<div><p>Hi,</p>
<div> </div><p>There are two files:</p><p>-plane.geo is just a definition file included in extruded.geo</p><p>-extruded.geo is the 3d geometry i would like to mesh.</p>
<div> </div><p>The "extruded.geo" file is the right one, "plane.geo" is just a planar geometry, which i am then extruding to</p><p>certain z-value (height) in extruded.geo. It seems to me you were making 2d mesh, i'm trying to make 3d (extruded.geo).</p>
<div> </div><p>The plane under the electrodes is substrate (plastic, foil...) on which electrodes are actually printed. I want to calculate</p><p>how the capacity of capacitor changes when substrate is changed. So basically it should be as near as possible to electrodes,</p><p>but not on the same plane as electrodes. Now, I have placed it at -1e-6 on z-axis and electrodes are at 0.0. Then I extrude</p><p>electrodes up to 0.01mm, and substrate down to -0.06mm. I also extrude the large bottom plane so it forms a big cube - this is the</p><p>surrounding air.</p>

<div>The 3D geometry is incorrect. The volume is not closed. Here is a correct version of it.</div>
<div>Note that the mesh sizes you define produce a 3D mesh of about 9</div>
