The MESSAGE.001 file begins with the below text. I notice from looking at this that the PARDUMP file is designated by .001 (and .002, .003, .004 in the others), but the PARINIT file is not. So, it makes be believe they are not being read in properly by each processor. However, I did try the same run...

I'm not sure exactly what you mean by renaming the files. My steps to run a simulation include running the first multiprocessor run (say for 6 hours with 06Z GFS and 4 processors) and getting 4 output files (PARDUMP.001, PARDUMP.002, PARDUMP.003, and PARDUMP.004). These I usually combine with the pa...

I have set it to output every hour because of how I create my images.

ndump = 1,
ncycl = 1,

I can get it to work fine using one processor (hycs_std) but the multiprocessor run (hycm_std) fails to ingest the PARINIT file.

Yes, the correct input and output files are set in the SETUP file as:

pinpf = 'PARINIT',
poutf = 'PARDUMP',

I am having some problems running a multiprocessor volcanic ash run while also reading a particle input file (PARINIT). I am using the command: ../exec/run_mpi.sh 4 hysm_std The simulation *appears* to run correctly, but after creating an image from the output it is obvious that there were no partic...

Has anyone written or experimented with writing a particle file to GRIB converter (i.e. par2grib.f)?

How is the location of the red regression line shown in the particle cross section plot determined?

I have been attempting to convert the binary concentration file (cdump) to netcdf format with the ../cmaq/conc2cdf tool. The tool appears to run correctly, but when I open the netcdf file the 'conc' variable has all zeros. I know there is data in this variable because the other conversion tools (con...
