    Hello Neks, <br>
    <br>
    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.<br>
    <br>
    <br>
    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  <br>
----------------------------------------------------------------------------------------------------<br>
    if (!fp)<br>
      {<br>
         if
(!(fp=fopen("/home/2014012/jpeixi01/neksamples/eddy/eddy_uv0.f00012","rb")))<br>
         {<br>
            printf("%s\n",name);<br>
            printf("byte_read() :: fopen failure2!\n"); <br>
            *ierr=1;<br>
            return;<br>
         }<br>
         flag=READ;<br>
      }<br>
-----------------------------------------------------------------------------------------------------<br>
    <br>
    this worked for me. <br>
    <br>
    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. <br>
    <br>
    <br>
    Thanks a lot,<br>
    BOW <br>

                          Check out the parameters 64 or 65 in your .rea
