Installation

Start the installer „setupFluxion.exe“ imin your download folderto installe the program on your current user account.
Confirm the end user agreement and follow the instructions.
Start "Fluxion.exe" by double-clicking.

NOTE: An installer for all users of your computer can be found here (Admin rights required).

If not done automatically by the browser, open the "Fluxion.dmg" file in your download folder.
After confirming the end-user agreement, drag the "Fluxion" program into the program folder or anywhere on your hard drive.
Start "Fluxion" by double-clicking.

Unzip the file "Fluxion_Jar.zip" in your download folder.
Move the extracted folder to the desired location in your user folder.
Depending on the configuration of the installed Java, either start with a double click, via the context menu or via the terminal. To do this, switch to the Fluxion folder in the command line and start the program with "java -jar Fluxion.jar".

New features and improvements:

NEW: It is now possible to enter own (one-step) iteration methods (e.g. s_next=s_prev+v*dt)
NEW: Model equations can now be formulated using vector syntax (e.g. r' = [v₁|v₂|v₃] ...))
NEW: It is now possible to define own functions directly in the modeling field (before use!)
IMP: Import for comparison values improved (incl. settings dialog for text files .txt & .csv) more file formats added: .csv, .labx, .labm, .mmd, .gambl
IMP: The update notification was improved
IMP: Optimizations have increased the computing speed (up to a factor of 2)

IMP: during model input, entries are now made for support in the start value field
FIX: Display errors fixed where selections were not plotted correctly
FIX: The opening of documents of older program versions improved
FIX: The activated table type is now taken into account during saving/loading
FIX: Various minor bugs of the user interface have been fixed
FIX: Fixed the bug that the program did not always recalculate when the slider was moved
FIX: Misleading message in case of no longer defined sizes in a self-defined table corrected
FIX: Fixed a bug when using self-defined functions in further equations
FIX: Fixed localization error with embedded JVMs (WIN/MAC)
FIX: Loading of erroneous projects is no longer interrupted by mistake
