Version 3.00 of Ftool was released on 02/Aug/2012 and has been updated to fix the following problems:
(1) Updated on 19/Aug/2012: The program stopped working in very rare situations of analysis of influence lines or envelops of vehicle live load effects.
(2) Updated on 22/Aug/2012: The program stopped working when a concentrated force load was applied at a node with an inclined support (with skew angle).
(3) Updated on 03/Sep/2012: The program stopped working when a prescribed displacement or rotation component was applied with a null value.
(4) Updated on 06/Sep/2012: The program was not considering temperatura variation effects in the results.
(5) Updated on 19/Sep/2012: The program was given wrong internal force results for a model with all degrees-of-freedom fixed and with at least one component of prescribed displacement or rotation.
(6) Updated on 23/Nov/2012: Fixed input of structural models created prior to version 2.12: moment of inertia of generic cross-section was set with a null value.
(7) Updated on 08/Dec/2012: In case of a double click on a file with extension ".ftl", the program ran but did open the file.
