IUTAM Symposia assemble active scientists within a well-defined field for the development of science in that field. IUTAM Summer Schools are organized mainly for young scientists and have an educational focus. Those wishing to participate in an IUTAM symposium should contact the Chairperson of the Scientific Committee of the Symposium in advance of the meeting.

Every two years a call is launched on the IUTAM website for submitting proposals for IUTAM Symposia and Summer Schools in both fluid and solid mechanics, including dynamics. Prospective organisers submit a proposal, and can request up to $5000 from IUTAM toward the organisation of the Symposium, especially to support younger researchers. Publication of proceedings is optional.
