Internal Boundary Surfaces Card Syntax (CO2E)

Internal boundary surfaces can be specified directly via this card or by using an external file. If a split, or discontinuity in the interior of the grid occurs, then internal boundary surfaces are implicitly defined and do not need to be explicitly defined in the Internal Boundary Surfaces Card.

Input Data Types

Info

For the Cartesian coordinate system, the terms west, south, and bottom refer to the negative x-, y-, and z-directions, respectively, and the terms east, north, and top refer to the positive x-, y-, and z-directions, respectively. For the cylindrical coordinate system, the terms west, south, and bottom refer to the negative r-, θ-, and z-directions, respectively, and the terms east, north, and top refer to the positive r-, θ-, and z-directions, respectively.
