Local Systems for DOF's, Constraints and Reference

  This data set is used to define local systems used for constraints and DOF's at nodes. It may also be used to define reference systems into which results are to be transformed. A Local System Data Set is denoted by a `KEY' of 43 in the data set header record. For each local system there is a header record of the form:

KEY, SYSID, SYSTYP

To be written with the format:

FORMAT(1X, I2, 2I5)

Where:

KEY = -1 for a data header record -3 for a data set delimiter record which is an otherwise blank record inserted at the end of the data set.

SYSID = system identifier.

SYSTYP = system type (not yet used) 0 = cartesian system

Followed by data continuation records of the form:

KEY, XDCOSX, XDCOSY, XDCOSZ, YDCOSX, YDCOSY, YDCOSZ
KEY, ZDCOSX, ZDCOSY, ZDCOSZ

To be written with the format:

FORMAT(1X, I2, 6E12.5)

Where:

KEY = -2 for a data continuation record.

XDCOSX, XDCOSY, XDCOSZ = X, Y and Z components of Local X axis.

YDCOSX, YDCOSY, YDCOSZ = X, Y and Z components of Local Y axis.

ZDCOSX, ZDCOSY, ZDCOSZ = X, Y and Z components of Local Z axis.

Notes:

1.

Local Systems should be input in ascending SYSID order.

2.

The components (direction cosines) of the local axes are given with respect to the model global system.
