Dear Sir/Madam
I would like to prepare the input files of Modflow (PM5.1)
externally (by another application). The input files are
*.con,*.htc,*.lea and so on.

It's done now, but a problem has occured. In short, Modflow doesn't
look at my input files - bas.dat, bcf.dat and etc. I found out that
I should "regenerate input files" before running modflow.
This may be done by ticking the relative checkbox in run dialog,
while running modflow manually.
1- Is there any way to enforce Modflow to regenerate input files
automatically? (a switch, a preferences or ...)
2- If not, what are the format of these files. (Fortunately they are
text files).

Sincerely,
