Real-time finite element modelling using CUDA

Here is a little movie showing real time simulation of non-linear elastic material properties using the Total Lagrangian Explicit Dynamic FEM. Three different sets of material parameters were used. Our implementation is done in CUDA. Thanks to Brian Bunch Christensen and Jens Rimestad for cooperation on the implementation.

The source code is under the LGPL licence and can be found here. Please acknowledge if you use it for your research. Thanks to Movania Muhammad Mobeen for tidying up the project so it should compile out of the box.

Dirk Fortmeier made this project work in linux using CMAKE. You can find the code for this at https://github.com/fortmeier/CUDA-FE-With-Haptics which also includes haptics interaction.

How we used the model in previous research can be read in the following paper:

Solid mesh registration for radiotherapy treatment planning.
K. Ø. Noe, T.S. Sørensen.
2010 International Symposium on Biomedical Simulation (ISBMS).
Lecture Notes in Computer Science, 2010; 5958: 59-70.
[abstract]

Some videos showing our use can be found here.

    I would be interested in the source code as well. Is it available?

    Best wishes,

      Hi. We are now considering to make the source code available. However, I think it needs a cleaning up first.

    It’d be wonderful if you could make the code available. I’d be interested in using it for my research.

    Thank your ! Perfect effect.
    Could you give some articles or explanations about the source code?
    Thanks.

    Thanks a lot, I compiled it under Linux using CMake and could provide a CMakeLists.txt if needed. Can you put the code under some kind of license (BSD,GPL etc.) so I know what I can do with it? Kind Regards!

    I integrated haptics into your code: http://youtu.be/wOYW3pSD7rE 🙂
