Hello Neks,

I figured out where the error of restart fail comes from. Its because 
the code is not looking in to the working directory for the file.


In " byte.c " file I made a small change to the byte_read () function, 
instead of having the variable " name " I changed it to the path of my 
restart file
----------------------------------------------------------------------------------------------------
if (!fp)
   {
      if 
(!(fp=fopen("/home/2014012/jpeixi01/neksamples/eddy/eddy_uv0.f00012","rb")))
      {
         printf("%s\n",name);
         printf("byte_read() :: fopen failure2!\n");
         *ierr=1;
         return;
      }
      flag=READ;
   }
-----------------------------------------------------------------------------------------------------

this worked for me.

Now I would like to know why is the code not looking into the working 
directory, If so where do I change it to overcome this problem so that I 
don't have to change the path every single time.


Thanks a lot,
BOW
