+#------------------------------------------------------------------------------------
+"""Box beam analysis with SONATA.
+
+Problem Description:
+====================
+
+This script performs a structural analysis of a composite box beam using SONATA.
+The analysis is based on the Smith-Chopra 1991 reference case and follows the
+Popescu/Hodges 2000 paper specifications.
+
+Problem Setup:
+==============
+- Rectangular box beam geometry with dimensions 24.2062 mm × 13.6398 mm (width × height)
+- Beam length: 762 mm
+- Composite layup: 6-ply antisymmetric laminate [30°/0°/30°/0°/30°/0°]
+- Each ply thickness: 0.127 mm
+- Material: AS4/3501-6 graphite/epoxy composite
+- Analysis stations: root (r/R=0.0) and tip (r/R=1.0)
+
+Analysis Objectives:
+=====================
+- Generate finite element mesh for the composite cross-section
+- Compute sectional properties using ANBAX (Asymptotic Numerical Beam Analysis eXtended)
+- Evaluate structural response and material distribution
+- Validate against reference solutions from literature
+
+Reference:
+=============
+- Smith, E.C., Chopra, I. (1991). "Formulation and evaluation of an analytical model for
+composite box beams." Journal of the American Helicopter Society, 36(3), 23-35.
+- Popescu, B., Hodges, D.H. (2000). "On asymptotically correct Timoshenko-like anisotropic
+beam theory." International Journal of Solids and Structures, 37(3), 535-558.
