You have to add a box around your geometry in Gmsh and define the
volume between the surfaces.<br>
For doing that, you should use a .geo file where your stl file with the
conected surfaces of your plane are defined.<br>
<br>
For instance:<br>
Merge 'yourfile.stl' ;<br>
Point(201) = {*,*,*};<br>
Point(202) = {*,*,*};<br>
Point(203) = {*,*,*};<br>
Point(204) = {*,*,*};<br>
<br>
Line(203) = {202,204};<br>
Line(204) = {204,203};<br>
Line(205) = {203,201};<br>
Line(206) = {201,202};<br>
Line Loop(207) = {203,204,205,206};<br>
Plane Surface(208) = {207};<br>
Extrude {0,***,0} { Surface{208}; }<br>
<br>
Surface Loop(1) = {1};<br>
Surface Loop(2) = {******};<br>
Volume(1) = {2,1};<br>
<br>
<br>
Where the stars should be replaced by the suitable dimensions, line
numbers and surface numbers.<br>

<br>
I must study the airflow around a car using OpenFOAM and I have my
model as a STL file.<br>
<br>
I would like to know how can I obtain a volume mesh around the car
using Gmesh. The expected results would be something like what there is
on the screenshots <a moz-do-not-send="true"
href="http://www.geuz.org/gmsh/gallery/a319_4.png">A319_1</a> and <a
moz-do-not-send="true"
href="http://www.geuz.org/gmsh/gallery/a319_2.png">A319_2</a>.<br>
<br>
Thank you for helping.<br>
<br>
