Course description

The course will concentrate on theory and practice of topology design. Topics include:
- Design parametrization (interpolation schemes, composites, etc.)
- Sensitivity analysis (direct and adjoint methods)
- Algorithms (OC-methods, convex approximation schemes and other methods)
- Computational issues (checkerboards, filters)
- Applications in structural and multi-physics problems (industrial examples, MEMS-MicroElectroMechanicalSystems, wave-propagation problems)

Registration etc:


Registration to:
DCAMM-TopOpt course secretariat, att.: Anna Jensen, Department of Mathematics, Technical University of Denmark, Building 303, DK-2800 Lyngby, Denmark. Phone: (+45) 45253031, Fax: (+45) 45881399, E-mail: A.Jensen@mat.dtu.dk.

Registration fee:
There is no registration fee for students enrolled at universities and public research institutions.
For researchers employed at universities and public research institutions the registration fee is 150 EURO. This covers hand-outs, coffee and social events.
For all other participants the registration fee is 700 EURO.

Deadline:
Applicants should submit a request for registration to be at the hands of the course secretariat no later than six weeks before course start (eight weeks for students applying for scholarships and asking for assistance in finding accommodation). Information on enrollment will be posted within a week after this date.

Housing:
Lodging (Wednesday, June 18, to Thursday, June 26) in a special Research School University Residence will be offered on a first come, first served basis, at a cost of
DKR 1200 (EURO 160) for 8 nights.
Accomodation in hotels is also possible and should be arranged by the participants themselves, see the Wonderful Copenhagen site.

Scholarships:
For Ph.D.-students enrolled at non-Danish universities and research institutions, we can offer a limited number of scholarships in order to facilitate participation. A scholarship is intended for partial covering of extra living costs in connection with the course participation and covers lodging (see above) and a per diem (200 Euro in total for 8 days). Unfortunately NO subsidy of travel expences can be offered. Prospective students should in connection with the course registration send a brief application to the course secretariat indicating research interests and background. Enclose a CV and a short letter of recommendation from the Ph.D.-advisor at the home institution, and make sure the application is received by the course secretariat no later than eight weeks before course start (for candidates that require a visa, earlier response is strongly recommended).

For participants in the HMS2000 project should contact their country coordinators for information on possible financial support.

Brief report

The course was attended by 28 participants from 13 countries (Denmark, Sweden, Germany, Austria, UK, Belgium, France, Italy, Spain, Portugal, Switzerland, Japan and Korea); this included 9 Danes and 13 partcipants connected to the HMS2000 project. Industrial participation consisted of researchers from Volvo, Vestas Wind Systems, Grundfos, Toyota, and EADS. Also, a representative from Altair gave a presentation on industrial use of topology design.
