This dialog allows you to define pattern curves for the Air Flow Curve Engineering Library.

The following buttons are located above the curve points table on the left.

• New: Creates a new row in the curve points table.
• Delete: Deletes the currently highlighted row from the curve points table.

The curve points table contains the following columns:

• Time from Start: Lets you specify the amount of time from the Start Time of the pattern to the time step point being defined.
• Relative Closure: The initial relative closure used at the start of a steady state or EPS run. (A relative closure of 0% means the valve is 0% closed, or 100% open. Conversely, a relative closure of 100% means the valve is 100% closed or 0 % open).
