Here at Claytex we release our Modelica libraries at least twice a year; this process includes exporting encrypted copies of libraries to protect them, and ensuring all accompanying files are supplied to users. As we do this regularly for a large group of libraries, we’ve streamlined the task of...
Dassault Systemes have announced the availability of a new version of Dymola. The key highlights of Dymola 2022x release are: Additions and improvements in Dymola Visualization of Modelica class hierarchies Steady state solver interface Improvements of plotting Improved warning for unconnected physical connectors Improvement of the explicit Runge-Kutta solver Option to activate parallel Jacobian...
A lesser known feature in Dymola is the ability to simulate a model that has inputs and assign the inputs from signals stored in the dsu.txt file. This is a useful feature when replaying models used in hardware in the loop testing. Simulating a model with unassigned inputs If...
Fig. 1: Virtual testing of an autonomous vehicle in rFpro Whether flying, driving, using a power socket or even dining in a restaurant, we take safety for granted, because we trust the safety processes behind it. Food freshness is regulated and inspected, electrical systems are equipped with circuit breakers,...
One advantage of Dymola and Modelica which is often talked about is the ability to build flexible and adaptable models. Models that, with the minimum preparation, can be used for a different task or have their effects change swiftly, following a simple reparameterisation. But how is that achieved? This...
EV manufacturers are turning towards total vehicle simulation technology to assist inefficient development of vehicles. If automotive OEMs can be provided with the information to understand and quantify vehicle designs, as well as conceive and calibrate software before a single prototype is created, then waste is reduced and better designs...
There is a Python interface with Dymola shipped with every version of Dymola. Users can control Dymola with a wide variety of function calls that can load, create, simulate and read results from Dymola models. But when a limited number of licenses are available it can be very inefficient...
In the Dymola compilation process the Modelica model is translated and a dymosim executable file is created. This blog post looks at how this dymosim executable can be called directly from the Windows cmd or from the Linux terminal. This information is in the Full Dymola User Manual Section...
Autonomous Vehicle Safety Series (AVS #) The industrial application of Automated Vehicles is becoming ever more feasible. As the excitement of innovation wanes, the safety and reliability become the focus. Delivering a reliable and safe AV service can be achieved, when a safety-oriented culture creates an environment where multiple...
One of the benefits of VeSyMA, and simulation in general, is the ability to answer “what if” questions using predictive models in experiments such as drive cycles. Sensitivity testing is a common and effective method of study. One parameter of a model is varied, with all others kept static,...
