A problem encountered while using the "srun" for distributed parallelism with the TFCD case on a high performance computing platform.

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 computin...

[TCAE-23.03v1] CAEProcessor command mode: kill -SIGINT PID not working

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

[TCAE-23.03v1] /TCAE/etc/CAEProcessorDefaults.tcae: setting defaults values

Hello everyone,
I'm having a problem with a value (Cp: specific heat) that I want to set as default in all my TCAE projects. For that I modified the file TCAE-23.03v1/TCAE/etc/CAEProcessorDefaults.tcae by adding
Cp "1800_J/(kg.K)"
When I create a new TCAE project, the v...

Parametric Axial Fan designed in OpenVSP

Hello,


I would like to present my current project for further experiments with TCAE and TOPT.


It is a parametric axial fan created in the OpenVSP free parametric CAD primarily used for aviation purposes. It allows controlling the geometry with pre-programmed parameters and their further linking. It can also be controlled by external scripts. All thes...

Number of Components Limits

Hello,


Is there a possibility to increase the number of CFD components that we can put within the simulation.

Currently the limits seems to be set at 10 components.


Thanks in advance for your response.

Yours,

Fluid dynamics informed machine learning by Gabe Weymouth

The combination of fluid dynamics and machine learning has become an area of increasing interest in recent years, as researchers look for ways to use machine learning techniques to improve our understanding of fluid dynamics and make better predictions about fluid behavior.


One way that machine learning can be applied to fluid dynamics is through the use of data-driven models....
