Modellus X 0.1 Release Candidate

(Update: Modellus new site is

Finally, after months of my spare time that amount to years, I’m finally able to release a version of my hobby project Modellus X 0.1 that I consider suitable for public release. For those who do not know Modellus, it is a free software used mainly to help in the education of sciences. On a more technical level this is a Swing with embedded JavaFX app.

This is a release candidate meaning it is very near the final version, the only thing that is missing is translation to other languages (other than English(UK) and Portuguese(Portugal)) and this is where I would ask for your help, if you think you have the capability of translating to other languages/locales that are missing than please contact me, full credit will be given and the Modellus community will be very thankful to you. Also feedback and bug reports would be very helpful.

This version can load all models made on previous versions 4.01 and 4.5.

You can temporarily get it here: Modellus google code download page You can also get previous Modellus versions examples from there. I’m currently also finishing a new site ( wish will better serve the community. It will be the future home for all things Modellus.

There will be Windows 32, windows 64, mac and linux releases of the final Modellus X 0.1.

Going forward I expect to make public releases more often, not more than a couple months or so.

I hope you enjoy using  it as much as I enjoyed developing it.

Modellus 5 beta – Selecting an image from disk for the particle










(Update: Modellus new site is

To keep users updated on the new features being added and upcoming on Modellus 5, I’ll be producing a series of videos and blog posts.

For the videos I’ve created a youtube channel: and for the posts I’ll currently do them here but in the near future a new blog will be created which will be the focal point for all Modellus news, activities, community news, etc.

First up on this series is “selecting image from disk for the particle”, this new feature which should have probably be already included and will certainly come in handy, allows a user to select an arbitrary image from disk to represent the particle, the video of this feature is here:

I’ve been working hard on my spare time with the help of Albino Rafael ( which is doing all the user testing,  and hope to have a public release soon. Two more features and it will come out, these are controller pause/stop conditions (which I’ll start doing next) and video analysis.

First we’ll have a public preview release so translations to other languages may start and shortly after the Modellus 5 final release.

Modellus 5 beta 1 release

(Update: the new Modellus site URL is

Modellus 5 beta1 is available for download here. This version should be extremely usable.

Unpack files and run Modellus5.jar through the JVM (Java 1.6 update 20 is the minimum requirement). This is the PC version, I suspect some things won’t work on Mac and Linux although I haven’t tried it yet.

Modellus 5 is free. It is primarily used to aid teaching. By using only a mathematical language (no need to learn any new language) students and teachers are able to create models which then they can interact/view using animations/graphs/tables, etc.

From a technical standpoint, this version was created using javafx and swing. The animation window (background) was done in javafx while all the rest is Swing.

I’ll be posting more information about this version, shortly.

There are some examples you can try: here and here these are Modellus 4 examples though, they don’t use version 5 new features.

Let me know of any bugs you encounter or feature requests.
