<font face="Helvetica, Arial, sans-serif">Hi!<br>
You had some little mistakes in your .geo file. When you define a<br>
point, you have to give 4 real numbers, the last one being the local
size<br>
of the elements. What is weird is that you did not got an error message
<br>
from Gmsh.... I personnaly got one when trying to define such points...<br>
Anyway, here is what your file should look like :<br>
<br>
lc=0.1;<br>
// two points for an arc<br>
Point(1) = {0,0,-2.0,lc};<br>
Point(2) = {0,-2.0,0.0,lc};<br>
<br>
//center of the ball<br>
Point(4) = {0.0,0.0,0.0,lc};<br>
Circle(1) = {1,4,2};<br>
<br>
// i want to extrude Circle 1 of an angle Pi/2 around the axis Oz<br>
Extrude Line {1,{0,0,1},{0,0,0},Pi/2};<br>
<br>
