TUNA (TUNnel Analysis)

back1.jpg (4230 bytes)

TUNA is a fully automated computer program developed for TUNnel Analysis. The program is written by the professional engineer with more than 20 years of experience in tunnel analysis.

TUNA employs a static, two-dimensional, linear elastic finite element method. Pre- and post-processors are built-in so that only the physical geometries and material properties associated with a proposed tunnel are required as input and graphical otput can be obtained directly through dot matrix/laser printers or high resolution plotters.
