OpenModelica is a unique large-scale integrated open-source Modelica-and FMI-based
modeling, simulation, optimization, model-based analysis and development environment …

Dynamic simulation of district heating and cooling networks has an increased importance in
the transition towards renewable energy sources and lower temperature district heating …

This paper summarizes the final research results of the ITEA3 project EMPHYSIS
(embedded systems with physical models in the production code software). Its core …

Equation-based modelling is a powerful approach to tame the complexity of large-scale
simulation problems. Equation-based tools automatically translate models into imperative …

Digital twins (DTs) are enablers for the fast optimization processes required in the Industry
4.0 context. Declarative equation-based modeling languages, in turn, enable the creation of …

This article presents a matching algorithm for bipartite graphs containing repetitive structures
and represented by intension as Set-Based Graphs. Under certain conditions on the …

This paper presents the a set of multi-domain load models that allow simulating the
dynamics of coalesced electrical power and the thermo-fluid system by exploiting the …

This Work-In-Progress paper introduces HiPerMod, a new Modelica benchmark suite for
large-scale models. The main characteristic of this benchmark suite is that for each model …

This work introduces a novel methodology for transforming a large set of connections into
the corresponding set of equations as required by the flattening stage of the compilation …

We are investigating ways of introducing just-in-time compilation in a standard-compliant
Modelica compiler, the Open-Modelica compiler (OMC). The main motivations are enabling …
