Validating Fuel Cell Efficiencies
August 15, 2017
In the last decade, Polymer Electrolyte Membrane Fuel Cells (PEMFC) have seen an up-tick in popularity and practicality as OEMs and economies work to reach regional and global environmental goals. The automotive industry stands to gain the most from these technologies as PEMFC offer benefits that include: low emissions, in comparison to the archaic internal […]
Model-Based Systems Engineering for Aircraft Engines
June 27, 2017
Modelon’s Jet Propulsion Library provides the foundation for modeling and simulating jet engines along with the integrated model-based systems engineering of aircraft systems. Why start optimizing The prime mover of an aircraft, the jet engine, is one of the most important subsystems of an aircraft. Jet engines provide primary power (thrust) and secondary power (to […]
Architecture Based Vehicle Modeling
May 23, 2017
Reviewing Architecture-Based Approaches for Vehicle Modeling All Modelon libraries are developed to adhere to the open-standard, Modelica language. We, at Modelon, thrive in this language standard for many reasons and fully leverage it in the use of templates and model architectures to rapidly create models and model variants. Modelon’s Vehicle Dynamics Library utilizes this template-based […]
PowerGrab – Modeling the musculoskeletal system of the human hand in Modelica
March 14, 2017
Prehensile and precision grasps with Modelica This article can be interesting for people working with modeling and simulation of flexible multibody systems, as well as for all Modelica enthusiasts. Prehensile and precision grasps with Modelica Several years ago, while volunteering at a nursing home and observing senior citizens having trouble opening doors and holding objects, […]
Model-Based Design for Fuel Cell Systems
January 26, 2017
High fidelity multi-domain fuel cell system analysis with model based design Modelon JSME 2016 – Model Based Design for Fuel Cell Systems from Modelon Solid oxide fuel cells (SOFC) are energy efficient sources that generate zero- or low-carbon heat and/or power usually at micro scale. The generated heat/ power is consumed on-site by individuals, small […]
Real-time simulation of twist beam suspension
December 5, 2016
Application of the new flexible beam model in Vehicle Dynamics Library Industrial systems incorporate often components that are by definition and functionality flexible. Think of a twist beam axle in a car, the leaf springs or frames in a truck, the wing on an airplane and so on. In multi body simulation they are usually modeled […]
Advances of zero flow simulation of air conditioning systems using Modelica
November 7, 2016
Increased simulation robustness with systematic heat transfer coefficients analysis Simulating refrigerant loops at (near) zero flow for large vapor compression cycles is challenging due to the fast dynamics in the model under those conditions, which drastically reduce the step size of the solver. This motivated a team from Modelon together with two European automotive partners […]
Co-simulation using the open-source Python package PyFMI
September 1, 2016
Different simulation and modeling tools often use their own definition of how a model is represented and how model data is stored.
New solution for thermal power plant start-up optimization
April 28, 2016
Increased flexibility for power plants energy production During the spring and summer of 2015, a collaboration between Modelon, Vattenfall and Lund University resulted in a development of a new solution for start-up optimization of a thermal power plant [1]. The collaboration took place within the MODRIO project and was a continuation work with Vattenfall concerning […]
Integrating executable requirements to accelerate design iterations
February 18, 2016
Historically the worlds of Model Based Systems Engineering (MBSE) and Model Based Design (MBD) or Model Based Engineering (MBE) are mostly separated into disparate silos.
