How to export CoSim FMUs with Inline Integration – Part 2 – Source code edition
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,...
How to export a CoSim FMU with Inline Integration – Part 1
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...
Using string parameters in FMU models
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...
