Hi Andrew,
<div><br>
</div>
<div>It looks like you are trying to compile for too large a case.</div>
<div><br>
</div>
<div>Two things to look for ---</div>
<div><br>
</div>
<div>1) Use the -mcmodel=medium flag in makenek</div>
<div><br>
</div>
<div> Go to G= in makenek, uncomment, and change it to</div>
<div>
<div><br>
</div>
<div><br>
</div>
<div> G="-mcmodel=medium"</div>
<div><br>
</div>
<div>2) What is your lelt value in SIZE ? If you have (say) 100 elements and are running on 8</div>
<div> processors, you would only need </div>
<div><br>
</div>
<div> lelt=100/8 = 13 or 14</div>
<div><br>
</div>
<div> (Even numbers are preferred for byte-alignment reasons.)</div>
<div><br>
</div>
<div>You would not need lelt=100.</div>
<div><br>
</div>
<div>This change would reduce your memory footprint by 8x.</div>
<div><br>
</div>

<div>Hi all,<br>
<br>
</div>
I have a compilation issue with my example. <br>
</div>
I created a mesh 3D using n2to3 from the file w2dcyl020a.rea. I don't have any issue with compilation. Then I refined the mesh 2D using pretex and rebuilt the mesh 3D with n2to3 like before this and this time an error message occured:<br>
<br>

<br>
</div>
<div>The same issue occures if I change the parameters lx1 and lxd in SIZE-file.<br>
<br>
</div>
</div>
Does anybody have an idea on how to fix this?<br>
</div>
<div>Thank you for any help or suggestion.<br>
