Binary files: compressed or uncompressed?
 

Hello,

today I wanted to run a simulation in OF5.0, and when I change the writeFormat and compression in the controlDict, I got this warning:

I know, for example, that using compressed ASCII is much less space consuming that the uncompressed one. Does it make a difference in binary?

Thank you for your attention,
Agustin

Did you try it? :rolleyes: binary files don't compress as well as ASCII files.

Well, you could do it in OF2.3 and there was no warning at all. I know binary should be better for OpenFOAM to read the files.

So, what do you suggest? Try only binary, or compressed ascii?

Never ASCII, unless you are testing. For production runs always binary uncompressed, unless you are more pressed for space than performance.
