In this blog post I’ll look at how you can compare animations generated by two different experiments. If you are simulating your model with different parameter settings, it can be very useful to compare the animation results as first pass to see what difference your parameter changes have made...
Carrying on from the previous post on the Introduction to System Modelling Before Building Models, which details preparing to build a system, this post will focus on what to consider when building models and systems. Where to Start? It can be very difficult to know where to start making...
This post has a closer look at the different inlining options: Inline, LateInline and InlineAfterIndexReduction as described in the Modelica Specifications in Section 8.3. The post describes how these inlining options differ and gives some extra details about how this inlining has been implemented in Dymola. What is inlining?...
In this blog post I look at the Dymola setup settings, how you edit them and where they are stored. There are lots of options available to personalise your Dymola setup; I won’t cover the detail of all the settings here, but by knowing where to edit them and...
This is the first in a series introducing the best approach, preparation and practice when system modelling. This post specifically investigates what you should consider before you start modelling. Modelling a system can be a difficult task to get right. There are many things to consider before approaching a...
Eagle eyed users will immediately notice that this year’s second release of Dymola breaks with the usual naming tradition; gone is the FD01 designation, in is the “x” nomenclature, but that’s not the only thing to change. The user GUI has undergone a complete overhaul, modernised to render a...
Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of the Dymola 2020x release are: New user interface The user interface of Dymola has been modernized to the benefit of both novice and experienced users. The new interface provides easier access to all operations and has been re-grouped to...
In a prior post, I wrote about manually specifying derivatives of a function in Dymola. This is necessary in certain cases, especially when external code is used. For the simple function I used in that post and many functions like it, however, there is actually a much easier answer....
Here are a couple more Dymola tips and tricks that you may want to incorporate into your daily Dymola work. Mark a model as the ‘Simulation Model’ How often has this happened to you? You’re modifying a sub-component of your simulation model and once you complete the change, quickly...
While developing libraries there are many ideas that dawn on me that are normally accompanied by the phrase “How hard could it be to….”. This is the result of one of those thoughts. While developing ground contact models for our VeSyMA – Motorsports, 1D and 2D tests were created...
