There is a maximum of 12 meteorological files that you can use in one hysplit run. However, if you have more than 12 files you can concatenate them to get a lower number.
For instance if your files are weekly files try concatenating them with the cat command (linux) or type command (windows):
linux:
rm file.month
cat file1 > file.month
cat file2 >> file.month
cat file3 >> file.month
cat file4 >> file.month
cat file5 >> file.month\

windows:
del file.month
type file1 > file.month
type file2 >> file.month
type file3 >> file.month
type file4 >> file.month
type file5 >> file.month

Thanks for your kindly attention.
I concatenate weekly gdas file of one year and now there are 12 gdas file, every month one file. When I set to run, it is written that calculation started but nothing is happened.

Start trying with only the first month. You might not have enough memory in your machine to handle the data.

I used a system with 26 GB free memory but it is same as past with 6 GB free memory and the full message is:

MGMIN set to MAX for meteorology grid: 360
configuration corrected, continuing ...
calculation started ... please be patient

Could you please try using a shorter time period in the meteorological files (say 3 months concatenated) ?
Also, could you please send me your CONTROL file?

I used a high performance computer and it has worked. As you mentioned the problem was the machine to handle the data.
Thanks so much.

I also want to concatenate multiple metorologiacal data files for faster HYSPLIT computation. Could you concatenate multiple ARL files in R?

If R has a function that is similar to the cat command in linux it should work.
