TheIUTAM Bookseriespublishes therefereedproceedingsofsymposiaorganised
by the International Union of Theoretical and Applied Mechanics (IUTAM).
Every two years the IUTAM General Assembly decides on the list of IUTAM
Symposia. The Assembly calls upon the advice of the Symposia panels. Proposals
for Symposia are made through the Assembly members, the Adhering
Organizations, and the Affiliated Organizations, and are submitted online when a
call is launched on the IUTAM website.
The IUTAM Symposia are reserved to invited participants. Those wishing to
participateinanIUTAMSymposiumarethereforeadvisedtocontacttheChairman
of the Scientific Committee in due time in advance of the meeting. From 1996 to
2010, Kluwer Academic Publishers, now Springer, was the preferred publisher
of the refereed proceedings of the IUTAM Symposia. Proceedings have also been
published as special issues of appropriate journals. From 2018, this bookseries is
again recommended by IUTAM for publication of Symposia proceedings.

Preface
Co-simulation—also called solver or simulator coupling—is a frequently used
numericaltechniquetocoupletwoormoresolversintimedomain.Onemajorfield
of application for co-simulation methods is the analysis of multi-disciplinary
problems.
Usually, specialized simulation codes exist for different physical disciplines,
e.g., FEM codes for structural dynamics analyses, CFD codes for fluid dynamic
problems,ormultibodycodes forthedynamicanalysisofmechanisms.Inorderto
simulateacoupledmultidisciplinaryproblem,thedifferentcodescanbecoupledby
means of an appropriate co-simulation approach. Simulator coupling is, for
instance,successfullyappliedinthefieldoffluid/structureinteraction,forcoupling
multibody and hydraulic systems or in the analysis of electromechanical systems.
Solvercouplingmay,however,alsobeusedtoanalyzemonodisciplinaryproblems
in order to parallelize the simulation process.

(cid:129) Standardization of co-simulation interfaces, i.e., standardization of data and
model exchange.

Bringingtogetherexperts inthese different fields from many working groups from
all over the world enabled us to review the state-of-the-art, to discuss further
activities, to open problems, and to promote common research initiatives for the
future.
