## Definitions

Field Contents SI Unit Example
SID Set identification number.

(Integer > 0)

GSID Grid point set identification number.

Default = all grids in the model (blank or Integer > 0)

VT Initial velocity along the axis.

(Real)

VR Initial velocity about the axis.

(Real)

GA, XA, YA, ZA Axis origin. These fields define the origin of the axis. The point may be defined by entering a grid ID in the GA field or by entering X, Y, and Z coordinates in the XA, YA, and ZA fields; these coordinates will be in the basic coordinate system.

Default is the origin of the basic system (Real in all three fields or Integer in first field)

GB/XB, YB, ZB Direction of vector for axis definition. These fields define a point. The vector goes from the anchor point to this point. The point may be defined by entering a grid ID in the GB field or by entering X, Y, and Z coordinates in the XB, YB, and ZB fields; these coordinates will be in the basic coordinate system.

No default (Real in all three fields or Integer in first field)
