Figure 16.3: Shell Tool With Section Controls Page Displayed
The transverse shear stiffness, hourglass coefficients and drill stiffness of the sections are calculated
from the section geometry and material properties. The default added mass per unit area of the section
is always zero. On the Section Controls page, you can override the program calculated quantities
[SECCONTROL]. ( The Section Controls page does not apply to thermal shell elements.)

16.2.8. Managing Cross-Section Libraries
Cross-section data for shell sections can be stored in cross-section libraries. To create standard cross
sections for later use, create one or more cross sections, edit the Jobname.LOG file, and copy the ap-
propriate SECCONTROL,SECDATA,SECFUNCTION,SECOFFSET, and SECTYPE commands into a sep-
arate file with a SECT extension.
16.3. Using Preintegrated General Shell Sections
You can use preintegrated general shell sections (SECTYPE,,GENS) when using the SHELL181 or SHELL281
element, provided that linear elastic material behavior is acceptable. Compared to standard shell usage
