TUNA
TUNA is a fully automated computer program developed for TUNnel Analysis. The program is written by the professional engineer with more than 30 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.
