This paper develops a size-adaptive hybrid meshing scheme for Chemical Species Tomography (CST) that is driven by the customized spatial resolution of sensing region. Traditionally, entire region in CST uniformly discretized with empirically determined density meshes. Such discretization results a) waste computational efforts on less spatially resolved location; and b) much severer rank deficie...

A new mesh generation algorithm called ‘LayTracks’, to automatically generate an all quad mesh that is adapted to the variation of geometric feature size in the domain is described. LayTracks combines the merits of two popular direct techniques for quadrilateral mesh generation—quad meshing by decomposition and advancing front quad meshing. While the MAT has been used for the domain decompositi...

We present results from a three-dimensional device simulator, using adaptive meshing and solving the drift-diffusion equations. The adaption algorithm and the criteria used for adap-tion are discussed. Three devices of industrial interest are presented: a bipolar transistor, a 1.25/zm n-MOS device and a CCD, illustrating the range of devices which may be successfully simulated.

An approach hybrid optical-computational criterion to generate an adaptive refinement mesh to be used in mechanical structure analysis with Finite Element Method (FEM) is proposed. The numerical error to determine the refinement zones in adaptive meshing is substituted for an experimental weight function. Experimental optical phase map is used to define this weight function. This criterion perm...

It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...

Generating accurate volume meshes from segmented image volumes is important in certain medical applications. One application is finite element analysis (FEA) for orthopaedic pre-operative planning. The resulting FEA models can be used in patient-specific, bio-mechanical simulations and implants positioning. Currently available software packages for volume meshing of segmented data can generate ...

Meshing is a critical, but user-intensive process necessary for stable and accurate simulations in computational fluid dynamics (CFD). Mesh generation often bottleneck CFD pipelines. Adaptive meshing techniques allow the mesh to be updated automatically produce an solution problem at hand. Existing classical adaptive require either additional functionality out of solvers, many training simulati...
