What’s new in 24.2.0

We have seriously updated the documentation and changed the structure of the sections. Everything related to calculations is now in the section Calculation environment, and everything about modeling and simulation is in the section Modeling and simulation environment. We’ve also put things in order inside the sections — we’re sure you’ll like it.

And we also added some useful articles — how to beginners, and for advanced users; full list below.

We have redesigned the appearance of the Engee window tabs. In our opinion, it has become much more beautiful.

We’ve also added the option to enable vertical tab placement if you get too many of them.:

At your request, we have added the option to turn on the dark interface theme, but so far in experimental mode.

Now you have the opportunity to download your laptop, which is written in Python, to Engee and run it in the script editor. We recommend using Jupyter magic commands to install the necessary packages.:

At the same time, variables from Python will be displayed in the workspace (it will be visible that they are of the PyObject type).

MAT is a well—known file format for MATLAB users, which contains variables, functions, arrays of data, etc. Now you can import files of this format into Engee, as well as export variables to it.

Sometimes the output of a function takes up a lot of space in the script editor, so we made it possible to collapse such outputs into a more compact form.

The auto-save menu of interactive scripts in the editor has been completely redesigned. It is disabled by default, but you can configure it as it suits your needs.

One of those features that many are waiting for is the link model. Such models are used to create a hierarchy of the system model. Reference models are ideal for subsystem reuse, unit testing, parallel builds, and large systems. Look for the Model block in the library.

Updated annotations:

Now you can run models with unconnected blocks and lines on the canvas. This is convenient for debugging models and conducting virtual tests, and also reduces the routine when developing multivariate models.

With the new release, you don’t have to guess in which order the blocks will be executed in your model. A new setting in the debug menu allows you to build and display this order on the model.

Expanded the list of actions on the model for which callbacks are performed (first introduced in the previous one release). It will be even more convenient to use them.

Now, when switching to different models, your Engee workspaces will be saved. That is, the open windows of the service menus will close and open depending on the model you are working with.

Made several improvements to the Data Inspector:

Variable step solvers dynamically vary the size of the integration step, increasing it when the variables change slowly and decreasing it when they change quickly. Therefore, many small steps are performed in the vicinity of the break points, where variables change dramatically. This often leads to a decrease in the speed and reliability of calculations, as well as a negative impact on their accuracy.

Engee has added the ability to enable a specialized event detection algorithm that localizes gaps more precisely without the overhead of unnecessarily small integration steps. It allows you to improve the accuracy of calculations, and in many cases, speed and reliability. Disabling the algorithm may allow the calculation to be completed faster, but at the cost of a significant drop in accuracy. The third mode with discontinuous functions, described in the first paragraph, is recommended to be used only in cases where the others are not suitable for some reason.

We spent a lot of effort on refining the custom block Engee Function:
