The 4th International Symposium on Phase‑Field Modelling in Materials Science (PF 19), to be held at the Ruhr-Univerität Bochum / Germany, is intended to provide an excellent forum for the growing phase-field community. We aim to cover a broad field of theoretical modelling, numerical methods and applications related to phase-transitions, moving boundary problems, pattern formation and microstructure evolution in general. Also model integration into a multi-scale, multi-physics framework are of high interest. The covered topics include:

We would like to discuss latest advancements and future directions for these approaches, hence contributions covering unpublished results or work in progress are particularly encouraged. We also highly appreciate contributions dealing with the experimental validation of models named above. We expect that a wide range of applications, from solidification to fracture, phase transformation and microstructure evolution in general, polycrystalline and multiphase materials, hybrid materials, functional, and biological materials will be covered.

PF19 OpenPhase Tutorial

After PF 19 conference on Friday, 26th July, interested conference attendees have the opportunity to take part in the PF 19 OpenPhase Tutorial cohosted by ICAMS and the OpenPhase Solutions GmbH. The PF 19 OpenPhase Tutorial provides a short introduction to the open source phase-field software OpenPhase, hands on examples and talks from current, scientific work using OpenPhase. At the event there is the possibility to get in contact with the developers of the software as well.
Maximum number of participants: 40.

If you are interested please register by e-mail with your full affiliation including taxnumber (VAT).
Registration mail:
The price including Thursday afternoon dinner and coffeebreaks is 175,-€ per person.

Abstract Submission

Deadline for abstract submission has passed.


Registration for the 4th International Symposium on Phase‑Field Modelling in Materials Science (PF 19) is closed.


The symposium will take place in the Conference Centre of the Ruhr-Universität Bochum. It is located at the main campus below the mensa. It can be easily reached by public transport. A limited number of parking spaces is available in the nearby P9.

Travel Information

By public transport

Bochum Central Station is served by ICE, IC, EC, regional, and suburban trains at a high frequency. From there, you can reach us easily by taking the underground line U35 (CampusLinie) straight to the Ruhr-Universität Bochum (RUB), which has its own station named after it. The U35 (direction Bochum Hustadt) runs at five-minute intervals on weekdays and takes just ten minutes to get to the university.

By car

Motorists can also easily reach the RUB via the dense network of motorways in Germany and especially in North Rhine-Westphalia. The quickest route is via the motorway junction Bochum/Witten, where the A43 and A44 meet. Simply take the exit Bochum-Querenburg, follow the signs “Ruhr-Universität” and then the (electronic) information boards.
A limited number of parking spaces is available in the nearby P9.

By plane

Three major airports – Frankfurt, Cologne/Bonn, and Düsseldorf – are within a reasonable distance of Bochum. Düsseldorf Airport is the closest and most easily accessed one: there are direct connections between the airport and Bochum’s main train station up to eight times per hour, and the journey only takes around half an hour. From Frankfurt airport, you can reach Bochum within two hours by Intercity Express trains (ICE).
