I'm trying to modify the patchAverage tool, so that the calculation result will be written into a simple text file. In a simple C++ app, including

Code:
#include <iostream>
#include <fstream>
and adding the following simple code:

Code:
ofstream results;
results.open ("results.dat", ios::out | ios::app);
results<< sumField << endl;
results.close;
should do the job. Howewer, I cannot compile that tool. wmake will produce the following:
Code:
Making dependency list for source file patchAverageToFile.C
SOURCE=patchAverageToFile.C ;  g++ -m64 -Dlinux64 -DDP -Wall -Wno-strict-aliasing -Wextra -Wno-unused-parameter -Wold-style-cast -march=opteron -O3  -DNoRepository -ftemplate-depth-40 -I/home/stss2/OpenFOAM/OpenFOAM-1.5.x/src/finiteVolume/lnInclude -IlnInclude -I. -I/home/stss2/OpenFOAM/OpenFOAM-1.5.x/src/OpenFOAM/lnInclude -I/home/stss2/OpenFOAM/OpenFOAM-1.5.x/src/OSspecific/Unix/lnInclude   -fPIC -c $SOURCE -o Make/linux64GccDPOpt/patchAverageToFile.o
patchAverageToFile.C: In function ‘int main(int, char**)’:
patchAverageToFile.C:96: error: ‘ofstream’ was not declared in this scope
patchAverageToFile.C:96: error: expected `;' before ‘results’
patchAverageToFile.C:97: error: ‘results’ was not declared in this scope
patchAverageToFile.C:97: error: ‘ios’ has not been declared
patchAverageToFile.C:97: error: ‘ios’ has not been declared
make: *** [Make/linux64GccDPOpt/patchAverageToFile.o] Fehler 1
Can somebody tell me how to fix that?

Thanks, Björn

what's the object of your modified patchAverage file? the original patchAverage tool already has the ability to produce data.If you want to get a data file,you just run the tool,

just like this: patchAverage fieldName patchName > dataFileName

then you can get the data file

So I don't know your real object.If the object is just to get a data file,you can do as above,

Well, I need to parse the calculation result with another application for automated post-processing. So it would be nice to just write out the result rather than writing the whole screen output to file.

l_r_mcglashan will become famous soon enough
Try sticking 'std::' in front of ofstream, or 'using namespace std' before main.

Great, that worked, thank you very much! ofstream and ios are obviously not declared in the foam namespace.
