<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
<br>
thats really a rather difficult question to answer - even<br>
if I did know exactly what your model is. But without exactly the model and its size...<br>
<br>
I think the Galleries on the dune homepage give you a good<br>
idea of some of the things that have been done with dune -<br>
or at least of what is directly available.<br>
<br>
If dune is efficient enough - depends on the size of your<br>
problem and on how complex your model is to be. <br>
If your problem involves<br>
some type of computation using unstructured grids then dune should be similar in performance to other packages (as far as<br>
I know). If you can use Cartesian grids and finite-difference methods then probably dune is not the efficient choice.<br>
<br>
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.<br>
<br>
Best<br>
Andreas<br>

<div>To the Dune community,</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>I will be happy to add more information on the problem if it is requested.</div>
<div> </div>
<div>Sincerely,<br clear="all">
