Modellus is used to introduce computational modeling for allowing an easy and intuitive creation of mathematical models using just standard mathematical notation, for having the possibility of creating animations with interactive objects that have mathematical properties expressed in the model, for allowing the exploration of multiple representations and for permitting the analysis of experimental data in the form of images, animations, charts and tables. Modellus focuses on modeling and on the meaning of models.
It has been published in different languages (Portuguese, English, Chinese, Greek, Spanish, ...) and it is used in all over the world with samples ranging from Physics to Mathematics, going through Mechanics, Chemistry, Statistics, Algebra, Geometry, among others.
Stop conditions and "if" in current Modellus X 0.4
There has been several people asking me how to create stop conditions and "if" statements in the current version of Modellus.
"If" statements have been replaced by mathematical conditions - "condition" buttton in model task, and as for stop conditions they are not yet available but you can emulate them.
The following modellus file: stopConditions.modellus illustrastes a simple example of emulting stop conditions and using conditions. It moves the particle according to "y=cos(x)*50" as long as t < 30.
Ha habido varias personas que me preguntan cómo crear condiciones de parada y "if" en la versión actual de Modellus.
Declaraciones "if" han sido sustituidas por condiciones matemáticas - buton "condición" en el modelo, y en cuanto a las condiciones de parada que todavía no están disponibles, estas pueden ser emuladas.
El siguiente archivo Modellus: stopConditions.modellus ilustra un ejemplo sencillo de emulación de condiciones de parada y el uso de condiciones. Se mueve la partícula de acuerdo con "y = cos (x) * 50", siempre que <30.
Modellus now also in Czech
New Modellus version is now available for download. This is a minor release:
- Czech language now available - thanks to Martin Krynický
- Fix: German language was not available
Modellus X 0.4 released
A new major release is available. This puts Modellus X in its 0.4 version.
New developments since the previous release:
- Animation window is an infinite world (bounded by the largest number a computer can store - of type double)
- Toolbar in animation window that allows you to: pan through the world, zoom in, zoom out
- New language: German. Thanks to Frank Dietrich.
- Updated translations
- Bug fixes
The next version will focus on:
- Performance improvements - performance tunning has never been made before, so there is a lot that can be improved in this area.
- Charting - more types of charts and improving existing ones.
Thank you, enjoy.
