Hi Foamers,

I'm trying to programm a new format writer for surface sampling. I explain my self:

To output the pressure and the face centers for example on a surface, one uses sampleDict and putting the surfaceFormat as raw or vtk....
So wanting to write a new format and output vaues as pressure, normal of the faces, en cellcenters...in a format which will be read in a homemade sofware. So a saw the the writers are in :
src/sampling/sampledsurface/.../writers.

So should a make a copy in my USER_DIR and modify one of the write format accordingly and how can I tell the SampleDict to tanke into account my new format writer; and to read the writeType.

If someone can help me I will very appreciate.

Thank very much.

Hi Kossivi,

you have to perform two different actions.

First thing is:

1) make a copy of the whole $FOAM_SRC/sampling folder into your own user space
2) take a look to $FOAM_SRC/sampling/Make. There you have "files" and "options"
3) you are mainly interested in $FOAM_SRC/sampling/Make/files. Here you find the list of files you want to be compiled into (see last line) the sampling library.
4) what you want is to compile your own library, let's say "libmySampling" to be added to your user library folder, $FOAM_USER_LIBBIN, so edit the last line to be

LIB = $(FOAM_USER_LIBBIN)/libmySampling

Second modification to be done regards the sampling utility ($FOAM_APP/applications/utilities/postProcessing/sampling/sample)

1) copy the folder to your user space
2) here you find the Make folder, which contains the same files.
3) Here "files" is lot easier than the previous in that you compile just one application, and you may want to customize it, let say

mySample.C // remember to edit the filename accordingly

EXE = $(FOAM_USER_APPBIN)/mySample

4) in the "options" file you have at line 14 the

-lsampling

which tell the application to use the standard sampling library. What you have to do is to replace it with your edited library

-L$(FOAM_USER_LIBBIN) \
-lmySampling \

where the "-L" flag informs the compiler on where to find your customized library.

Hope this helps,
Damiano

Hi Damiano,
Thanks for your help

I have done as you indicated, and every compile very well. I compile first the my sampling and the utility in the application.
So to see if it works, I write something in the raw writer to output but it doesn't work. It seems that mine is not taken into account. Here are the folders as modified according to your advice, if you can have a look

Thanks

If you can provide a test case and the code you're testing, it would make it a lot easier for anyone to help you.
Otherwise, it will take a considerable amount of time to try and replicate the same structure you're using, which makes it less likely anyone will have enough free time to assist you in this.

Hi wyldckat,

Sorry for my late replying. My src/sampling folder even compressed is to heavy to load on the site. May be there is a way to not exceed 97.0 KB ? The same for my case file.

And thanks for your help

Best,

Hi Kossivi,

Sorry for the really late reply. I had this post of yours on my to-do list and only today did I finally manage to take a quick look into this

The problem was that in the file "sample/Make/options" you were still using the original source code path for the sampling library:

-I$(LIB_SRC)/sampling/lnInclude

This means that the linker would automatically look for the respective "libsampling.so" library.

As for making it more compact, you should have run this command:

wclean all

inside the folder of the source code for your library and your application. This would have deleted the intermediate files that are occupying so much space in the package.

Best regards,
Bruno
