<p>Dear Neks,</p>
<p><br>
</p>
<p>I'm doing some data processing for my simulations in nek5000. I found for some elements, however, the coordinates are not exactly as specified. For example, I have an element whose vertices are as follows.<br>
</p>
<p><br>
</p>
<p> ELEMENT 195 [ 1m] GROUP 0<br>
0.000000E+00 -0.130526E+00 -0.129129E+00 0.000000E+00<br>
0.100000E+01 0.991445E+00 0.979179E+00 0.987876E+00 <br>
0.000000E+00 0.000000E+00 0.000000E+00 0.000000E+00<br>
0.000000E+00 -0.130526E+00 -0.129129E+00 0.000000E+00<br>
0.100000E+01 0.991445E+00 0.979179E+00 0.987876E+00<br>
0.263158E+00 0.263158E+00 0.263158E+00 0.263158E+00</p>
<p><br>
</p>
<p>When I used the following code to print the coordinates for this element, I got the values below.</p>
<p><br>
</p>
<p> do e=1,nelv<br>
eg = lglel(e)<br>
if(eg .eq. 195) then<br>
write(*,*) xm1(1,1,1,e),ym1(1,1,1,e),zm1(1,1,1,e)<br>
write(*,*) cbc(1:6,e,1)<br>
end if<br>
end do</p>
<p><br>
</p>
<p> <span style="color: rgb(255, 0, 0);"> 7.500381456730263E-017</span> 1.00000000000000 0.000000000000000E+000 <br>
0.000000000000000E+000 <br>
W E E E P E</p>
<p><br>
</p>
<p>Is there any reason why the x coordinate for the first element vertex is not exactly 0.0e0? Hope someone can help. Thank you very much.</p>
<p><br>
</p>
<p>Best regards,<br>
