What’s new in 26.8

The Simulink model converter has been significantly improved. This makes it faster and easier to convert Simulink models to Engee. For unsupported blocks, stub blocks with already configured ports are added to the converted model. The stub blocks are highlighted in red. These are the blocks Engee Function therefore, they can be adapted to your needs.

An error message is displayed in the code of the stub block when starting the simulation, so that it cannot be overlooked.:

Also, now the model conversion script does not finish its work on unsupported blocks, but completes the conversion. This allows you to see the entire structure of the model, even if it contains unsupported blocks.

Appeared in the documentation new section with examples on electric drive. The first full-fledged projects have already been added, which show how to Engee to model not a single component, but complex technical systems as a whole. An electric drive is one of the good examples of this approach: its modeling uses electrics, mechanics, control, power electronics, and object dynamics. Therefore, it is convenient to study not only individual features on these models. Engee but also how full-fledged engineering systems are assembled from them. This is just the beginning. The section will be regularly updated with new models, and the set of tasks will expand from basic components to more complex electric drive systems.

Not every user Engee understands numerical methods. We understand this and are constantly striving to simplify the configuration of solvers and automate the selection of their parameters for the task. For example, in the absence of continuous states in the model, there is no point in using other solvers other than a specially optimized discrete one. And when choosing the calculation step, you need to take into account the discrete frequencies and continuous periodic signals presented in the model, make sure that the solution does not degenerate into two points, etc. Separately, it is worth noting discrete models with a constant pitch. If earlier you had to manually select the calculation step so that it was an integral divisor of all discrete frequencies in the model, now Engee performs the selection independently, which greatly simplifies the work, especially when adding a new frequency to the model. The status bar at the bottom of the screen now displays the name of the solver actually used and the step — constant or maximum — with which the calculation is being performed.

United Model Data Editor and Physical signals in one module. Now the main tools for working with model data are in one place — you don’t need to search for them in different sections of the interface.

Added a new specialized library of blocks for modeling automotive systems. It includes ready-made components for the internal combustion engine, suspension, body and wheels. Now typical elements of automotive systems can be assembled from ready-made blocks, without creating each subsystem from scratch. The library will definitely be replenished.

Starting in the spring, we continuously profiled abnormally slow models all summer and worked on optimizing their performance. We are pleased to present the improvements that have been included in Engee During these months:

Now you can select the color of the signal on the graph using a full—fledged palette picker, just like in graphic editors. You no longer need to limit yourself to a fixed set of colors from ready-made palettes: you can choose any shade for each signal and customize the graph to suit your needs.

Now the source code of each block is C Function and Engee Function it opens in its own code editor window. The title of the window shows the names of the block and the model to which it belongs. This makes it easier to work with multiple blocks at the same time: you don’t have to switch between them in the same editor and guess which code is currently open.

The names of signal visualization graphs and axis signatures have been redesigned. Now they don’t move when the font size increases, they scale and center appropriately. In general, it has become much prettier and neater.

We have released documentation and examples to create custom embedded system support packages (targets). This is important for advanced users who want to develop their own targets. The documentation describes the stages of target development and the necessary APIs.

We have provided examples of two targets.:

This is a great milestone in the development of embedded system support packages in Engee and we can’t wait to see how you use it.
