<p style="margin:1.2em 0px!important">I guess you have to define theses points as <code style="font-style:inherit;font-variant:inherit;font-weight:inherit;font-stretch:inherit;font-size:inherit;line-height:inherit;font-family:inherit;margin:0px 0.15em;padding:0px 0.15em;white-space:pre-wrap;border:1px solid rgb(234,234,234);border-radius:3px;display:inline;background-color:rgb(248,248,248)">Physical Points</code>, isn’t it ?</p>

I hope that you one of you might have time to point me in the right direction...<br><div>
<p>I have a box:</p>
<pre style="margin-left:40px"><code><font size="1">box_size = 50;
lb = 10.;
Point(1) = {-box_size/2, -box_size/2, -box_size/2, lb};
Point(2) = {box_size/2, -box_size/2, -box_size/2, lb};
Point(3) = {box_size/2, box_size/2, -box_size/2, lb};
Point(4) = {-box_size/2, box_size/2, -box_size/2, lb};
Line(1) = {1, 2};
Line(2) = {2, 3};
Line(3) = {3, 4};
Line(4) = {4, 1};
Line Loop(5) = {1, 2, 3, 4};
Plane Surface(6) = {5};
Extrude {0, 0, box_size} {
Surface{6};
}</font>
</code></pre>
<p>This works quite well and gmsh is happy to (3D) mesh it.</p><p>The problem is that I would to ensure that certain points inside the box
are node points. So my question is, how do I ensure that points, like
these</p>
<pre style="margin-left:40px"><code><font size="1">lc = 10;
Point(5) = {7.150548, 1.000000, -6.990684, lc};
Point(6) = {-4.438894, 1.000000, -8.960816, lc};
Point(7) = {-9.893936, 1.000000, 1.452595, lc};
Point(8) = {-1.675894, 1.000000, 9.858569, lc};
Point(9) = {8.858176, 1.000000, 4.640336, lc};
Point(10) = {1.675894, 4.750000, -9.858569, lc};
Point(11) = {-8.858176, 4.750000, -4.640336, lc};
Point(12) = {-7.150548, 4.750000, 6.990684, lc};
Point(13) = {4.438894, 4.750000, 8.960816, lc};
Point(14) = {9.893936, 4.750000, -1.452595, lc};
Point(15) = {7.150548, 8.500000, -6.990684, lc};</font>
</code></pre>
<p>are part of the mesh nodes?<br></p>
<p>The reason I need this is that I need to impose boundary conditions at these specific points.</p>
<p></p>
<p>Thank you all in advance.</p><p></p>Best wishes,<br></div><div>Julius<br><br>
