Establishes the size or the number of divisions for the tessella pattern of the bridge cross sections
PREP7 : BRIDGE AND CIVIL NON LINEARITIES: Model generation
ISEC
Number of the bridge cross section (for Lab2=SIZE)
Lab1, Lab2, Lab3
Property to define or to modify the bridge cross section. The valid labels and the used fields are shown hereafter.
VALUE
Value to assign to the specified property in Lab1, Lab2 and Lab3.
IDX1, IDX2, IDX3
Identifying index of the property to modify. The valid values depend on the different properties defined in Lab1, Lab2 and Lab3 and are described hereafter.

Notes
- The number of divisions in each part of the cross section must coincide for each section of the bridge. Therefore the division’s number will be common for all the defined cross sections.
- When the shell model type will be generated, only box cross sections are allowed and the number of divisions in the flanges and web widths are ignored.
- When a tessella maximum size is chosen, the section number to be applied must be specified.
- When Lab2=SIZE or Lab2=HCELL are applied on a slab section, the values for Lab2=RCELLBOT and Lab2=LCELLBOT will be replaced.
