This blog post will introduce newcomers to the difference between using co-simulation FMUs (Functional Mock-up Units) and Model Exchange FMUs. FMI – Functional Mock-up Interface FMU – Functional Mock-up Unit (a model, for example, which has been wrapped within the Functional Mock-up Interface). For more information on FMI please...

Calculate partial derivatives of a Modelica model in Dymola.
This post describes how to modify the windows setup so double clicking on a .fmu file opens it in Windows explorer as if it were a zip file. This post is based on https://superuser.com/questions/1133475/how-to-register-a-new-zip-file-extension-on-windows-10 with minor modifications to work with the .fmu file. This will require the user to...
Virtual scenario based testing Committed to providing a new generation of autonomous vehicle simulation tools, the new Autonomous package of Modelica vehicle models is the latest product from Claytex designed to help you bring cutting edge Automation ideas into reality. Aimed at helping to create lean, fast-simulating, scalable, vehicle...
In my previous entry on the Claytex blog post, I explained how to export FMUs for Co-Simulation with inline integration settings. For most users, this would suffice, however for users wishing to export source code CoSim FMUs with Inline Integration, the methodology required is slightly different. At first glance,...
Model export is a commonly used function of Dymola. Exporting FMUs using the FMI interface is one of the most popular options, as it enables users to utilize the in-built FMI specified functionality for parametrization, time integration and other functions. Even though FMI was primarily developed to promote model...
This blog post looks at exporting models as FMUs containing string parameters and modifying those string parameters in the FMU before simulating. Process for creating FMUs with string parameters and modifying these strings The basic instructions for creating an FMU containing modifiable string parameters are below: Make sure the...
Dymola 2019 is now out and there are many new features that have been added to this new release. More information on these can be found in the official Dymola 2019 Release Notes. DAE mode for more efficient simulation of large models Improved initial guesses for equations in the...
The FMI Blockset for Cloud allows co-simulation FMUs to be simulated in the cloud using a REST API. By deploying this as an Amazon Lambda Function we can build powerful and flexible simulation applications that provide a browser based user interface. The goal is to provide a simulation platform...
