Hello I got an error message when trying to do a 3D mesh of the following code.
The error message told me to send information of my error to this adress.

r=7.25;

//tjocklek av finare mesh
f=1;

//distans mellan bränslestavar
d=3.825;

//antal cellager för finmesh
fl=3;

//fjärdedels båge (cellager)
fb=5;

//3/4 Pi båge (cellager)

//antal cellager för block
bl=3;

//för extrude

//antal cellager på längden
