Element and Node Set Definition Data Records

 

An Element Set Definition Data Set is denoted by a `KEY' of 19 in the data set header record. A Node Set Definition Data Set is denoted by a `KEY' of 18 in the data set header record. For each set of elements or nodes there is a header record of the form:

KEY, Setname, Text

to be written with the format:

FORMAT (1X, I2, 8A1, 2X, 30A1)

Where:

KEY = -1 for a data header record

= -3 for the data set delimiter record which is an otherwise blank record inserted at the end of the data set.

Setname = name of set (see the CONSTRUCT SET and UTILITY TABULATE SETS in the User Manual)

Text = descriptive text for set

Followed by data continuation records (for definition of the elements or nodes in the set) of the form:

KEY, ID1, ID2,..., ID15

To be written with the format:

FORMAT(1X, I2, 15I5)

or: FORMAT (1X, I2, 10I10) for 10 digit element/node number format

Where:

KEY = -2 for a data continuation record

ID1 etc. = element or node numbers defining the set

Notes:

1.

The data continuation record (KEY = -2) should be repeated as necessary for sets having more than 15 elements/nodes (or 10 elements/nodes with the 10 digit element/node number format). The final card may contain less than 15 elements/nodes (or 10 elements/nodes with the 10 digit element/node number format).

2.

An element/node may belong to more than one set.

3.

Nodes must be specified in ascending order.

4.

Elements must be specified in the same order as defined in the topology data.
