How to compress results files so that paraview can still read them
 
Hello,

I have a run that generated about 2GB of data. Is there a way for me to compress the result files, but so that paraview can still open them for display

Thanks,

Mirko

foamFormatConvert should do it for you. Just change the writeCompression entry in system/controlDict to 'compressed'. It seems to be hard-wired for ascii, but a simple switch to IOstream::BINARY should do the trick for binary output.

I think the PV3FoamReader can handle binary/compressed formats (or is that only in Takuya's native/parallel version? Can't remember).

Thank you.

Since I did not see this mentioned anywhere explicitly:

for chtMultiRegionFoam, I had to specify the -region argument in order for the fields in XYZ/region/U|T|rho|... to be processed.
