VECTOR
ovname
keyword that initiates input of the name for the specific vector type
comprising a given curve. Curves are only written to the vector file if a name
is specified through use of this keyword. The VECTOR keyword applies
only to individual curves and not the entire TDB. If no vectors are defined,
the vector file will not be created or will be created with a zero file size.
the name of the curve that will be written to the vector file. This name can
be any string up to eight characters in length and not containing an input
delimiter.
IK.EY1 and item keywords as defined in Table 16-1. It is important that item keywords
IKEY2 are understood since they compose the major portion of TDB curve
definitions. These keywords are discussed separately because a different set
of keywords applies to each individual plot flag. Item keywords are used to
identi~ which element of a data record of a particular flag is to be extracted
for the TDB curve being defined. Normally, an item keyword must be
followed by either one or two values. These values maybe numerical values
or character strings. Two item keywords are listed here, IKEY1 and IKEY2,
because in some instances an item keyword maybe followed by another item
keyword, which in turn must be followed by one or two values. Further
clarification of item keywords and a few examples are given below.
valuel; value2 identi~ing values for an item keyword. The validity of the value given is
determined by POSTCON based on various entries for control information
written to the plot fde by CONTAIN. Most values are either character strings
(eight character maximum) or integers. As mentioned above, some item
keywords are followed by an additional item keyword, which in turn must be
followed by an appropriate value field. The “va.lue2” field is required in a
few cases where the item keyword requires two entries as opposed to one. A
short discussion of the contents of a typical CONTAIN plot file record is
given below for further clarification of item keywords and values.
When CONTAIN writes information onto a plot file, it labels each record
with a flag (and usually a cell number). However, each individual numerical
value written to the plot fde obviously cannot have its own unique flag.
Instead, results are grouped into categories and then written with the same
flag. For example, structure temperatures for all structures and all structure
nodes are written with a 610 flag. In this case, item keywords followed by
the appropriate values would be used to identify which structure and which
node temperature to extract. Perhaps some actual examples of IKEY1 and
IKEY2 input blocks will clarify the above discussion. In the examples
below, the item keywords are boldfaced in order to distinguish them from
constant values, since both are capitalized according to standard CONTAIN
notational conventions.
