[Dune] Soft Tissue Deformation Models with Dune

[Dedner, Andreas]

Hi,

thats really a rather difficult question to answer - even
if I did know exactly what your model is. But without exactly the model and its size...

I think the Galleries on the dune homepage give you a good
idea of some of the things that have been done with dune -
or at least of what is directly available.

If dune is efficient enough - depends on the size of your
problem  and on how complex your model is to be.
If your problem involves
some type of computation using unstructured grids then dune should be similar in performance to other packages (as far as
I know). If you can use Cartesian grids and finite-difference methods then probably dune is not the efficient choice.

That's the best information I can give. There are some dune school which you might want to attend there you can discuss your problem directly with people developing dune. There is a scbool in Heidelberg, Germany (quite sone), there is one in Warwick, UK in July and in Stuttgart sometime later this year.

Best
Andreas

Subject: [Dune] Soft Tissue Deformation Models with Dune

To the Dune community,

I am participating in a project involving tracking and estimating the motions and deformations of the brain in an open-skull surgery.  Essentially, we have a stereo video stream, in which we detect and track feature points, and estimate their 3D locations.  These locations would be used first to define a rigid motion, and their residuals will define boundary conditions for the deformation.

I would like to know if Dune contains the functionality needed for such an objective, and if there is a performance estimation of the computation on reasonable PC workstation (possibly multi-processor).  Of course, there is a variety of ways to define the model type and solution method.  The simplest one we had in mind was a mesh of springs.  But we can use more sophisticated models if they are useful.

I will be happy to add more information on the problem if it is requested.

Sincerely,
