A flow solver based on a mixed mesh paradigm is developed for resolving flows in a high-order accurate manner. The proposed mesh topology involves unstructured tetrahedral/prismatic mesh in the near-body region and adaptive Cartesian-based unstructured mesh in the off-body region. The body-conforming near-body unstructured mesh offers a great flexibility in treating complex geometries, and also...

This paper proposes an algorithm for generating a mesh that is similar to a given reference mesh in particular features. In the design process, similar kinds of meshes are generated for the same shape or similar shapes repeatedly. Once a mesh having the desired features is obtained, our algorithm can generate the succeeding meshes efficiently by imitating a selected set of features of the refer...

In this paper, we introduce a new mesh filtering method: a mesh median filter. This is an application of the median filter to smoothen 3-D noisy shapes given by triangle meshes. An algorithm of the mesh median filter is realized by applying the median filter to face normals on triangle meshes and updating mesh vertex positions to make them fit to the filtered normals. As an advanced modificatio...

This paper presents a new method for surface mesh simplification. Given an initial surface mesh (denoted as reference mesh), the goal is to reduce the number of mesh elements while preserving the geometric approximation as well as the shape quality of the resulting mesh. Two tolerance areas with respect to the reference mesh have been introduced to preserve the geometry of the surface. The refe...

This paper describes a parallel procedure for anisotropic mesh adaptation with boundary layers for use in scalable CFD simulations. The parallel mesh adaptation algorithm operates with local mesh modification operations developed for both unstructured and boundary layer parts of the mesh. The adaptive approach maintains layered elements near the viscous walls and accounts for the mesh modificat...

By using lactose colored with erythrocin, we examined the effect of particle size on mixing degree during the preparation of triturations with a mortar and pestle. We used powders with different distributions of particle sizes, i.e., powder that passed through 32-mesh but was trapped on a 42-mesh sieve (32/42-mesh powder), powder that passed through a 42-mesh sieve but was trapped on a 60-mesh ...
