Numerical tests of formulae for volume enclosed by flux surfaces of integrable magnetic fields
David Martinez-del-Rio, Robert S. MacKay
Numerical tests of volume formulae are presented to compute efficiently the volume enclosed between flux surfaces for integrable 3D vector fields with various degrees of symmetry.…

Conefield approach to identifying regions without flux surfaces for magnetic fields
David Martinez-del-Rio, Robert S. MacKay
The conefield variant of a Converse KAM method for 3D vector fields, identifying regions through which no invariant 2-tori pass transverse to a specified direction field, is tested…
