A novel approach to generating watertight, manifold boundary representations from noisy binary image masks of MRI or CT scans is presented. The method samples an input segmented image and locally approximates the material boundary. Geometric error me

One of the most time-consuming tasks in performing any discrete analysis the construction of a suitable mesh to represent the computational domain. Mesh generation today remains one of the pacing items in computational mechanics and consumes too many

A configuration of prismatic elements in boundary layers created by marching a surface triangulation on viscous walls along certain directions is a typical mesh for viscous-flow simulations. The qu...

Hexahedral (hex) meshes can be generated for CAD models of complex thin-walled components by isolating thin-sheet and long-slender regions, quad meshing one of the bounding faces, and sweeping the quad mesh through the volume to create hex elements.

Mesh quality strongly affects the solution accuracy in electromagnetic finite-element analysis. Hence, the realization of adequate mesh generation becomes a very important task. Several adaptive meshing methods for automatic adjustments of the mesh d

A new paradigm is presented for finite element analysis in CAD environments.The focus is, firstly, on operating directly with clean-up on the CAD geometry.The focus is, secondly, on establishing efficiently a finite element mesh.Overlapping finite el

International audience; Many practical problems are of multiscale nature. This issue appears when relatively small regions inside the computational domain have a large impact on the overall behavior of the structure. This requires using small mesh si
