Hi together,

Please note that CAESES can be utilized as an OpenFOAM GUI (Graphical User Interface).

 

There are free academic versions of the CAESES pro edition for students and PhD students as well as trial licenses with flexible time frames. There are also special editions for small companies, start-ups and freelancers.

 

Compared to other tools in the market, CAESES is good at automation, i.e. if you already have an existing OpenFOAM setup and you want to analyze design variants of your product, then CAESES might be a perfect choice. Especially, if geometry variation plays a major role. In contrast to that, a tool such as HELYX-OS might be a better choice e.g. if you would like to set up an OpenFOAM case from scratch.

 

Here are some CAESES-specific offers:

  • Conveniently configure and manipulate template files (e.g. controlDict or any other ASCII file) in the GUI
  • Change your geometry design and trigger OpenFOAM with a single mouse-click for analysis (i.e. streamline your design process / automation)
  • Use your individual result values such as pressure loss or homogeneity for an objective function in design studies and shape optimizations
  • Postprocess your simulation data (streamlines, contour plots etc)

Here is a video that shows some of the features in CAESES.

Cheers
Joerg

Hey Joerg

 

This may be due to my lack of understanding of Ubuntu and OpenFOAM, but I have been trying to run the Ahmed Body sample.

The part I have been struggling with is pointing CAESES to an OpenFOAM executable.

I understood that there was no single OpenFOAM program, but that it is a library of utlitlies and solvers?

 

Do you think you could give me a hint as to what to do next, where to find the OpenFOAM executable or do I point it to the solver executable?

 

cheers

 

James

Thanks for your help Matthias

 

Could not get it to run, below I have copied and pasted the output of the console.

Hey Carsten

 

I found i found the stdouterroroutput.redirect file and have copied it below.

 

Seems like it cant find where OpenFOAM library is located?

Hi James,

 

It seems to be a problem of OpenFOAM variable resolving!

 

Maybe you didn't setup your OpenFOAM environment before starting CAESES-FFW.

 

To do that:

- you can modify the CAESES-FFW.sh start script and add the following lines in the header (not in the first line, you need the shebang!)

- you can modify your  ~/.bashrc to have the environment settings in all your Terminals(note: you have to run the CAESES-FFW out of a terminal).

- you can  modify your  ~/.profile to have the environment settings for all your applications (even from the Desktop Icon, if you created one)

(-> please read for more details or find a man page for your distribution)

export FOAM_INST_DIR=/data/app/OpenFOAM
foamDotFile=$FOAM_INST_DIR/OpenFOAM-2.1.1/etc/bashrc
[ -f $foamDotFile ] && . $foamDotFile

With that setup you will always "source" (load) the required OpenFOAM environment before starting CAESES-FFW.

 

Otherwise the line in the script "Allrun" would not be succesful.

. $WM_PROJECT_DIR/bin/tools/RunFunctions

more installation help could be found here:

Hello

 

Im havin problen with openfoam connector.

I have workin isntall of openfoam 221, currently im using helyx os with it, but free version is limited and does not have modelling capabilities.

So CAESES would be berfect for my use, but Im having problem with connectin openfoam, im trying to run ahmedboby sample but im getting this error:

How to get started to solve what is going wrong?

Hey Jussi,

 

Sorry for the late reply.

 

I assume you have read the project documentation and done this:

 

In order to initialize OpenFOAM, source your OpenFOAM dot-file before starting the CAESES/FFW from

the terminal or modify the loaction of the dot-file in the prepared stringparameter or the Allrun Script itself. 

To start the computation go to SoftwareConnector and start the application with a right click on the central element and then "Run".

 

You can also take a look in the Taskmonitor (you can find it on the right side of the CAESES window)

post-41-0-16771500-1422887102_thumb.png

It contains the console output of the allrun script and openfoam.

 

You can also find two tutorials with an OpenFOAM integration.

Documentation > Tutorials > Integration

Does this help?

Hi,
I am having the same problem (I think). I have spent a week trying to solve this by myself but I really can't see the problem.

Below is th copied text from the stdouterroroutput.redirect file:

 

/home/alasdair/OpenFOAM/AH81_OpenFOAM_Propeller/manual_results/baseline/Runner//Allrun: 5: .: Can't open /home/alasdair/OpenFOAM/OpenFOAM-2.3.1/bin/tools/.RunFunctions

 

ANy help would be appreciated.

 

Regards.

Hi Alasdair,

 

the first lines of your Allrun script should look like:

 

#!/bin/sh
cd ${0%/*} || exit 1 # run from this directory

chmod +x Allrun.pre
. /home/carsten/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc

# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

I just realized that the source command does not work, instead you should use the dot :

use

. /home/carsten/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc

instead of

source /home/carsten/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc

I hope this works for you

Hi Carsten,

thaks for replying. I have tried a few variations of the allrun script, currently it looks like this:

 

 

#!/bin/sh

cd ${0%/*} || exit 1 # run from this directory

 

# Source tutorial run functions

. /home/OpenFOAM/OpenFOAM-2.3.1/bin/tools/RunFunctions

 

chmod +x Allrun.pre

 

wmUNSET

. /home/OpenFOAM/OpenFOAM-2.3.1/etc/bashrc

touch case.foam

 

 

./Allrun.pre

 

runApplication decomposePar

 

runParallel `getApplication` 4

 

runApplication reconstructPar

 

This has changed the error message in stdouterroroutput.redirect to:

 

[Captured output from application /home/alasdair/OpenFOAM/AH81_OpenFOAM_Propeller/manual_results/baseline/Runner//Allrun]

/home/alasdair/OpenFOAM/AH81_OpenFOAM_Propeller/manual_results/baseline/Runner//Allrun: 5: .: Can't open /home/OpenFOAM/OpenFOAM-2.3.1/bin/tools/RunFunctions

 

I am a bit stuck.

 

Regards,


Alasdair.

Hi Carsten, I have done that, and that changes the error file to:

 

/home/alasdair/OpenFOAM/AH81_OpenFOAM_Propeller/manual_results/baseline/Runner//Allrun: 4: /home/alasdair/OpenFOAM/AH81_OpenFOAM_Propeller/manual_results/baseline/Runner//Allrun: wmUNSET: not found

Hi Carsten,

 

I tried changing the file path as suggested and removin wmUNSET, error file reads:

Hi Carsten, I have already done that as I saw the post when I forst started trying to get this to work - please see below copy paste from my CAESES -FFW file:

 

export FOAM_INST_DIR=/data/app/OpenFOAM
foamDotFile=$FOAM_INST_DIR/OpenFOAM-2.3.1/etc/bashrc
[ -f $foamDotFile ] && . $foamDotFile

Alasdair.
