very pretty, for an instaneous model can you make the graph cylinder shaped?

Hi Sleepy
yes can do so but on JrB duty at present. Could also do an animation i.e. A cylinder which uptates at 100x real time for example...

That's pretty - what are you using for the graph generation?

We're going to be in need of a Navitron software bucket soon with lots of people producing useful bits of code and config.

Wookey
sorry coded in MATLAB - can port to GNU Octave Forge and possibly C or Java. Just thinking about the best tank visualisation methods. This is of course just a bit of flash front end - the big job is the tank model. At present I have 100 slices in the tank and based on State Space theory
http://en.wikipedia.org/wiki/State_space_%28controls%29
but that may not be up to the task. The mass flow terms are a major challenge also how far unmeasured states to the tank can be inferred from measured outputs. This might work (or not?)
http://en.wikipedia.org/wiki/Observability
 And of course there is
http://en.wikipedia.org/wiki/Kalman_filter
Can we tell our pump is in without a sensor - infer water rates etc?

Wouldn't attempt any of this without MATLAB/ Octave forge  - unless anyone else is going to suggest something better? These are proper algorithms - dare I say real computing - not this database flimflam!
