Ecolego Workshop 2011 (April 12 2011)

The date for this years Ecolego Workshop has been set to the 10th-14th of October.

For those of you who have attended this course before, the setup is as usual:

We start off with a two day crash course in Ecolego basics. After that follows a two day presentation of new exciting features both in Ecolego 5 and in the upcoming new release: Ecolego 6. On Friday we finish the week of with a seminar where the participants are welcome to present their current work in Ecolego and discuss solutions to problems.

Ecolego on Wikipedia (March 9 2011)

Ecolego is now available on Wikipedia! Check it out:

Update of Ecolego (January 7 2011)

New features:

• The sensitivity analysis toolbox has been completely re-written and has a new user interface and several new options.

• The report settings window has been updated, and the report has been much improved. There are now three report-templates available to quickly change the report settings.

• All buttons now have correct short-cuts and mnemonics.

Update of Ecolego (November 23 2010)

New features:

• Model inputs and model outputs can be limited to only accept connections to one other output/input.

• The auto-connect feature can be turned off for a specific Model inputs / model output.

• Objects can be “locked” by setting the “Editable” flag. This is useful if you wish to distribute a model via Ecolego player and do not want the user to change specific values.

• Objects can be “hidden” by unchecking the “Visible” flag. This feature only applies to when the model is displayed in Ecolego player.

• As a move towards the much requested feature Undo/Redo: Ecolego can now help you track changes to a model. This feature is not fully complete yet, but is still useful enough to be included in this release. To enable change tracking, open the new history window? and click the toolbar button. Or, from the Edit menu; select “track changes”. After “track changes” has been activated, changes to parameter values will be highlighted in the parameter tables and in the report.

• The statistics table has been blessed with many more statistics options.

• Many bugfixes

Downloads from the Ecolego Workshop (October 15 2010)

Update of Ecolego (September 17 2010)

New features:

• General variables can now be assigned different values depending on index. This makes it possible to create models where the user can select which calculation should be performed for a specific substance. For instance, consider a model with a general variable for a distribution coefficient. The user can now select which way the distribution coefficient is calculated depending on substance.

• The report has now been repolished and several bugs related to the report has been fixed. It is now also possible to save templates for the report from the report settings window.

• Many small bug-fixes

Ecolego Annual Workshop (July 23 2010)

As the vote was unanimous, the dates for the annual Ecolego workshop has been set to 11th to 15th of October.The workshop will be held close to Facilia’s main office in Stockholm, Sweden.

Preliminary agenda

Monday/Tuesday - Beginners course in Ecolego.

• Learn to use the basic functionality of Ecolego.

Wednesday/Thursday - Advanced Ecolego.

• All new features of Ecolego 5 will be explained.

Friday - Ecolego applications

• We wish to invite our customers to present their work with Ecolego

If you are interested in joining the workshop, please register by sending us an e-mail letting us know which days you wish to attend and if you wish to make a presentation of your work on the final day.

Eikos Java beta version available (June 23 2010)

We have for some time been working on a stand-alone version of Eikos that does not require Matlab.

An early beta version is now available for download in the downloads section. Eikos Java will be free of charge while being beta tested.

5.0.78 Update of Ecolego (June 23 2010)

This update fixes minor bugs related to the library and copy/paste.

5.0.66 Update of Ecolego (May 25 2010)

New features:

• Web proxy host and port can be specified for when retrieving updates. In most companies all web traffic is directed via a proxy, and this has prevented people from receiving automatic updates. To edit the proxy host and port, go to File|Preferences and open the Startup page.
• Off-line help bundled with Ecolego, so that the help documents can be browsed without connection to the internet
• Search field for help in the main toolbar
• New block: discrete event. This block should be used in combination with conditions, so that the solver discovers important time points in the simulation.
• The recorder block has been updated to take two arguments rather than one for reset/record.
• The recorder block has been updated to support calculating the mean value of a given output.
• The matrix window now displays icons for adding empty cells in its title bar.
• The results window displays icons for the outputs that matches the icons in the project tree. This makes it easier to see which type of object is behind the output.
• The information window now displays graphs for lookup tables.

5.0.45 Update of Ecolego (April 23 2010)

New features:

Linear incrementing timeseries
	This is an alternative to the normal linear time series. Instead of specifying the number of time points to create, specify an increment. This makes it possible to, for instance, create a time series where output is given for each day, independent of what the start and end time is.
Min and max available options for probabilistic data
	When creating an index table you can now ask for the min, time for min, max or time for max for statistics from a probabilistic simulation. For instance, show me the time for the maximum mean value, or the minimum of the 5th percentile.
Min and max available options for probabilistic data
	When creating an index table you can now ask for the min, time for min, max or time for max for statistics from a probabilistic simulation. For instance, show me the time for the maximum mean value, or the minimum of the 5th percentile.
New solver
	A new solver, RADAU5 is available.
Solver descriptions improved
	The descriptions for all solvers and the situations in which they are used have been improved.
Quick block create
	To quickly create a block in the Blocks window: Enter the name of the block in the search field. Select the type of block in the type drop down list. Select a sub-system from the sub-system drop down list. Select a category from the category drop down list. Click the button.
Debug mode for simulations
	The debug mode has been improved to not only report statistics from the simulation, but to also interrupt the simulation if any calculation is NaN or Infinity. An error message will report which block has caused the problem. Debug mode can be set from the advanced page in the simulation settings window.
General variables available in player
	There is a new screen called "Options" in Ecolego Player for selecting targets for general variables.
