Full Equations (FEQ) Model for the Solution of the Full, Dynamic Equations of Motion for One-Dimensional Unsteady Flow in Open Channels and Through Control Structures
Purpose: The relation between the branches and the branch-end nodes is supplied with this block so that the information in the Network-Matrix Control Block (section 13.6) will properly define a system of equations describing the flow in the stream system. This block is required only if ISTYLE=OLD is in the Run Control Block (section 13.1). It is retained for support of the stream systems modeled using FEQ versions prior to 7.0. If ISTYLE=NEW, this block should not appear in the input.
Heading:One line of user-selected information. The suggested string is BRANCH-EXTERIOR NODE.
LINE 1Variable: HEAD
Format: A80
Example: BRAN UEXN DEXN
Explanation: This is a user-supplied heading for the subsequent lines of information.
LINE 2 (one for each branch)Variables: BNUM, UEXN, DEXN
Format: 3I5
Explanation:
BNUM is the branch number.The branches should be given in ascending order to make input easier to follow, but they need not be in ascending order.UEXN is the upstream branch-end node number.
DEXN is the downstream branch-end node number.
