Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
A mesh is a representation of a larger geometric domain by smaller discrete cells. Meshes are commonly used to compute solutions of partial differential equations and render computer graphics, and to analyze geographical and cartographic data.
For example, a 2 mesh woven with a wire of 1.6mm wire diameter has an aperture of 11.1mm (see picture below of a 2 mesh with an intermediate crimp). The formula for calculating the aperture of a mesh, with a known mesh count and wire diameter, is as follows: = ()
Particle size is a notion introduced for ... In the selection of specific small-size particles is common the use of ISO 565 and ISO 3310-1 to the choice of mesh size.
For example, in order to obtain small invertebrates measuring 50 to 1500 μm, a net mesh size between 25 and 50 μm diameter should be selected, which is sufficient to effectively filter only the target organism. [3] However, in a eutrophic water condition, a plankton net with a mesh larger than 100 μm should be chosen to avoid clogging the ...

For example, the valve mapping in internal combustion engine is done very carefully so that the region of one type is mapped carefully with another type of region. There are regions where dense mesh is done deliberately to accommodate complex features. But this results in unnecessary grid resolution which leads to local variation of solution ...
