History

    Implemented applications in OPL (programming language used on Psion) and Pascal for nonlinear dynamical simulations (1999).
    Diploma thesis focused on dynamical simulation of nonlinear SDOF model of cantilever beam (2000), see in czech language 2000.06.diplom.html.
    C++ application Dynakce, which uses mass spheres, connected by Translational springs and Rotational springs (2001), see in czech language 2002.05.im.html.
    Implemented discretization method for static solving of spring model (applications Statvzp and Statvmis, 2003), see 2004.06.delft.html.
    C++ application FDK compiled by DJGPP for modelling of 3D problems (2005).
    C++ application FDK2D (2006).
2D v0.00 The first Java version (2007.08.06).

2D v1.03 First free Java version (2007.12.30).
2D v3.00 Format of the data files was modified into XML (the application is backward compatible).
2D v3.02 Fixed bug in Spring Function.
2D v3.03 Added possibility to create the force as follower.
2D v3.04 Improved selecting.
2D v3.07 Fixed bug in the force class (since v3.03).

2D v3.14 Added two color function classes.
2D v3.16 Changed the name of a color function.
2D v3.18 Fixed bug in the spring function. The pseudoatom interaction was implemented.
2D v3.20 Implemented the polygonal spring function. The color functions were changed according to the open source Java package cz.kitnarf.colorfunction.
2D v3.25 Implemented 'new' and 'change' dialogs for the polygonal spring function.
2D v3.26 Implemented export of the actual state to the TXT file.
2D v3.28 Implemented three types of time function for the size of a load (cannot be accessed from the gui). Czech version of the language dictionary is now available.
2D v3.29 Command 'Save state as TXT' was expanded for the Springs.
2D v3.36 New command 'Save as SFDK' enables saving of a model as Simple FDK file useful for nVidia CUDA FyDiK2D parallel implementation. Added indexation of model objects in the XML data files.
2D v3.37 Last version which uses nonindexed references. Last backward compatible version. Use it to convert FDK data files into indexed (version 4).
2D v4.02 First version using indexed references only. Older FDK data files can be converted for this version by the version 3.37.
2D v4.03 Added Short Guide.
2D v4.05 Improved for fast opening of large models.
2D v4.07 Changed behaviour of Mass Points which have restrained all state variables. Implemented time functions for coordinates of a coordinate-restrained Mass Point.

2D v4.33 Fixed bug in automatic start and break of solving. Added console switch suppressGUI.
2D v4.34 Fixed bug in Mass Object indexing. Added possibility to delete a Spring Function and invert selection in the Spring function organizer. Added possibility to invert a Color function.
2D v4.42 beta Many improvements. Damping can be specified for each spring object (it is not yet implemented for Quadrilateral element) and does not need to be mass proportional. Mass can be now distributed by all objects which can carry mass. Fixed application exit procedure (method dispose). Added possibility to show stress in Translational spring and Rotational spring. Improved calculation of angle of Translational spring (please check influence of this change).
2D v4.43 beta Added possibility to show maximal tau (shear stress) in the Quadrilateral finite element.
3D v1.04 First free Java version of FyDiK3D (2010.10.17).
2D v4.47 beta Added reporting of exception throwed during loading of data files.
3D v1.06 Improved selecting of objects by box. Language dictionary relocated inside the JAR package.
2D v4.49 Improved selecting of objects by box. Language dictionary relocated inside the JAR package.
3D v1.08 Added 3D transformation and associated buttons in the View Panel.
2D v4.50 Changed indicator of the coordinate system according to the 3D version.
2D v4.52 Changed SFDK export. Fixed bug in the saving of state file of Quadrilateral finite element, thanks to colleague Tom� Pail.
2D v4.55 Method save was synchronized. Added possibility to specify Polygonal spring function as inelastic.
