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, I tried to run the benchmarks case DJI9450 that I downloaded from CFD SUPPORT. But the  CFD calculation failed after 100 hours running and it showns that "Application redDyMsolver failed" . And there was nothing in the error log. I haven't change anything except the number of processor. Would it be OK if I run it again?

Thanks for your help.

Hello CFDSupport Team,

I am experiancing a slight problem in Paraview during simulation. Window where residuals shall be seen is a bit strange. Is this some kind of a driver problem? Do you might give me any hint where to look?

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.

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

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?

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 value of Cp is well defined at 1800 J/kg/K. However, it seems that when through the GUI I set the value to 0

and that I save, restore then check, no error is reported and I can run the simulation without any problem. That's when I looked at the TCAEproject/setup file and I was surprised to see that the heat capacity value was changed to
Cp "1004_J/(kg.K)"
This value corresponds to the air, originally set by default in the CAEProcessorDefaults.tcae configuration file.

So why my value that I set to 1800 J/kg/K was not returned ?

Hello everyone,

I have seen that it exists a new option called --apply-diff for the CAEProcessor command. The help just said that it "changes the project setting by specifying the path to the text file with TCAE configuration keywords, which are to be changed." And the example give us only

CAEProcessor --project fan --apply-diff changes.txt --save-as fan-2

But I wonder what is the information and format of this changes.txt file?

Hello everyone,

I have just installed the new version 23.03v1.

I wonder in which cases it is necessary / recommanded / relevant to enable "Use external geometries / meshes (file will not be imported into the project)" in TMESH in this new version 23.03v1 ? I have noticed that in TCAE/tutorials repertory, it is enable only when TOPT is used.

In my case I have got an already meshed geometries from FLUENT but I have seen that it is possible to both enable/disable this feature. But I have encountered some issues when it is disabled. More specificaly, sometimes, when I restore the project, one interface (inlet/outletInterface) disappear.

What do you recommend?

This is a practice exercise for one of my subjects. Currently I want to simulate this setting (automatic chicken feeder). My product frequently breaks at the arrow position. The material is PP (Polypropylene) plastic (the pipe part is steel). I want to simulate the broken position and the direction of improvement? Anyone who has a way to handle this can help me more (where should I put contacts, ..)? Thank you

Dear Team, 

I am trying to run a simulation of the FDA Benchmark Blood Pump case with TCAE. I am using my meshes that I have generated by myself (not via TMESH). 

The project case setup seems to be fine, and I get the message "Project Setup OK" upon checking. However, when I start the TCFD run, I get the following error message after a while - 

"--> FOAM FATAL IO ERROR:

Cannot open include file "C:/Users/KaranBaliga/Desktop/TCAE/GridPro Blood Pump/Fluent_Grids_GridPro/GridPro_Blood_Pump/simulationRun1/TCFD/transient/1_1/system/hi.fun" while reading dictionary "C:/Users/KaranBaliga/Desktop/TCAE/GridPro Blood Pump/Fluent_Grids_GridPro/GridPro_Blood_Pump/simulationRun1/TCFD/transient/1_1/system/controlDict/functions"

I do not know why this error occurs. Can you please help me out?

If required I can attach the case files as well. 

Thanks and Regards,

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.

Hello,

I wanted to know how to add patches to the component for which an external geometry has been imported.

Without that, I am unable to add inlet, outlet and other boundary conditions.

Dear Sirs,

I want to export a francis turbine runner geomtery to TCAE Pareview... I get always an error

"Loading inputfile "C:\Users\lenovo\Documents\resources\geometry\ft27022023.tcae"...

Required keyword "1_solid-meshInput" with 1 entries is missing in the setup file.

No path to STL file for solid component 1

Inputfile "C:\Users\lenovo\Documents\resources\geometry\ft27022023.tcae" contains invalid settings.

Failed to import surface geometry file "C:\Users\lenovo\Documents\resources\geometry\". A path to .stl or .step file expected."

Mesh is set to cfd mesh only...

anyone to help me..
