Shap3d34.dat, 34th 'shape' file for CPO3D
A torus, using the option for users equations, replaces shap3d18.
It is similar to shap3d33, but with 'a' larger and 'b' smaller, and with theta and phi both covering -pi/2 to pi/2.
See users equations for further information.
The equations, as they appear in the data file, are:
theta -1.57 1.57 name of variable number 1 and its limits
phi -1.57 1.57 name of variable number 2 and its limits
a 1 name of parameter number 3 and its fixed value
b 0.25 name of parameter number 4 and its fixed value
0 0 name of parameter number 5 and its fixed value
0 0 name of parameter number 6 and its fixed value
b*cos(theta)
(a+b*sin(theta))*cos(phi)
(a+b*sin(theta))*sin(phi)
1 1 numbers of 2 applied voltages (can be same)
10 10 numbers of subdivisions of variables 1 and 2
(The program has corrected the less accurate value that was entered for pi/2.)
