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

Here's the link to my project folder : https://www.dropbox.com/s/2oybdps02f1webf/eggs.zip?dl=0



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.

please i would like to know how intall OPENFOAM with window software. i have downloaded the OPENFOAM logiciel on CFDsupport link

Hello Everyone, 

I am trying to simulate, bubble formation in two fluids, oil + water. How can I calculate the mass of the bubbles, formed in each phase?

Thank you 

In CFD we generally have a problem when we encounter something that is supposed to move on its "free will". One of these problems is an unknown rotation speed of a turbomachinery rotor. Common practice is that the user prescribes flow boundary conditions for one specific case or does a full spectrum of operational conditions including rotation speed. But what if he knows an input aerodynamic or shaft torque and wants to obtain a stable rotation speed (with no acceleration)?

One way is to use the TOPT algorithm where you look for a minimum of optimization function prescribed as (target_torque - calculated_torque)^2. 

First I calculated a torque for 187 RPM. Then I set this torque to our optimization function and ran TOPT with RPMs as a parameter.

After several runs, the RPMs started to converge around the value of 187 as they should. The DIRECT algorithm was still trying other options, but got to the minimum of our function relatively quickly.

Axial Turbine Stage - test topic. Axial Turbine Stage CFD. It is hard not to be emotional when seeing an axial turbine stage CFD. The axial turbine stage was our first big CFD project made here at CFDSUPPORT. In a way, it had preset our destiny - turbomachinery simulations. Here is a little example of how now, ten years later, TCAE runs the whole complex process in one command (or click). By TCFD: https://www.cfdsupport.com/axial-turbine-cfd-simulation.html

Hello,

I am trying to add heat transfer model in MPPICFoam, however my limited knowledge in advanced openFoam could not crush it. 

Mainly I am trying to replace kinematicCloud with ThermoCloud. 

I am trying to simulate heat transfer between continuous phase and discrete particles. Can someone please provide any insights on this?

Hello,

I'm trying for the first time to use the "Add hosts" feature which, if I understand correctly, allows us to use computing cores on machines that are on the same network as ours.
So I try to add a host whose IP is for example 192.168.0.150, whose username is User1 and which has 4 cores. On my machine, for example, I want to allocate 8 cores for the calculation, i.e. a total of 12 cores. Both our machines are Linux machines.
1) I have already sent him my public authentication key id_rsa.pub so that I can connect to it without entering a password with
2) I have already installed on this machine the same version that I use of TCAE (23.03v3)
3) I also run source $HOME/TCAE/TCAE-23.03v3/OpenFOAM-dev/etc/bashrc-release on machine 192.168.0.150
However, on the GUI, the info tells me that the host is not known. What did I miss?

Thanks for your help

Hello,

What is the meaning of the option "Add volume source" in scalar (Multiphysics). Is the source volume linked to an inlet patch or can it be also inside the computation volume?

LBM, OpenCL, GPU

In this new version of TCAE 23.03v1, the command mode

echo $OPTION > $TCAEproject/cfdp-command.txt
kill -SIGINT $TCAEpid

doesn't work. I guess due to the several changes in all TCAE project repertories, the file cfdp-command.txt has also change. Probably the name, it format or it location?
