Tested stiffness calculations for rectangular bar and I-beams, and corrected some errors insodoing.
Fixed an error in the inertia evaluation code and reported some more properties related to the individual component densities.
Added sectional property evaluation code, untested. Should test with a few simple cases tomorrow. I-beams and simple composite sandwich sections.
After a client expressed interest, took inventory of old XSD (Cross-Section Development) MATLAB code, and updated the computation of the local inertias using the shoelace formula. Migrated the code to the Marian Scientific repositories.
