<div style="word-wrap:break-word">Hello,
<div><br>
</div>
<div>I have an issue trying to modify an .msh file. </div>
<div>I wrote a code to generate the .geo file needed to mesh a 2D symmetric geometry. The.geo file generates only the y positive part of the geometry and I would like to work on the .msh file to create the y negative part.</div>
<div><br>
</div>
<div>For one half of the geometry I used to have:</div>
<div><br>
</div>
<div>number of nodes= <i>N.</i></div>
<div>number of elements= <i>M</i></div>
<div><i><br>
</i></div>
<div>I added N nodes in order to get 2N nodes, where the line for <i>node(N+1) </i>
is:</div>
<div><br>
</div>
<div><i>(node(N)+1)<span class="x_Apple-tab-span" style="white-space:pre"> </span>
x(1)<span class="x_Apple-tab-span" style="white-space:pre"> </span>y(1)*-1<span class="x_Apple-tab-span" style="white-space:pre">
</span>z(1)</i></div>
<div><br>
</div>
<div>and elements in order to get 2M elements where the line for the <i>element(M+1)
</i>is:</div>
<div><br>
</div>
<div>(element(M)+1)<span class="x_Apple-tab-span" style="white-space:pre"> </span>
elm-type(1)<span class="x_Apple-tab-span" style="white-space:pre"> </span>tag1(1)<span class="x_Apple-tab-span" style="white-space:pre">
</span>tag2(1)<span class="x_Apple-tab-span" style="white-space:pre"> </span>tag3(1)<span class="x_Apple-tab-span" style="white-space:pre">
</span>node1(1)+N<span class="x_Apple-tab-span" style="white-space:pre"> </span>node1(1)+N <span class="x_Apple-tab-span" style="white-space:pre">
</span>[…]<span class="x_Apple-tab-span" style="white-space:pre"> </span> <span class="x_Apple-tab-span" style="white-space:pre">
</span>nodek(1)+N<span class="x_Apple-tab-span" style="white-space:pre"> </span><span class="x_Apple-tab-span" style="white-space:pre"></span></div>
<div><br>
</div>
<div>But I got the following error: </div>
<div><br>
</div>
<div><i>Info : Vertex numbering is dense</i></div>
<div><i>Info : 92676 elements</i></div>
<div><i>Error : Error loading 'complete.msh'</i></div>
<div> </div>
<div>I attach the file for the only y positive geometry (oneHalf.geo; oneHalf.msh) and the file for the complete geometry (complete.msh) </div>
<div><br>
</div>
<div></div>

<div></div>

</div>
<div>How can I solve this problem? </div>
<div>This is meant to be part of my PhD thesis and I'm really stuck with that…Any help would be really really appreciated!!!!</div>
