The possible settings are:
| Setting | Explanation |
|---|---|
| Number of iterations | The number of iterations. The number of model evaluations is derived from this value. |
| Number of Fourier coefficients | The maximum number of Fourier coefficients that may be retained without interferences between the assigned frequencies. |
| Seed | The seed used by the random number generator. If it is Auto, a random seed will be used each time. |
The possible settings are:
| Setting | Explanation |
|---|---|
| Percentage | |
| Model evaluations | The number of times the model will be evaluated. |

A block is an Ecolego name for the components used in the construction of the model and can be shown in the interaction matrix.
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.
Wednesday/Thursday - Advanced Ecolego.
Friday - Ecolego applications
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.
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.
This update fixes minor bugs related to the library and copy/paste.
New features:
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:
| |
| 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. | |
We would like to invite you to the annual Ecolego workshop in Stockholm.
Day 1,2: Crash course in Ecolego usage. Basic training for people that have not participated in earlier Ecolego workshop training or feel like they need to refresh their knowledge.
Day 3: Training in all new features of Ecolego 5. Become an expert in unit checking, building libraries and in committing projects to version control.
Day 4: Presentation of Ecolego use-cases. By workshop delegates and Facilia staff. Have you been involved in an interesting application of Ecolego? Let us know and you can present your work this day.
Day 5: Problem solving and customer specific assistence. Bring your modelling headaches and questions and we will solve them together.
We suggest the following two alternative dates.
May 24th-28th
June 7th-11th
If you are interested in joining the workshop, please let us know the dates for which you are available. You can select the dates here.
Please let us know before April 30th if you wish to participate.
