Element Definition (Topology) Data Records

 

An Element Topology Data Set is denoted by a `KEY' of 3 in the data set header record. For each element there is a header record of the form:

KEY, NUMBER, TYPE, GROUP, MATERIAL, VARIANT, PHYSICAL

to be read with the format:

FORMAT (1X, I2, 4I5, 5X, 2I5)

or: FORMAT (1X, I2, I10, 3I5, 5X, 2I5) for 10 digit element number format

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.

NUMBER = element number

TYPE = element type (see Appendix C)

GROUP = element group number

MATERIAL = material property number

VARIANT = element variant number

PHYSICAL = physical property number

Followed by data continuation records (for definition of the element topology) of the form:

KEY, NODE1, NODE2, ..., NODE15

To be read with the format:

FORMAT (1X, I2, 15I5)

or: FORMAT (1X, I2, 15I10) for 10 digit node number format

Where:

KEY = -2 for a data continuation record

NODE1 etc. = node numbers defining the element

Notes:

1.

The data continuation record (KEY = -2) will be repeated as necessary for elements having more than 15 nodes.
