Rif,
<div><br>
</div>
<div>I would try in your .usr file:</div>
<div><br>
</div>
<div> subroutine usrdat</div>
<div> :</div>
<div> :</div>
<div><br>
</div>
<div> integer e,f</div>
<div><br>
</div>
<div> nface = 2*ndim</div>
<div> do e=1,nelt</div>
<div> do f=1,nface</div>
<div> if (cbc(e,f,1).eq.'M ') cbc(e,f,1) = 'SYM'</div>
<div> enddo</div>
<div> enddo</div>
<div><br>
</div>
<div>(this is assuming that the "M" gets loaded into the first position of the 3-character</div>
<div>string cbc; you could add:</div>
<div><br>
</div>
<div> if (cbc(e,f,1).eq.' M ') cbc(e,f,1)='SYM'</div>
<div> if (cbc(e,f,1).eq.' M') cbc(e,f,1)='SYM'</div>
<div><br>
</div>
<div>if you want to cover all bases.</div>
<div><br>
</div>
<div>One important point --- "SYM" requires that the face in question to be planar with a normal</div>
<div>pointing in either X Y or Z direction... If it it pointing somewhere in between you would have</div>
<div>to run with the stress formulation.</div>

<div>Hi Neks,<br>
</div>
I have downloaded the program mshconvert file to convert my Fluent mesh to nek5000 format. It works well with normal boundary conditions like W,v and O where W is wall, v is inlet velocity and O is outlet. However, the I am unable to prescribe symmetry, SYM
as the code only takes the last letter (for this case, M). Any of you facing this problem and is there a way around this?<br>
