update restart.ww3 wrong by using ww3_uprstr

[jiqiyan]

I have some problems in updating restart.ww3 using ww3_uprstr.
ww3_uprstr can run normally, while the generated restart001.ww3 seem to have lots of NaN value.
as the SWH from new output file with a lot of NaN values; I don't know why.

First, the files anl.grbtxt 、ww3_uprstr.inp、 mod_def.ww3 are ready
Then,
$: cp restart058.ww3 restart.ww3
$: ww3_uprstr
$: mv restart001.ww3 restart.ww3
restart058.ww3 is the restart file which I want to update the analysis field of SWH
after these step, continue to run the WW3, the new output SWH have lots of NaN value

The algorithm to update restart file is UPD2 , the output SWHRSTR_UPD2.txt show
similar characater of analysis filed (anl.grbtxt). but the new output SWH have lots of NaN

here is my ww3_uprstr.inp
