Hi,
I've been trying to understand in detail what type of information contain the binary output files I obtain after a simulation.

I've read about .sf (25.8) and.bf (25.10) in the UG. The .s3d format I assume it refers to the 3D smoke files, although I think it is not explicitly indicated in the UG.

I don't find what the following files are for/contain. Could you give me some guidance?
.bf.bnd
.sf.bnd

Should I check smv guide? I read something about dump.f9 but I cannot find this file in my directories.

Moreover, I think that the number of 4 digits in the filename refers to the mesh. Am I right? What does the second number (two digits) refer to? 

Thank you very much.

the .bnd files contain min and max values at each output time.  smokeview uses this to compute color indices (number between ( 0 and 255) to color data

time min_val max_val

we use run length encoding to compress 3d smoke data.  the .s3d.sz files contain information about the size of uncompressed and compressed smoke data at each time step .   smokeview uses this to allocate memory and to read in data

time uncompressed size, compressed size 

in both cases it is more efficient more smokeview to obtain this information by having it in an ascii text file rather than embedded and spread throughout a binary data file
