Release version 5.4.1a, February 24th, 2017

(Build 20.2.2017 rev.14444, ATENA Studio, GUI 3D 20.2.2017, 2D 17.1.2017, SARA 5.8.2016, ATENA-GiD scripts rev. 14439), size 1 331 450 518B

We expect this version to be especially interesting for user who want to try the new features, above all injected cables and 2D shells + 1D beams (the new element types are only available through the ATENA-GiD interface of ATENA Science).

There are new examples included with the installation to illustrate the new features (typically installed into %Public%\Documents\ATENA Examples\Science\GiD):

injected cables


2D shells and 1D beams
