Input

Tomcat may take many inputs but most of them don’t need to be changed by the average user, as such they were given a “standard” value. The variables an average user might want to change are listed in Input_TestModBC and are:

  • namecase: The name of the machine

  • shortname: short name of the machine

  • N0: core density [m^-3]

  • N1: edge density [m^-3]

  • nspeci: number of species present in the plasma

  • z: species charge numbers

  • a: species mass numbers

  • concentr: species concentrations

  • ichargeneut: speci where you enforce charge neutrality (most often majority ion)

  • iforcechargeneut: boolean forcing charge neutrality computation

  • ap: minor radius [m]

  • R0: major radius [m]

  • B0: Toroidal magnetic field [T]

  • IDSHAPE,xkap,del0,delt: machine definitions, a boolean to enable D shape, kappa (elongation), Shafranov shift of the magnetic axis and triangularity

  • T0: species core temperature [eV]

  • T1: species edge temperature [eV]

  • exponn= exponential in density profile

  • expont= exponential in temperature profile

  • frek: frequency [Hz]

  • ntor: toroidal mode number

  • xleft/right: start and stop point simulation

  • xleftin/xrigthin: inner domain, between xleft and xleftin is a detailed region with high resolution solving, similar for xright and xrightin.

  • numLFS: number of elements on the LFS space inbetween xright and xrightin

  • numHFS: number of elements on the LFS space inbetween xleft and xleftin

  • zleft/right: Integration interval is from (xleft,zleft) to (xright,zright)

  • icollis= boolean to enable collisions

  • colfreq= collision frequency, per species

  • iasymp= asymptotic expansion of plasma dispersion function used or not

  • ky= wavevector in the y (Z) direction

  • IHFS: Antenna at the HFS or not
