It would be wonderful if a tool for FoamToTecplot is available

hjasak · September 22, 2005, 10:02

You are missing the fvCFD.H header - in foam-1.2 it lives in:

cfdTools/general/lnInclude

which is different from previous versions. Change Make/options file and all will be welll.

Enjoy,

Hrv

francois · September 22, 2005, 10:23

Tanks Hrvoje it works !

I'm new to OpenFOAM, I build it on tru64 this morning ... so I'm not already ok with it.

panara · February 21, 2006, 14:12

Dear all,

I am using foamToTecplot in a multizone configuration. I modified foamToTecplot in order to process only one subzone and it works in Foam 1.1

When I am using the 1.2 version it doesn't work.

It seems it cannot find the region fields in the time directories.

I modified the following line as follows:

IOobjectList objects(mesh,runTime.timeName(),"region1")

in

IOobjectList objects(mesh,runTime.timeName()/"region1/")

and works just for the first 200 time steps then for the other 100 time steps it doesn't work anymore...!!

The timesteps directory have all the same structure:

time/region1/p T U rho time

Any suggestions?

mattijs · February 23, 2006, 05:10

There should be no limit on the number of time directories.

Did you try printing the names of your ioobjects?

Pout<< objects.names() << endl;

mattijs · February 23, 2006, 06:02

Check your code very carefully.
Check your filenames very carefully. No spaces in them?
Run valgrind.
Put some printing in Unix.C::readDir

panara · February 23, 2006, 12:49

Here you are..

this is the first error that valgrind has found:

==12589==

and this a list of the source where the error should be..

168
169 if (i <= 0 || operator[](i) == '/')
170 {
171 return word::null;
172 }
173 else

Could it be due to the bug in Debian binutils (see tread 'assembler messages when compiling on AMD64') ?

Thanks for your feed back,

Daniele

mattijs · February 23, 2006, 14:40

I cannot replicate this. I created a case with >300 times and U,p in each of them and ran foamToVTK (which works similar to your Dx converter I guess)

Can you repeat it with e.g. foamToVTK (with -mesh option to read region1)? If so send small testcase and I'll have a look at it.

hjasak · February 23, 2006, 15:04

Hi Daniele,

Did you have a trailing slash "/" on the root or case name by any chance? That would do it...

Hi

the number of tecplot variables was limited to twenty. I made it dynamic and tested it on the bed-case with OpenFOAM-1.3.
The code is attached

foamToTecplot.tgz

Markus

frank · April 2, 2006, 08:45

I have tested yours code and it works perfectly fine!
Thank Markus Hartinger's help.

Hello,

I am also a Tecplot User and would like to have access to foamToTecplot.
Is it possible to get it ?

Thanks very much to help,

Anne

anja · June 6, 2006, 07:22

Hi Anne,

you can find the foamToTecplot utility within this thread. Just go to Markus Hartingers post from May 13, 2005 and download it. But also see:
Hrvoje Jasak on Thursday, September 22, 2005.

Anja

hartinger · June 6, 2006, 07:24

download the foamToTecplot.tgz thing above and save it as such.
then
> tar xvfz foamToTecplot.tgz
> cd foamToTecplot
> wmake

markus

anne · June 6, 2006, 09:21

Thanks you very much,

I have tested it on a file and it works,

Thanks again,

Anne

anja · August 15, 2006, 05:15

Hi all,

can someone please help me with the FoamToTecplot tool?
I would like to get the magnitude of the velocity with it, and not only the single components.

Thanks a lot
Anja

hartinger · August 15, 2006, 05:33

either you create a new variable in foam and write it out
or you calculate the magnitude directly in tecplot
{magU}=sqrt(sqr({U_X}) + sqr({U_Y}) + sqr({U_Z}))

markus

anja · August 15, 2006, 05:55

I know this is not the place to ask that, but where do I have to type that in tecplot?

sorry

anja · August 15, 2006, 06:12

Sorry again for that question, I already got it.

Anja

I think that foamToTecplot could not (yet) handle polyhedrals, I mean like the cells obtained using the utility polyDualMesh. Is that right?
