This research deals with two important problems in computational                engineering; error estimation and adaptive grid control. In particular,         the following areas will be considered:                                                                                                                         Evaluate alternate hybrid/mixed finite element formulations for the             linear biphasic theory.                                                                                                                                         Develop a two-dimensional triangular axisymmetric elements for the              linear biphasic weighted residual/penalty finite element analysis and           integrate this using the  finite quadtree automatic mesh generator              with remeshing capabilities.                                                    Develop adaptive analysis capability for two-dimensional problems               based on initial error estimators and error indicators.                                                                                                         Evaluate the solution algorithm for selected axisymmetric problems              and perform error analysis for the linear biphasic theory.                                                                                                      Develop a nonlinear biphasic analysis including strain dependent                permeability for axisymmetric problems.                                                                                                                         The soft hydrated tissue is the biphasic medium where the algorithm             will be tested.  This type of modelling will allow researchers to               investigate physiologically realistic loading and geometries in                 biomechanics of joints.  One of the principal investigators has been            collaborating with the Orthopedic Research Laboratory at Columbia               University to delineate the lubrication mechanisms in synovial joints,          this computational effort will complement very nicely the                       biomechanics research.
