cYLHn-’E the axial length <strong>of</strong> a cylindrical structure. The old <strong>for</strong>m CYLHT = “cylht”<br />

= cylhite may also be used. (m)<br />

CYLELEV the absolute elevation <strong>of</strong> the center <strong>of</strong> volume <strong>of</strong> a cylindrical structure <strong>of</strong><br />

= cylelv type WALL, to be used in calculating the submergence <strong>of</strong> the structure in a<br />

cell with a pool. It should be noted that cylindrical structures only <strong>of</strong> type<br />

WALL may be submerged. By default the structure is assumed to be in<br />

contact with the gas space only. (m)<br />

CYLTHETA the azimuthal angle subtended by a partial cylindrical structure, in degrees.<br />

= Cyltht This input is provided to facilitate the modeling <strong>of</strong> submergible cylinders,<br />

since the common practice <strong>of</strong> taking penetrations into account by reducing<br />

the effective cylinder height introduces distortions in the calculated<br />

submergence. Default = 180°, corresponding to a half-cylinder. (degrees)<br />

VUFAC<br />

= vufac<br />

TUNIF<br />

= tunif<br />

TNODE<br />

tnode<br />

the view factor between structure and the lower cell as defined in Equation<br />

(10-36).<br />

the initial uni<strong>for</strong>m temperature <strong>of</strong> the structure. (K)<br />

a keyword to begin the specification <strong>of</strong> the initial temperature <strong>for</strong> each <strong>of</strong> the<br />

nodes <strong>of</strong> the structure. Use either TUNIF or TNODE, but not both.<br />

the value <strong>of</strong> the initial temperature <strong>of</strong> a node. Speci~ “nslab” values, going<br />

from the inner to the outer node. (K)<br />

COMPOUND the keyword to begin the specification <strong>of</strong> the material constituting each node.<br />

Each material must be among the materials specified after either the<br />

COMPOUND keyword or the USERDEF keyword in the MATERIAL block.<br />

cname the name <strong>of</strong> the material in a node. Specify “nslab” names, going from the<br />

inner to the outer node.<br />

x the keyword to begin the specification <strong>of</strong> the position <strong>of</strong> each <strong>of</strong> the node<br />

interfaces.<br />

(Xvals) the “nslab”+l positions <strong>of</strong> the node interfaces, starting with the position <strong>of</strong><br />

the inner surface. For cylindrical or hemispherical structures the positions are<br />

given in terms <strong>of</strong> the radius, which must be positive definite, except possibly<br />

<strong>for</strong> the outer surface, which can have a zero radius. The values maybe given<br />

in either ascending or descending order, depending on which surface is<br />

considered to be the inner or, more precisely, inward surface.<br />
