RMODIF, NSET, STLOC, V1, V2, V3, V4, V5, V6
Modifies real constant sets.
NSETNumber of existing real constant set to be modified.
The label GCN is also valid input for general contact interactions (see Notes).
STLOCStarting location in table for modifying data.  For
example, if STLOC = 1, data input in the V1 field is the first constant in the set.  If STLOC = 7, data input in the V1 field is the seventh constant in the set, etc.  Must be greater
than zero.
V1New value assigned to constant in location STLOC.  If zero (or blank), a zero value will be assigned.
V2, V3, V4, . . . , V6New values assigned to constants in the next five locations. If blank, the value remains unchanged.
Allows modifying (or adding) real constants to an existing set [R] at any location.
Specify NSET = GCN to define/modify real constants for real constant sets that
were previously assigned by the GCDEF command (that
is, real constants used in general contact interactions).
This command is also valid in SOLUTION. For important information about using this command within the solution phase, see What Are Nonstandard Uses? in the Advanced Analysis Guide.
