When debugging a model, a de-cluttered messages log window makes it easier to identify what the important/critical problems are that Dymola has found with the model. How can we de-clutter a log window though without loosing valuable information Dymola tells us about the model? There will be text in...
A new training course has been developed to allow students to use the Python Interface with Dymola. The interface, shipped with Dymola, is freely available to use. The half day course focuses on the basics of how to use the interface effectively in any application. Setting up the interface,...
The solver tolerance determines the accuracy that the states in the model are solved within. This post has a closer look at what tolerance is, how the tolerance used in Dymola effects the accuracy of the results and how you can effect the tolerance of a given signal. For...
This blog post is a continuation from a previous post on the Modelica Language. This blog post focuses on the syntax used in equations and algorithms and the difference between the two. Calculations Equation Sections Models and blocks primarily use an equation section to define the calculations of the...
This blog post is a continuation from a previous post on the Modelica Language. This blog post goes into a little more detail regarding variable definition and syntax in equations and algorithms. The Class Restriction of a class can restrict the ability to use certain elements and methods, also described...
Once you’ve got comfortable with creating models using components in the Diagram layer you will probably need to create your own models. This requires understanding and implementation of the Modelica language. This, like any other coding language, must be written in the correct order, with the correct punctuation. This...
There are lots of reasons why a model can fail and sometimes it feels like an endless battle just keeping models running. But what do you do if there is a model that used to run and for some unknown reason it just doesn’t any more? Or a model...
