8.4 computeRBGGE

• description: Compute generalized gradients [50] from data on a rectangular boundary [57] for use with elegant’s BGGEXP element.
• synopsis:

  computeRBGGE -yminus=filename -yplus=filename -xminus=filename -xplus=filename -normal=outputFilename [-skew=outputFilename] [-derivatives=number] [-multipoles=number] [-fundamental=number]

• switches:
  • yplus — SDDS file containing x, y, z, and By, map stored in columns for positive-y plane. If skew components are desired, file must also supply Bz. Units are meter and Tesla.
  • yminus — SDDS file containing x, y, z, and By, map stored in columns for negative-y plane. If skew components are desired, file must also supply Bz.
  • xplus — SDDS file containing x, y, z, and Bx, map stored in columns for positive-x plane. If skew components are desired, file must also supply Bz.
  • xminus — SDDS file containing x, y, z, and Bx, map stored in columns for negative-x plane. If skew components are desired, file must also supply Bz.
  • normal — Output file for normal-component generalized gradients. Supply to NORMAL_FILENAME parameter of BGGEXP.
  • skew — Output file for skew-component generalized gradients. Supply to SKEW_FILENAME parameter of BGGEXP.
  • derivatives — Number of derivatives vs z desired in output. Default: 7
  • multipoles — Number of multipoles desired in output. Default: 8
  • fundamental — Fundamental multipole of sequence. 0=none (default), 1=dipole, 2=quadrupole, etc.
