THIS VERSION IS A MAJOR UPDATE (from v1.14a or newer)
BEWARE:

• it is compulsory to install the update JRE 1.6 so that Talren 4 v2.x works properly. If you haven't installed this Java update yet, you may download it using the link in the left column.
• Talren 4 v2 can read Talren files generated with previous Talren 4 . But files saved with Talren 4 v2 CANNOT be read with previous versions anymore. So you should make a copy of your existing prj files before opening them with Talren 4 v2 if you want to be able to open them again with Talren 4 v1.

Improvements

• Optimisation of speed and memory handling: operations are globally much faster (switching through phases and situations, loading/saving, output display, printing, etc) and computer memory doesn't get saturated anymore.
• Talren 4 files structure has been modified. A directory is now created for each prj file: project-DIR. This directory includes all temporary files handled by Talren 4 for each project file. But the prj file is the only necessary file when you want to send your project to another Talren 4 user.
• Additional calculation method available: yield design method (with logarithmic spirals). Additional information about yield design method.
• Correction of the user interface to make it compatible with Korean systems.
• Correction of soils deactivation problems.
• "Undo" option during geometry drawing (available only for mouse operations),
• Correction of the automatic position for the external water level (on the right side of the slope).
• Correction of soil properties "switches" on the model when reloading an existing prj file.
• Correction of the handling of strips parameters in the calculation kernel (qs safety factor, internal/external mode).
• Possibility to activate/deactivate superposed elements (reinforcements or loads: popup menu item in stages mode).
• Possibility to print all phases and situations at once.
• Correction of zoom level after calculation.
• Automatic display of the general settings dialogue box when creating a new project.
• Display of a gauge not only during calculations but also during loading of the result files.
• Possibility to import pore pressure meshed as text files (nodes and triangles).
• Various minor points.

Improvements

• Correction of punctual slowing down for given files when handling the geometry (deactivation of soil clusters, removal of points, etc).
• Correction of the display of polygonal failure surfaces 2 to n : their diaply was correct after calculation but not before (except for situation 1). The display is now updated when the failure surface is defined/changed.
• Beware: it is compulsory to install the update JRE 1.5 so that Talren 4 v1.33 works properly. If you haven't installed this Java update yet, please refer to the comments about update v1.23 below.

Improvements

• Printing of the graphical page: correction of automatic margins for inkjet printers (type HP 2600 or 2800 for instance).
• Printing of the graphical page: if patterns are selected rather than colors, the legend is displayed with patterns too.
• Addition of a new control on linear loads: their inclination should be in the range [0, 180°]. The value for Q can be either positive or negative.
• Correction of a display option for strips (choice of the weighting factor).
• All files should be saved when first switching to stages mode.
• Beware: it is compulsory to install the update JRE 1.5 so that Talren 4 v1.31 works properly. If you haven't installed this Java update yet, please refer to the comments about update v1.23 below.

Improvements

• Compatibility with Java Runtime Environment 1.5: beware, it is necessary to install JRE update 1.5 so that Talren 4 v1.23 works properly. To install JRE update, download the installation file with the link on the side. Then execute the file jre1_5_0_04_i586_p2.exe and follow default instructions.
• Note: to check your JRE version, check the name of the latest jre or j2re sub-directory in C:/Program Files/Java (or in the JRE installation directory in case it is different).
• If the latest sub-directory name includes a number like 1.4.xxxx, then you need to install the JRE update.
• If the latest sub-directory nape includes a number like 1.5.xxxx, then you don't need the JRE update.
• Correction of the calculation when taking into account struts inclined with an angle out of the interval [-90°;90°].
• Printing of the forces in the reinforcements in the case of polygonal failure surfaces.
• .tra files (temporary result files) are automatically deleted when closing a prj file (they are very space-consuming and it's not useful to save them).
• Warnings provided during calculation by the calculation kernel are now explicit (in the precious versions, they were only including an error number).
• Water unit weight: it is automatically and immediately converted when the unit system is changed (in the previous versions, it was automatically converted but only when validating the project dialog box).
