller can you please provide me cad model for dji9450 propeller that you had used in Ur simulation.

 THANK YOU

What is your recommended tool flow from Solidworks to TCAE that preserves surface names (inlet, outlet, walls etc) ?

My understanding is that unfortunately Solidworks does not preserve surface names when exporting the model as an STL file and exporting surfaces as separate STL files will produce non-conformal vertices.

Does one need to go through a third-party mesher ? I believe the Solidworks .step export preserves surface names. Is the recommended tool flow to go through a package such as Salome to create separate (but conformal) stl surface meshes ?

🌪️ Centrifugal pump CFD, FEA & FSI Simulation 🌪️

Centrifugal Pump is the hidden workhorse of mankind 🚀. Pumps transport water everywhere where it is needed 💧, and water distribution networks represent one of the largest infrastructure assets of industrial society 🏗️.

The global pump market is expected to grow significantly in the coming years 📈, due to the increasing demand from various end-user sectors, especially the agriculture sector 🌾. According to a report by Fortune Business Insights, the global centrifugal pump market size was USD 29.24 billion in 2020 💰 and is projected to grow from USD 30.56 billion in 2021 to USD 45.56 billion by 2028 📊, exhibiting a CAGR of 5.9% during the forecast period from 2021–2028 📆. Another report by MarketsandMarkets estimates that the global centrifugal pump market will grow from USD 39.7 billion in 2023 to USD 51.5 billion by 2028 🌍, recording a CAGR of 5.4% during the forecast period.

The big issue is that most of the pumps are used in regimes that are far away from their best efficiency points 🤷‍♂️. In total, that leads to wasting huge amounts of electrical energy 💡 which is more than 90% of the total costs of pump ownership 💸. Take a look at how to make a comprehensive CFD, FEA & FSI Simulation of a centrifugal pump by TCAE, to optimize the centrifugal pump efficiency 🚀.
