Here at Claytex we typically release new versions of our Modelica libraries twice a year inline with the Dymola releases; allowing us to regularly provide our users with new features, enhancements and bug fixes. The changes between versions of our libraries may include changes of names, parameterisation or locations....

As mentioned previously on the Claytex Tech Blog, the trajectory file is the result file format of Modelica. At first glance, it appears to be a standard .mat file. If you have ever tried to open it, then you will have seen that it is not! Results data is...
This blog post seeks to clear your doubts on managing libraries and models. When should we Load or Open a library? When should we use Save All, Save or Save Total? Using the right option for what you are wanting to achieve can save you and other colleagues and...
Like many programs, Dymola makes use of a working directory on your computer. Dynamically associated with Dymola, it acts as a location to write files required by Dymola. By virtue of being dynamically linked to Dymola, the working directory is very much a living part of the Dymola process....
Following Adam’s great Introduction to the Scenario Editor, the next step is to use the output to create a simulation. For that I need to elaborate on the test sequence driver. The test sequence driver is found within VeSyMA – Suspensions and is a type of closed loop driver...
This post looks at automating pre-processing of .mat files within the Modelica model. Differing formats Occasionally the data you have is not in the format required by the Modelica model. So, the data will have to be pre-processed. This can be done by pre-processing all the data. Alternatively this...
When developing a model, I often simulate and analyse the same experiments repeatedly. When you are doing this over and over it can become really tedious to create the same plots from scratch every time. Also, when you are sharing your Dymola experiments with colleagues, it can be difficult...
A model that does not run is very frustrating. Troubleshooting non-model related Dymola failures can sometimes be difficult. If the model code itself is valid, then a separate issue is causing failure. In this post I will outline some typical issues we have seen through support questions here at...
Before getting involved in advanced ways of modelling we need to make sure the basics are in place. The better we set out the class in the first place, the easier our lives will be later on in the modelling. I have written blog posts in this area in...
If you haven’t experienced the benefits of using the correct tool for the job or the tremendous impact targeted training can have to rapidly increase your knowledge and exploitation of the software, a phrase that is often heard is that “software and training are expensive”. In my view, that...
