Welcome Message

Following the first successful conference in 2016, the 2nd Japanese Modelica Conference takes place in
Tokyo again. With this effort, we hope to create an arena in Japan and Asia for sharing knowledge and
learning about the latest scientific and industrial progress related to Modelica and FMI (Functional
Mockup Interface). We are now proud to present a conference with:
• 3 Keynote speeches
• 37 paper presentations
• An exhibition area featuring 9 exhibitors
• Great venue location in the heart of Tokyo
According to Modelica Association standards, all papers are peer-reviewed and will be freely available
for download.
We want to acknowledge the support we received from the conference board and program committee.
Special thanks to our colleagues at ANSYS Inc. and ANSYS Japan K.K. for taking care of all the
practical matters. Support from the conference sponsors is gratefully acknowledged. Last but not least,
thanks to all authors, keynote speakers, and presenters for their contributions to this conference.
We wish all participants an enjoyable and inspiring conference!
Tokyo May 17,

Sameer Kher & Yutaka Hirano

10 Years of FMI: Where Are We Now, Where
Do We Go?

The exchange of simulation models is a key
enabler for the distributed model based
development and verification process. This
was the main motivation to start the
MODELISAR project 10 years ago. The main
result of this research project funded by the
European Union was the tool independent
Functional Mock up Interface (FMI) for Model
Exchange and Co-Simulation, which is now
maintained within a Modelica Association
Project. By now more than 100 tools support
FMI. The presentation provides an update on
the current status, planned new features and the
roadmap towards a new release. A few
examples demonstrate typical FMI use cases.
As an outlook some related ongoing research
projects like ACOSAR and EMPHYSIS are
presented.
