<div>Hi Kamal,</div>
<div><br>
</div>
If you use one of the nek scripts in tools/scripts (e.g., nek, nekb, nekmpi, nekbmpi, etc.), the
<div>path issues should be resolved for you. That's the normal approach. I believe some of this </div>
<div>is outlined in the "quick start" section of the manual.</div>

<div>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>

Hi JC, <br>
<br>
Thanks for the reply<br>
<br>
The parameters are positive <br>
0.00000 p064 =1 --> perturbation restart<br>
1.00000 p065 #iofiles (eg, 0 or 64); <0 --> sep. dirs<br>
6.00000 p066 output : <0=ascii, else binary<br>
6.00000 p067 restart: <0=ascii, else binary<br>
<br>
Regards,<br>
Kamal <br>

<div>Hi Kamal,<br>
<br>
Check out the parameters 64 or 65 in your .rea file. It is very likely that it is set to -4 instead of a positive number.<br>
<br>
</div>
Cheers,<br>

Hello Neks,<br>
<br>
I tried to restart my simulation from a previous output *.f file but it failed<br>
<br>
I set the restart option in *.rea to 1 and added the file name.<br>
<br>
Could some please tell me what might be the possible cause for this ?<br>
