Shap3d35.dat, 35th 'shape' file for CPO3D
A circular magnetic field inside a torus, to illustrate the option for a 'coiled' magnetic solenoid along an arc of a circle.
Uses the option for users equations, replaces shap3d32.
For information on the option for users equations, see users equations.
A closed magnetic field is created inside a torus, which is taken from shap3d18.
The magnetic field in each quarter is created by using 100 individual thin hoops, placed along an arc of a circle.
To see the magnetic field go to the xy view and click on contour/magnetic/vector. To remove some large fields at points near to the hoops, make the 'maximium magnitude' 0.11. The fields in the vicinity of an individual hoop can be seen by zooming.
The electrode torus is created as in shap3d34.
