Card 9 - KEEPDEL Element Deletion/Retention

This optional card defines the deletion or retention of elements and their associated data.

Parameters: KODE, N1, T1, T2

KODE

KODE is the code KEEPDEL (or 15)

N1

N1 is an element number, or a group name.

T1

T1 is another element number, or 0. T1 must be 0 if N1 is a group name.

T2

T2 may be:

  • DELETE (or -1): All references to elements N1 through T1 will be deleted by the DATACH module, including Card 5 elements on INPF, the XCOND and XCAP Cards, and all references from files VUFF, MODLF, and MODLCF. N1 = T1 = 0 defaults to all elements.
  • KEEP (or 1): This option is similar to DELETE, except that only the elements N1 through T1 are kept, all others are deleted. All conductances or view factors with N1 through T1 as one of their elements, are kept. N1 = T1 = 0 defaults to all elements.
  • ALBDEL (or -13) deletes all albedo heat loads from VUFF.
  • BVFDEL (or -10) deletes all view factors from VUFF.
  • CAPDEL (or -5) deletes capacitances from MODLF and INPF for elements N1 through T1. N1 = T1 = 0 defaults to all elements.
  • CAPMDEL (or -19) deletes capacitances from MODLF only (not INPF) for elements N1 through T1. N1 = T1 = 0 defaults to all elements.
  • CONDDEL (or -6) deletes all conductive conductances from MODLF.
  • CONDEL (or -2) deletes conductive conductances, thermal couplings, and hydraulic flow resistances from MODLF and INPF for elements N1 through T1. N1 = T1 = 0 defaults to all elements.
  • EVFDEL (or -14) deletes all Earth view factors from VUFF.
  • HTFALBDEL (or -15) deletes all albedo heat loads from MODLF.
  • HTFIRDEL (or -16) deletes all Earth IR radiative heat loads from MODLF.
  • HTFSOLDEL (or -12) deletes all solar heat loads from MODLF.
  • HVFDEL (or -20) deletes all heat flux view factors in all spectra from VUFF.
  • NEARCDEL (or -8) deletes all thermal couplings from MODLF created with the Card 6e NEARCx options.
  • NEARXDEL (or -7) deletes all thermal couplings and conductances including (radiative conductances) from MODLF created with the Card 6e NEARx, CONV, RAD, COND, CSERIES, RSERIES, and FREE options, but not those created with the NEARCx options.
  • QDEL (or -4) deletes all radiative heat loads from MODLF.
  • RADDEL (or -3) deletes radiative conductances from MODLF for elements N1 to T1, except those created by Card 6e radiative thermal couplings. N1 = T1 = 0 defaults to all elements.
  • SVFDEL (or -11) deletes all solar view factors from VUFF.
