Hi everyone !

It's my first post here and I have a few questions on post-processing's manipulations and on variables' meaning :

1) How can I get the surface areas of the components' interfaces on TCAE (Paraview interface) or in the calculation case's folders ?

2) The TCAE user manual indicate that here are 2circumferential angles : the axial and the radial circumferential angles. To analyse my data, I need to extract the radial circumferential angle. However, withe the option 'calculateAngles on' in .../stationary/system/interfaces.fun, I only get one circumferential angle : circAng. How can I know which one is it (radial or axial) ? Or a mix of both ?

3) How is the mass flow rate calculated on the interfaces, with the absolute speed or with the flow speed (the radial speed for the mass flow at the outlet of a centrifugal impeller for example) ?

I hope someone will be able to help me on these topics... Thanks in advance !

Kaplan Turbine CFD, FEA, FSI, and Optimization

CFD (Computational Fluid Dynamics), FEA (Finite Element Analysis), and FSI (Fluid-Structure Interaction) simulations are powerful tools for analyzing the performance of hydro turbines.

CFD simulations can be used to predict the fluid flow and pressure patterns in and around a hydro turbine, including the water flows through the turbine blades, the pressure drop across the turbine, and the efficiency of the turbine under different operating conditions.

FEA simulations can be used to analyze the structural integrity of the hydro turbine and its components, including the blades, shafts, and bearings. These simulations can help to identify potential stress and fatigue issues in the turbine and to optimize the design of the turbine for better performance and durability.

FSI simulations can be used to simulate the interaction between the fluid flow and the turbine's structure, which is especially important in hydro turbines because of the large loads and pressures that are generated by the water flow. FSI simulations can help to understand how the turbine's structure deforms and how it affects the fluid flow, as well as how the fluid flow affects the turbine's structure.

Altogether, CFD, FEA, and FSI simulations can provide a comprehensive analysis of a hydro turbine's performance, including its efficiency, structural integrity, and durability, which can be used to optimize its design and improve its performance.

Centrifugal fan design & simulation, an overview of complex virtual prototyping of centrifugal fans using Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and Fluid-Structure Interaction (FSI). These technologies offer engineers a comprehensive toolset to design, optimize, and analyze the performance, structural integrity, and reliability of centrifugal fans.

With the use of CFD, engineers can simulate and analyze the fluid flow inside the fan, allowing them to optimize the geometry, blade angles, and other design parameters for maximum efficiency and performance. Additionally, FEA can be used to analyze the structural integrity of the fan, ensuring it can withstand the forces and stresses generated by the fluid flow. FSI combines the analysis of fluid flow and structural response, allowing engineers to understand how the fan structure will deform under the influence of fluid forces.

The combination of these technologies enables engineers to simulate and optimize a variety of scenarios, including different operating conditions, such as varying fan speeds, flow rates, and fluid properties. This allows engineers to refine the design of the fan before building a physical prototype, reducing development costs and improving the overall performance and reliability of the fan.

In this overview, we will explore the benefits of using CFD, FEA, and FSI to design and optimize centrifugal fans. We will also cover the basic principles of each technology and how they can be used in combination to simulate and analyze the performance and structural integrity of centrifugal fans. So, let's dive in and explore the world of virtual prototyping of centrifugal fans using CFD, FEA, and FSI!

Beam Ball FS Benchmark. 

TCAE is a simulation environment for comprehensive CFD, FEA + FSI, and optimization in a single workflow. Take a look at the study of the Beam-Ball FSI benchmark. This study is unique, because the exact solution can be evaluated analytically, and the analytical solution can be compared with the simulation results. The particular goal of this study is to investigate and compare the deformation of a beam with a ball at its end, stressed by the airflow.

Hello! Everyone, 

I was looking at a video about acoustics and there I saw that the virtual microphone data is converted into an audio file which I thought was incredible. Please if anyone knows how this can be done in OpenFOAM or TCAE? 

Thank You

We are currently running ubuntu v18.04 and TCAE version v23.03.  We are now adding a second server node to start building an HPC 2 node cluster.  We are thinking to upgrade ubuntu at this time. Is ubuntu v22.04 supported with TCAE v23.03, or should we stay with ubuntu v20.04 as this is the most current version that is mentioned in the TCAE software manual.

Hi everyone!

I want to call a tensorflow neural network while running TCAE redSolver.

Is there any relevant tutorial available?

Thank you!

Hello everyone !

First I have to mention that I’m a total newbie with these program, for installation I just follow tutorial on youtube.
And to know how to use it I was following this tutorial
But when I’m at the 7:30 Paraview insult me with this :

ERROR: In vtkOpenFOAMReader.cxx, line 11320

Do you have any idea that could save me ?
Thanks in advance

Hi, I am trying to use TCFD for distributed computing on the high performance computing platform of my own department. This platform uses slurm as the job scheduling system. When I use the command: `srun -n 127 -N 10 -p normal redDyMSolver -rotatingVelocityFields -parallel`, the error shown in the picture occurs.

I am not sure if it is a problem with the high performance computing platform or with TCFD. Can anyone help me?

Or is there any other way for me to perform distributed computing with TCFD on the high performance computing platform?

Our team at CFDSUPPORT believes that success in engineering projects is the result of a combination of focus, skills, experience, patience, and dedication, rather than quick actions in a rush. To ensure accuracy, CFDSUPPORT regularly tracks and compares CFD results with real-world physical measurements. An example of our commitment to accuracy is the Centrifugal Compressor Benchmark project. This project was a collaboration between CFDSUPPORT and compressor manufacturer CZ a.s. The goal of the benchmark validation was to assess the accuracy of the TCFD software and compare its simulation results with actual compressor measurement data. By continuously striving for accuracy, CFDSUPPORT and its partners are able to deliver more reliable and trustworthy results for their clients.
