Despite SI units being the recognized scientific standard, other units and unit systems are widely used to this day. Even within the metric unit scheme there are often more typical units which are preferred to match a user’s model type or preference. In addition to common alternate metric units...
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....
A point cloud is a set of data points in space where those points represent a 3D shape or object. Point clouds are used for multiple purposes including the creation and visualization of CAD models . Given our work on Carla-Autoware and rFpro, this blog will focus on the...
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...
The safety of an autonomous vehicle is paramount, but testing systems needed to ensure fully safe system performance are in their infancy. The Simulation Cycle is the process of creating, running and analysing results from a scenario. In the cycle the scenarios are designed and created by the Test Manager...
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...
Scenario Editor is a tool for the creation, modification and storage of scenarios for use in rFpro and Dymola. Scenario Editor allows users to view an OpenDRIVE map (.xodr file) and then plot a route around the road network while adding events such as stops and lane changes. For...
