Variables Specified in the INVT Namelist

INVT is specified in input file (K or boundary inputs) for toroidal rotation. Variables which have no defaults (and thus require inputs??) are printed in bold.

To turn on toroidal rotation, must set KPRFIT=3 and ICURRT=5 in namelist IN1. If no pressure data, set NPRESS=0.

BETAPW0 GAQ current density profile parameter for rotation. default = 0.0
COMEGA Constraint matrix for P', FF', and POmega' when ICURRT=5 and KCOMEGA>0, in order of P', FF', and POmega'. Defines constraint equations of the form COMEGA(1,i) x(1) + COMEGA(2,i) x(2) +...+ COMEGA(n,i) x(n) = XOMEGA(i) for i=1 to KCOMEGA, where x = [alpha^T gamma^T omega^T]^T, n = KPPCUR+KFFCUR+KWWCUR. Can scale coefficients up or down relative to nominal weights of 1 to get stronger or weaker constraint, respectively.
EMW See namelist IN1.
ENW See namelist IN1.
FWTPRW array of fitting weights for rotational data.
KCOMEGA Number of constraints for POmega' when ICURRT=5, specified through matrix COMEGA and vector XOMEGA. For both equilibrium and fitting. Default = 0.
KDOVT default = 0, not used
KPLOTP See namelist IN1.
KVTOR toroial rotation switch, must set ICURRT=5.
  • 0 = no rotation (default).
  • 1 = turn on toroidal rotation in approximate first order form.
  • 2 = include second order terms.
  • 3 = exact two-fluid form. Polynomial basis. (exponential form???)
  • 11= toroidal rotation in exact two-fluid form. Exponential form.
KWWCUR Number of rotational pressure terms, for polynomial representation KWWFNC=0 only. Default = 2
KWWFNC See namelist IN1.
KWWKNT See namelist IN1.
NOMEGAT Number of rotational frequency data points.
NPRESW
NSPLOT not used
OMEGAT Vector of length NOMEGAT specifying rotational frequencies in rad/sec. Need DMASS array.
PRESW default calculation presw(i)=dmnowomegat(i)rvtor2
PRESWB default = 0.0
ROMEGAT Vector of length NOMEGAT specifying location of rotational frequency data points
  • >0 Radius of rotational frequency data points in meters.
  • <0 Location of rotational frequency data points in normalized flux coordinate.
RPRESW default calculation (what does it mean?)
RVTOR See namelist IN1.
SBETAW See namelist IN1.
SCALEPW array of scaling factor for rotational pressure or rotational frequency. default scalepw(1)=-1.0
SIGOME Vector of length NOMEGAT specifying uncertainty in rotational frequency specified by OMEGAT.
SIGPRW default calculation sigprw(i)=abs(presw(i))sigome(i)
WCURBD See namelist IN1.
WWKNT See namelist IN1.
WWTENS See namelist IN1.
XOMEGA Constraint vector for coefficients representing P', FF', and POmega' in that order when ICURRT=5 and KCOMEGA>0. See COMEGA.
ZOMEGAT Vector of length NOMEGAT specifying z position of rotational frequency data points in meters. Value of ZOMEGAT is ignored if ROMEGAT<0.
