Rapid B-rep model preprocessing for immersogeometric analysis using analytic surfaces
Computational fluid dynamics (CFD) simulations of flow over complex objects have been performed traditionally using fluid-domain meshes that conform to the shape of the object. However, creating shape conforming meshes for complicated geometries like automobiles require extensive geometry preprocessing. This process is usually tedious and requires modifying the geometry, including specialized o...
متن کاملShape Analysis of B - Rep CAD Models to Extract Partial and Global Symmetries
Symmetry properties of objects described as B-Rep CAD models are analyzed locally as wellas globally through an approach of type divide-and-conquer. The boundary of the object isdefined using canonical surfaces frequently used when shaping mechanical components. Then,the first phase consists in generating maximal faces and edges that are independent from theobject modelling proc...
متن کاملWatertight Tessellation of B-rep NURBS CAD-Models Using Connectivity Information
This paper presents a fast method to avoid cracks between two adjacent NURBS-surfaces which are part of a boundary-represented 3D-object during the tessellation process. The surfaces are first divided into almost flat regions, then trimmings curves are split at the patch borders and finally intersection points are transferred to the opposite surface by using a priori connectivity information. T...
متن کاملImmersogeometric cardiovascular fluid-structure interaction analysis with divergence-conforming B-splines.
This paper uses a divergence-conforming B-spline fluid discretization to address the long-standing issue of poor mass conservation in immersed methods for computational fluid-structure interaction (FSI) that represent the influence of the structure as a forcing term in the fluid subproblem. We focus, in particular, on the immersogeometric method developed in our earlier work, analyze its conver...
متن کاملA framework for designing patient-specific bioprosthetic heart valves using immersogeometric fluid-structure interaction analysis.
Numerous studies have suggested that medical image derived computational mechanics models could be developed to reduce mortality and morbidity due to cardiovascular diseases by allowing for patient-specific surgical planning and customized medical device design. In this work, we present a novel framework for designing prosthetic heart valves using a parametric design platform and immersogeometr...
