What’s new in 24.2.0

We have seriously updated the documentation - we have changed the structure of sections. Everything related to calculations is now in the Calculation Environment section, and everything about modelling and simulation is in the Modelling and Simulation Environment section. The sections have been tidied up as well - we’re sure you’ll like it.

We’ve also added some useful articles for both beginners and advanced users; the full list is below.

We have redesigned the appearance of the Engee window tabs. In our opinion, it’s much prettier.

We also added an option to enable vertical tabs if you have too many tabs:

At your request we have added the ability to enable a dark interface theme, but for now in experimental mode.

You now have the opportunity to upload your notebook, which is written in Python, to Engee and run it in the script editor. We recommend using the Jupyter magic commands to install the necessary packages:

This will display the variables from Python in the workspace (you will see that they are of type PyObject).

MAT is a familiar file format for MATLAB users, which contains variables, functions, data arrays, and so on. 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 have given the option to collapse such outputs into a more compact form.

Completely redesigned the autosave menu for interactive scripts in the editor. By default it is off, but you can adjust it as you like.

One of the features that many people are waiting for is the model reference. These models are used to create the hierarchy of a system model. Model references are ideal for subsystem usage, unit testing, parallel builds and large systems. Look for the Model block in the library.

Annotations have been improved:

You can now run models with unconnected blocks and lines on the canvas. This is useful for debugging models and performing virtual tests, and reduces the routine when developing multi-variant 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 your model.

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

Your Engee workspaces will now be preserved when you switch to different models. That is, open service menu windows 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 rapidly. Therefore, many small steps are performed in the vicinity of discontinuity points where the variables change abruptly. This often leads to a drop in the speed and reliability of calculations, as well as negatively affects their accuracy.

In Engee, the ability to incorporate a specialised event detection algorithm has been added to localise discontinuities more accurately without the overhead of excessively small integration steps. It improves computational accuracy and, in many cases, speed and reliability. Turning off 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 when other modes are not suitable for some reason.

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