the Rationale behind DIVE

• DIVE is a little piece of software for simulation of dives,
• it is a tool for intermediate/advanced diving students (**);
• showing what's going on during compression / decompression
• that is: gas absorbtion during descent / diving, gas release during ascent.
• The Simulations (*) are done numerically, i.e. with long columns of digits,
• as well graphically, via a bar chart.
• So the student could check, whats going on internally in a Dive Computer,
• or why Deco Tables look like what they are looking
• The differences between AIR and NITROX / EAN mixes become lucid,
• also with any arbitrary mix gases like TRIMIX or HELIOX
• in short: it is a tool, exclusively for learning.
• One could check, what happens during:
• No-Stop or Decompression Dives
• how easily NDL-Tables, or complete Deco-Tables are produced,
• as well small run-times are no flying magic,
• the possibilities of lowrisc decompression;
• the impact of various deep stops or accelerated Decompression on the time-to-surface (TTS);
• how big (or how small) the influence of certain methods on the TTS is;
• the difference between the old Buehlmann- and the new Hahn-Model;
• the basic paradigm of "DIVE" is in the following chart:
  

• the basic parameters of a (Multi-Level) dive:
• like various times at different depths,
• the gasmix (Air, Nitrox, Heliox, ...)
• ascents and surface intervalls:
• are starting the Service Engine, which computes
• the compartment saturations, that is: how much inertgas is in group of specific tissues
• the output goes through an I/O Module
• the adaption of the already calculated compartment saturations is done in:
• the Tool Box, with various possibilities:
• like, for e.g.: asymmetric Desaturation, or with 100 % O₂, ...
• or, with topical methods from the United States Navy or from the DSL Labor (DAN / UWATEC).
• Details in the chapter: "FEATURES" resp. in the german documentation: the handbook for download.

• (*) Attention:
• Simulation means in this context, bluntly speaking: there are a couple of very basic asumptions!
• Simulation does not mean, that this will happen exactly in your body during a dive!
• (**) Advanced + Nitrox certifications are helpful
