7.1.3.1. Filling the Element Table for Variables Identified By Name
To identify an element table column, you assign a label to it using the Lab field (GUI) or the Lab argu-
ment on the ETABLE command. This label will be used as the identifier for all subsequent POST1
commands involving this variable. The data to go into the columns is identified by an Item name and
a Comp (component) name, the other two arguments on the ETABLE command. For example, for the
SX stresses mentioned above, SX could be the Lab, S would be the Item, and X would be the Comp
argument.
Some items, such as the element volumes, do not require Comp; in such cases,Item is VOLU and Comp
is left blank. Identifying data items by an Item, and Comp if necessary, is called the "Component Name"
method of filling the element table. The data which are accessible with the component name method
are data generally calculated for most element types or groups of element types.
The ETABLE command documentation lists, in general, all the Item and Comp combinations. See the
"Element Output Definitions" table in each element description in the Element Reference to see which
combinations are valid.
Table 188.1: BEAM188 Element Output Definitions is an example of such a table for BEAM188. You can
use any name in the Name column of the table that contains a colon (:) to fill the element table via
the Component Name method. The portion of the name before the colon should be input for the Item
argument of the ETABLE command. The portion (if any) after the colon should be input for the Comp
argument. The O and R columns indicat e the availability of the items in the file Jobname.OUT (O) or
in the results file (R): a Y indicat es that the item is always available, a number refers to a table footnote
which describes when the item is conditionally available, and a - indicat es that the item is not available.
7.1.3.2. Filling the Element Table for Variables Identified By Sequence Number
You can load data that is not averaged, or that is not naturally single-valued for each element, into the
element table. This type of data includes integration point data,all derived data for structural line ele-
ments (such as spars, beams, and pipes) and contact elements,all derived data for thermal line elements,
layer data for layered elements, etc. These data are listed in the "Item and Sequence Numbers for the
ETABLE and ESOL Commands" table with each element type description in the Command Reference.
Table 188.2: BEAM188 Item and Sequence Numbers is an example of such a table for BEAM188.
The data in the tables is broken down into item groups, such as LS, LEPEL, SMISC, etc. Each item within
the item group has an identifying "sequence" number listed. You load these data into the element table
by giving the item group as the Item argument on the ETABLE command, and the sequence number
as the Comp argument. This is referred to as the "Sequence Number" method of filling the element
table.
For some line elements, KEYOPT settings govern the amount of data calculated. This can change the
sequence number of a particular data item. Therefore, in these cases a table for each KEYOPT setting
is provided.
7.1.3.3. Considerations for Defining Element Tables
- The ETABLE command works only on the selected elements. That is, only data for the elements you have
selected are moved to the element table. By changing the selected elements between ETABLE commands,
you can selectively fill rows of the element table. - The same Sequence Number combination may mean different data for different element types. For example,
the combination SMISC,1 means P1 for SOLID185 (pressure on face 1), and MECHPOWER for TRANS126
