The number of sub-blocks in the computational domain where time histories are to be output is designated in the "general input" section (BOUNDARY AND CUT CONTROL) by the parameter TIME HISTORY I/O (>= 0). The first line of input for this section is a comment line for comments about the input to follow (the $ delineator is not required). The sub-block is created as a subset of a grid block defined by a bounding box in computational space. This subset (or sub-block) is defined by the beginning and ending grid point indices specified in the I, J, and K directions.

Example: Comment line and time history sub-block definition

Where:

TIM S.B.: CHARACTER STRING; Sub-block name. Up to 10 characters used to indicate where the sub-block is located. Not used by code; provided as a user convenience.

BLK:INTEGER; Block number of the sub-block in which the time history is desired.

DIR1:CHARACTER STRING; Direction "1" for defining the sub-block window.
I = I constant boundary
J = J constant boundary
K = K constant boundary

BEG:CHARACTER STRING; Grid point at which to begin sub-block which runs in the direction specified by DIR1.
MIN = Start at minimum index of DIR1
MAX = Start at maximum index of DIR1
25  = Start at index 25 of DIR1

END: CHARACTER STRING; Grid point at which to end sub-block which runs in the direction specified by DIR1.
MIN = End at minimum index of DIR1
MAX = End at maximum index of DIR1
65  = End at index 65 of DIR1

NOTE 1: BEG must be less than or equal to END.

NOTE 2: The sequence (DIR1, BEG, END) is repeated twice, for DIR2 and DIR3.

The variables that are output are specified in the OUTPUT CONTROL DATA section of the input deck.
