KULI Usermeeting 2021 @ ECS Simulation Conference

Many things have changed over the last year and also in early 2021 things are not “back to normal”, yet. So, in order to facilitate your participation at our bi-annual KULI Usermeeting, we have decided to make some adaptations to the established format:

  • This year’s usermeeting will be an online event. For you this means participation without travelling effort or travel restrictions… and taking part will be free of charge! Accordingly, the range of participants will be even larger and more diverse than ever before… we expect people to join from all over the world. And we are currently working on a conference platform which will allow you not only to listen to presentations, but also to engage in “one to one” discussions with us or with other participants.
  • The second change is that we have decided to join forces with our other software products at Engineering Center Steyr and launch our new conference format, the “ECS Simulation Conference”. There will be several parallel sessions, so the choice is yours, whether you want to experience a “classic” KULI Usermeeting… or if you are tempted into some of the interesting talks in one of the parallel streams.

The ECS Simulation Conference will take place on May 19th and 20th, invitations and calls for papers have already been sent out and it looks like it is going to be a great event with a quickly filling agenda. If you have not received an invitation and if you want to participate or even contribute… please contact us via our e-mail address kuli.support.mpt(at)magna.com or register directly at our conference webpage.

KULI 14.1 – A new era of user assistance

For you as a KULI user, version 14.1 offers interesting new features and a lot of improvements. A completely new output window and a better support for many output data stand out in particular. The improved support for a dual monitor mode is also noteworthy.


Output Panel

The new Output Panel replaces the existing KULI Message Panel at the bottom of the main window. It collects all messages relevant for the user while working with KULI and especially during the simulation. It prepares messages so that finding information is a breeze. You have extensive filter and sorting options available and you can also keep the messages across simulations so that you can access them again later.

Users with two monitors can use the functionality to float the Output Panel and move it to a second screen. Users with only one screen or a low monitor resolution can benefit from the fact, that they can now completely hide the output window to maximize the content the KULI main window. The output window can be shown again if necessary. You can find detailed information in the KULI Online Help under  https://kulihelp.magna.com/km/14.1/kuli-base/output-panel 


Support for a huge amount of output data

KULI models generating many result data are now fully supported. From now on there is no longer any known limitation on how large the output file can be.

Improvements for Plate heat exchanger

The plate heat exchanger in KULI has undergone an extended revision. These include, for example:

  • Showing the right channel height in case of changed number of plates in the parameter window.
  • A more responsive component window and immediate results during the calibration process.
Updates in Dynamic Solver circuits

Some notable improvements have also been made in the dynamic solver:

  • The initialization temperature for a Plate Heat Exchanger in transient simulations is now considered correctly.
  • Radiators are now supported which specify the heat transfer coefficient in the heat transfer table.

There are also improvements like

  • a better handling when a medium is missing,
  • enhancements when using the file actuator for an N-dimensional map, 3D map and characteristic curve,
  • a significantly reduced simulation time for transient AC simulations and an activated AC phase diagram window
  • and many others…

The full list of modifications can be found in the release notes for KULI 14.1.

Extended KULI online content

In times of the corona pandemic, the content on online platforms is of particular importance. We want to support you as KULI users in these challenging times with additional content on our homepage. This includes a revised KULI knowledge base, learning videos for our KULI tutorial, additional examples in our online library, but also exciting and interesting lectures by professional KULI and thermal management experts.

New KULI Knowledge Base

The KULI knowledge base has been completely renewed. It now offers a powerful search that also includes the KULI online help. Many entries have been updated and others have been transferred to the KULI Help. Also new ones have been added. For example, one focus was placed on additional support for license handling. There are now videos that explain the setup of an LM-X server in detail or one that shows all the steps necessary to borrow a KULI license from an LM-X license server.

In the future, new content will be added continuously so that you can find answers to questions about KULI as quickly as possible.

You can find the new KULI Knowledge Base in KULI Online Help. 

KULI tutorial videos

In order to get into KULI even faster, we are now making some selected chapters of the KULI tutorial available as learning videos (https://kuli.magna.com/support/kuli-e-learning-videos). These enhance the textual tutorial (https://kuli.magna.com/download/documentation​​​​​​​) with additional information, which makes it even easier to get started with KULI.

In order to continue to support you in the best possible way, we will also be constantly expanding the online offer with new learning videos. So, visit our homepage from time to time so that you do not miss any new content.

New additions KULI Online Library

The KULI Online Library is consistently being updated with new examples. So in the last few months examples were added for the following topics (among others):

  • Subcooling controlled EXV: An example that demonstrates how a subcooling controlled expansion valve can be modelled. The signal path based technique presented in this example can be applied in several other applications as well.
  • PID controller optimization: An example that demonstrates how a Python script can be used to optimize a PID controller in a KULI model.
  • Expansion tank: An example showing possibilities to model an expansion tank.
  • Transient parameter variation: An Excel script showing how transient parameter variation can be set up efficiently.

The Online Library has a powerful search function such that you can easily find examples for the topic you are interested in. It contains small subsystems, full-featured models, scripts, and more. And it can easily be accessed via a single click from within KULI using the main toolbar.

Upcoming Online Seminars

One new and very successful format we have established last year in June is our “Online Seminar” series. So far more than 300 participants from all around the world have joined us for discussions about different topics ranging from general thermal management issues to specific KULI modelling suggestions. And the series continues…

  • The next online seminar will have the title “Getting the most out of thermal simulation results” and will help you with the important task of postprocessing and analysing the findings from your KULI simulations. Dates will be available on February 23rd (09:00 CET), 24th (13:00 CET) and 25th (17:00 CET) to provide convenient times for all time-zones. You can still register for free.
  • In March we will hold an online seminar about using sensors and actuators in KULI, details will follow in the next weeks.

Future topics on our list include heat pumps, control strategy development, a focus on modern valve types (and how to use them in KULI) and fuel cells… so it is not going to get boring any time soon. Stay tuned!
