[Gmsh] Small dimension objects from CAD software - mesh generation problem

[Matija Mraovic]

Hi, 

There are two files: 

-plane.geo is just a definition file
included in extruded.geo 

-extruded.geo is the 3d geometry i would like
to mesh. 

The "extruded.geo" file is the right one, "plane.geo" is just
a planar geometry, which i am then extruding to 

certain z-value
(height) in extruded.geo. It seems to me you were making 2d mesh, i'm
trying to make 3d (extruded.geo). 

The plane under the electrodes is
substrate (plastic, foil...) on which electrodes are actually printed. I
want to calculate 

how the capacity of capacitor changes when substrate
is changed. So basically it should be as near as possible to electrodes,


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 

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 

surrounding air.


Thank you!

extremely finely meshed. I have changed it ti 1 mm.

that is drawn on the electrodes is the same as the one where the
