Unfortunately, many finite element embedded boundary methods (cutFEM, Finite Cell Method, etc. ) are also difficult to implement due to: (a) the need to perform complex cell cutting operations at boundaries, (b) the necessity of specialized quadrature formulas, and (c) the consequences that these operations may have on the overall conditioning\/stability of the ensuing algebraic problems.<\/p>\n<p style=\"font-size: 1.2em\">We present a new, stable, and simple embedded boundary method, named \u00abShifted Boundary Method\u00bb (SBM), which eliminates the need to perform cell cutting. Boundary conditions are imposed on a surrogate discrete boundary, lying on the interior of the true boundary interface. We then construct appropriate field extension operators by way of Taylor expansions, with the purpose of preserving accuracy when imposing the boundary conditions. We demonstrate the SBM in applications involving solid and fracture mechanics; thermomechanics; CFD and porous media flow problems.<\/p>\n<p style=\"font-size: 1.2em\">In particular this talk will present recently published and unpublished work &nbsp;on penalty-free formulations for boundary value problems, simplified data structures\/ variational formulations for fracture mechanics, extension operators alternative to Taylor expansions for the imposition of boundary conditions. Part of this work has been accomplished in a number of collaborations with CIMNE and UPC.<\/p>\n<h5 class=\"cimne blue-background\" style=\"padding-left: 15px;float: none\">SPEAKER CV<\/h5>\n<p style=\"font-size: 1.2em\"><strong><img decoding=\"async\" src=\"https:\/\/cimne.com\/cvdata\/cntr2\/spc2\/dtos\/mdia\/\/guglielmo-scovazzi.jpg\" alt=\"Guglielmo Scovazzi\" style=\"float: left;padding-right: 15px;padding-top: 5px\" width=\"165\" height=\"\" \/>Guglielmo Scovazzi<\/strong> is a Professor of Civil &amp; Environmental Engineering and Mechanical Engineering &amp; Materials Science at Duke University.
