Hello everyone,

I am working with Gmsh and quite new in it. I am trying to create a simple cylindrical tube. I successfully run the script but get a syntax error for Physical Volume. Here is the code:



************************
lc = 0.1;
D = 1;
Point(1) = {0, 0, 0, lc};
Point(2) = {D/2, 0, 0, lc};
Point(3) = {-D/2, 0, 0, lc};
Point(4) = {0, 0, D/2, lc};
Point(5) = {0, 0, -D/2, lc};

Circle(1) = {2, 1, 5};
Circle(2) = {5, 1, 3};
Circle(3) = {3, 1, 4};
Circle(4) = {4, 1, 2};

Curve Loop (1) = {1, 2, 3, 4};
Plane Surface (1) = {1};
Rotate {{0, 0, 1}, {0, 0, 0}, -Pi/4} { Surface{1}; }

Volume(1) = Extrude {Sqrt(2)/2*20*D, Sqrt(2)/2*20*D, 0} {Surface{1};}

Physical Volume (1) = {1};

Mesh 3;

Here is the error:
line 20: syntax error (Physical)
Any help is appreciated
Thank you
