An FE model in prolate spheroidal coordinates has been fitted to the average geometry of 4 dog hearts measured with 3D ultrasound. The model is inflated using a set of "true" parameters to obtain a set of synthetic strain measurements. A Gauss-Newton approach is then used to try to estimate these "unknown" (true) parameters.

Run the example using "perl estimate.pl". See comments in estimate.pl for more details.Note, it uses the PDL perl module.

These files were used for the paper "Development of an in vivo method for determening material properties of passive myocardium" J. of Biomech. May 2004. Note that this is not a cmiss test example but rather a storage of the files for future reference and the files may need updating to be able to run them in the future.
