    1. INTRODUCTION

    This document contains release notes for ATENA version 5.9.0
    All bugs and problems should be reported by e-mail to
    cervenka@cervenka.cz.

    2. INSTALLATION

    First make sure that your ATENA hardlock is connected
    to your computer. It is recommended to uninstall any previous
    versions of ATENA software from your computer. In some cases
    it may be necessary to manually remove the directory
    "c:\Program Files\CervenkaConsulting".

    Execute the program ATENA_V5xx_SARA_Install.exe, which is located on your 
    distribution medium. This can be either a CD or a compressed archive, if 
    you downloaded the program from the Internet. The installation
    program will guide you through the installation process. The intallation
    sometimes needs to upgrade some of your system files. In this case
    you will be asked to restart your computer.
    
    For a silent intallation, i.e., no questions, default settings, you can 
    run the installer with the /S switch. 
    
    The installer language follows system language and preselects czech 
    Engineering UI in case of czech Windows environment. To choose the installer 
    language manually, you can use the command line switches /EN for english 
    and /CS for czech.     

    2.1 ATENA Engineering 2D 

    During the installation process you will be asked to select 
    the required components. ATENA 2D is one of the available
    components. This program allows you to perform non-linear
    finite element simulation of concrete or reinforced concrete
    structures using two-dimensional finite element models.
    This program contains a graphical user interface for
    data-preparation, analysis control and monitoring and
    for the post-processing.

    2.2 ATENA Engineering 3D

    ATENA 3D is a similar graphical environment as ATENA 2D,
    but it provides the same functionality for full three-dimensional 
    analysis. This program allows you to perform non-linear
    finite element simulation of concrete or reinforced concrete
    structures using three-dimensional finite element models.
    This program contains a graphical user interface for
    data-preparation, analysis control and monitoring and
    for the post-processing.

    2.3 AtenaConsole, AtenaConsole64 

    AtenaConsole is additional component, which allows you
    to execute ATENA finite element calculations in a batch
    mode environment. It can be used for two-dimensional
    as well as 3D analyses.

    2.4 AtenaStudio, AtenaStudio64

    Advanced graphical user interface for ATENA.
    Combines simple and intuitive user interface known from ATENA Engineering
    and advanced features of AtenaWin. It can be used for 2D and 3D calculations
    as well as visualization and postprocessing results.
    
    2.5 AtenaWin, AtenaWin64 

    AtenaWin is additional component, which allows you
    to execute ATENA finite element calculations in a batch
    mode environment. It can be used for two-dimensional
    as well as 3D analyses. It differs from AtenaConsole
    by a simple graphical environment that allows users
    to visualize results and data from finite element
    calculations. It also contains mesh generation capabilities
    if a boundary representation of the model is provided.
    It is especially suitable for expert users that need
    to exploit the additional functionality of the FE
    solution core that is not supported by the ATENA 2D
    and 3D graphical environment.    

    2.6 ATENA Science ATENA-GiD Interface

    If this component is selected, interface modules for
    data exchange between ATENA and GiD will be installed
    on your computer. GiD can be used as a 3D and 2D pre- and post-processor 
    for ATENA. Currently, the postprocessing is limited in some respects in GiD. 
    The post-processing can also be done in AtenaWin or Atena3DPost.

    Only the demo version of GiD is currently distributed 
    with the ATENA software. The demo version is limited
    to 1000 elements. GiD can be used to prepare numerical
    models for very complex structures. It also supports
    imports from various modelling standards. The full licence
    of GiD can be obtained from ATENA distributors. More
    information about GiD can be obtained at the internet
    address:
    
    http://www.gidhome.com/

    During the installation you will be prompted if you
    want to install demo version of GiD and ATENA-GiD interface.
    If you want to use ATENA along with GiD please select 
    the appropriate boxes.

    In order to execute ATENA directly from GiD on older Windows 95 and 98 
    operating system it is necessary to define the following environmental variable

    set AtenaConsole="C:\Program Files\CervenkaConsulting\AtenaV5\AtenaConsole.exe"
    set AtenaWin="C:\Program Files\CervenkaConsulting\AtenaV5\AtenaWin.exe"
    set Atena3DPost="C:\Program Files\CervenkaConsulting\AtenaV5\Atena3D_1_EN.exe"

    where the path should be correctly to the directory, where the programs 
    are located. On Windows NT, 2000, XP, Vista, 7, 8, 10 this variable is created 
    automatically during the program installation.

    The distributed ATENA-GiD interface supports GiD version 7.7.2b and 
    later, for details, see GiD\Problemtypes\Atena\Readme.txt 

    2.7 Installation of NetHasp network hardlock.

    This section describes how to install the network hardlock for
    program ATENA.

    If you had requested a network version of ATENA, you received
    a red NetHasp hardlock. This hardlock can be plugged into 
    the parallel port of an arbitraty computer in your local area
    network (LAN). The program ATENA can then be installed on
    any computer connected to this network and running 
    Windows 10 system (32 or 64 bit). 
    The good practice is to place the content of the installation CD 
    on the server, so that everybody can install it on his or her computer.
    When ATENA is executed on a client computer, it first checks 
    if a valid Hasp hardlock is connected to the computer. 
    If it cannot find a hardlock on the local computer it searches 
    the network for a NetHasp hardlock. After the NetHasp is located,
    the program attempts to log into the NetHasp hardlock. If there
    are more workstations currently using ATENA then is the allowed
    limit, the login is refused and ATENA cannot be used.

    In order to use the network hardlock, the red NetHasp hardlock
    key must be connected to at least one computer in the LAN,
    and the NetHasp License Manager must be running on this computer.

    The NetHasp License Manager for Windows 10
    is located in the directory

    %ProgramFiles%\Common Files\Fine Shared\System\win32 
    
    and is called lmsetup.exe. It can be executed directly
    from there to install the license manager. Its latest version can be  
    downloaded from the HASP/SafeNet web at http://www.safenet-inc.com/ 

    It is important to realize that the computer with
    the network hardlock and NetHasp license manager must
    be running, in order for the client computers to be
    able to access it and log into the NetHasp.

    Some problems may occur, if for some reason an ATENA
    sesion on a client computer fails to end correctly,
    due to a computer or program crash. In this case, the program
    did not log out of the NetHasp License Manager, and
    one license can be blocked for others to use. There are
    two solutions to this problem. Either ATENA can be started
    again and the blocked license will be freed after the program
    is correctly terminated. Or NetHasp License Manager can
    be stopped and restared again. This will reset the number
    of available licenses back to the original number. This should
    be done, however, only at times when there are no clients using
    ATENA.

    It is important to note that if ATENA is executed several
    times on a single computer, this scenario will consume
    only one license in the NetHasp License Manager.

      This introduces an incompatibility with the previous program versions. 
      It is unfortunately not possible to display the results from older 
      versions of the program. Only input data from older version can 
      be loaded into Atena 2.0.1. Therefore, Atena 2.0.1 will install 
      into a new directory so that the previous version of ATENA is preserved
