Card 9 - TABDATA Analyzer Table Data

KODE

KODE is the code TABDATA (or 9)

N1

N1 is the table number.

T1

T1 is the value of the dependent variable.

T2

T2 is the value of the independent variable.

T3

T3 (optional) is the table number of the TABDATA Cards associated with the TABTYPE Card. If T3 is blank, the table number of the TABDATA Cards associated with the TABTYPE Cards is N1.

Code example

INTERP 3 2 6 1      
TABTYPE 6 QNODE TEMP 
TABDATA 6 22.6 100   
TABDATA 6 16.7 1000 
$ TABLE 6 CONTAINS TEMPERATURE DEPENDENT HEAT LOADS
$ FOR ELEMENT 3. THE HEAT LOAD VARIES FROM 22.7
$ TO 16.7 OVER THE TEMPERATURE RANGE 100 TO 1000

Notes

This card defines the data points of table N1 for linear interpolation by the Analyzer. Their order in the data deck must be such that the independent variable T2 is monotonically increasing. Tables with a single data point return a constant value.

If the independent variable is time, then the table is interpreted to be periodic, with a period equal to the (largest-smallest) time value in the table.

Tables may be referenced from INTERP Cards, Card 10 user-written subroutines, Card 6e AREA, MAT Material Property Cards, and PROP Physical Property cards.

The nature of the data contained in a table is specified on its TABTYPE Card.

It is a good policy to extend tables beyond their expected range, to ensure that during iteration the Analyzer does not exceed the table. If a table is exceeded, its last value is used and an error message is written to [Simulation name]_verbose.log.

For the special case when the independent variable code on the corresponding TABTYPE Card is OPERAT, and the dependent variable code is TABLE, the TABDATA Card may outline a sequence of operations involving interpolation, addition, subtraction, multiplication, division, and thermostat. For this option, the dependent variable must be a table number on the TABDATA Card, and the independent variable may be the code INTERP, ADD, SUBTRACT, MULTIPLY, DIVIDE, and THERMST. For a description of this, see the Notes section in Card 9 - TABTYPE Table Variable Type Definition.
