Session KP01 - Poster Session III.
POSTER session, Tuesday afternoon, March 23
Exhibit Hall, GWCC
The PIES( Reiman, A.\,H., Greenside, H.\,S., Compt. Phys. Commun. 43), (1986). code has the ability to start its iteration scheme using VMEC(S. P. Hirshman, D. K. Lee, Comput. Phys. Comm. 39), 161 (1986). magnetic fields as the initial guess for its magnetic field. Using the VMEC fields as the initial guess significantly reduces the number of steps to convergence. We have recently modified PIES to be able to use the VMEC currents as the initial guess rather than the fields. This means that PIES can be used as a field line following code using coil currents and plasma current as the source function. We are hoping that this will aid us in resolving reconstruction problems that have surfaced in the design of NCSX. The results of this and other PIES applications to NCSX will be presented.
