SIAM IMR24: Meshing Contest

The IMR Committee is pleased to announce that the Meshing Contest will again be part of the SIAM International Meshing Roundtable Workshop 2024, Mar. 5-8, 2023.


Participants can submit entries demonstrating the capabilities of their software in the following disciplines:

  • mesh generation
  • mesh post-processing

Surface (triangular, quad-dominant, quad, etc.) or volume (tetrahedral/hexahedral/hex-dominant/pyramid etc.) meshes or a combination of both are acceptable. The poster should include images showing the details of the mesh and the following information:

  • Participant(s) name(s)
  • Affiliation
  • Discipline: mesh generation or mesh post-processing or both
  • Meshing code/product used
  • Mesh size (number of nodes and elements of each type)
  • Meshing use (state the problem of physics/engineering the mesh is intended to be used for, specify analysis type)

As the IMR will be held in Baltimore the committee decided on a challenge with an appropriate local theme. The provided test cases geometries are:

  • A blue crab, a species native to Chesapeake Bay. This model was sourced from Smithsonian 3D Digitization and they have kindly given us permission to use it.
  • An Edgar Allan Poe bust, a famous poet who lived in the Baltimore in the mid 1800s. This model was sourced from @Scan The World hosted on and they have kindly given us permission to use it.

Either model can be meshed individually or both models can be meshed and combined in an inventive or impressive way. The goal is to produce a great picture demonstrating good meshing technique. A challenge of these models is representing sharp or small features in the mesh. The models contain only a single (or a few) surfaces, without sharp features represented by CAD curves and vertices. Remember, the winner of the Meshing Contest goes on the SIAM IMR25 t-shirt.


Presenters will give a one-minute presentation advertising their meshing contest entry using a single Powerpoint (.ppt) slide. Afterwards, attendees will be encouraged to visit the entries and discuss the details with the presenter. The attendees will be invited to vote on the best meshing contest entry from an aesthetic point of view: the winning entry will be featured on next year’s t-shirt. The logistics for printing and getting the poster to the venue are the responsibility of the author. Please do not laminate your poster.


Posters must be provided in an A0 .pdf format (841 mm x 1189 mm or 33.1” x 46.8”) with a minimum resolution of 300 dpi.

Email your note of commitment by the January 15, 2024 to Harry Fogg. Please upload a zipped (.7z format) copy of your poster pdf and ppt slide by February 12, 2024 on OpenConf.

To participate in the poster session, one must register and attend the conference.
