<p>Many thanks Tanmoy. <br>

<p>So each time load_fld is called it will load the base<br>
flow variables (I am carrying out computations for incompressible
N-S <br>
equations). What if I want to load the perturbations also from a
different<br>
file? One way that I see it is to use load_fld for the restart
file for <br>
perturbations, copy it in the perturbation variables (vxp, vyp,
vzp, prp),<br>
and then again use load_fld for the base flow file. Is there a
direct or <br>
better method for this?</p>
<p>Thank you.</p>
<p>Best wishes,<br>
Navrose.<br>

<div>Hi Navrose,<br>
<br>
</div>
You are right. Two things are important in the load_fld()
subroutine. The include file 'RESTART' and the routine
setics. So everytime a load_fld subroutine is being called,
the variable values read from the current file would be
stored in vx(i,j,k,e), vy(i,j,k,e), vz(i,j,k,e), pr, t and
so on...<br>

<p>Dear Neks,</p>
<p> I am relatively new to NEK5000. I am going through
some<br>
the .usr files that have been used previously in my
research <br>
group. I notice that in the <i>userchk</i> subroutine,
<i>load_fld </i>has been<br>
called a few times. Upon checking the <i>load_fld</i>
function in <br>
in the source code, I found that <i>setics </i>subroutine
is called at the<br>
end of <i>load_fld</i> function.</p>
<p> Does this mean that each time <i>load_fld </i>function
is called, the <i>useric</i> <br>
subroutine in the .usr file is executed? I would like to
mention that<br>
no restart file is given in the .rea file.<br>
</p>
<p>Many thanks.</p>
<p>Best regards,</p>
