Simscape Simulation Results Explorer

Tool for navigating and plotting Simscape™ simulation data, created in MATLAB® code

Description

This file creates an interactive GUI for navigating and plotting Simscape simulation data. You can navigate the simscape.logging.Node object using a tree browser, and the data is plotted for you automatically. This makes it easier to plot the different physical quantities in your network without using sensors.

To use this file, simply pass the simscape.logging.Node object to the function:
>> ssc_explore(simlog)

This is a significant improvement to the usability of Simscape, and an encouraging sign that Simscape will continue to develop.

As well as the obvious productivity improvement, this will help modelling accuracy because the ability to browse all of the logged data using the tree encourages critical examination of all of the activity inside the model, rather than just the signals which have signal converters chosen by the user.

I look forward to the ability to define default "human-friendly" units for the various quantities in a future release. Certainly for hydraulics, "m3/s" and "Pa" are difficult for engineers to relate to.

Niall,

Thanks for the feedback. I'll keep this in mind for future updates. I provided this functionality in MATLAB Central so that the community can modify and improve the implementation and submit changes back to MATLAB Central for others to use.

The underlying simscape.logging.Node object provides unit conversion functionality so plotting in "human-friendly" units is supported by the underlying object. It is also simple to implement: all you need to do is define a list of "human-friendly" units and then in the localPlot function extract the values in "human-friendly" units if such units exist for the quantity being plotted. Everything else should work just fine.

Thanks,
-Atul

Without this tool, I wouldn't be using Simscape logging. The Results Viewer should be incorporated into product releases :).

Nice work!

[Roni Peer]

Wow.
One of the most useful files I've ever found here.
Nice Work!

[Eric]

can someone give me a more detailed explanation of how to set this tool up? I am not sure what is exactly meant by "To use this file, simply pass the simscape.logging.Node object to the function:
>> ssc_explore(simlog)"

THANKS!

Very useful tool. However, English units are incorrect.

e.g. simscape doesn't have a "lb" or a "F" (temperature) defined unit . Changing lb->lbm and F->R gives me the correct behavior.

Hi there

I have a dataset that would be best inspected via a tree structure. The labels can be broken into something like a tree. I was hoping to use this tool. Is there a way that I can generate a SimScape logging node without actually using Simulink, but creating a node from the data?
