Pointwise's Quality Meshes Lead to Accurate CFD

Mesh quality is where the CFD analyst has the largest impact on solution quality - after all, the numerical algorithms and physical models are dictated by choice of the solver. A high quality mesh increases the accuracy of the CFD solution and improves convergence relative to a poor quality mesh. Therefore, it's important for a mesher to provide tools for obtaining and improving a mesh. Some meshing software uses hundreds of unnecessary blocks as a crutch to obtain a decent mesh. Pointwise's mesh methods, on the other hand, have been honed through years of application on analyses for which accuracy, and hence mesh quality, are critical.

Mesh quality tools in Pointwise keep you in control of mesh metrics relative to your acceptance criteria. Metrics can be examined graphically in great detail down to the cell-to-cell level. Cutting planes can be used to dissect the mesh to see the interior, graphical tools can be used to zoom in on the cells with the minimum and maximum metric values, and simply pointing at a cell will display it's metric value.

Global or local, finely detailed or macro-level, Pointwise's mesh examination tools help you achieve the desired mesh quality.

Monitor Quality Proactively Using Rules

Rules can be applied to proactively monitor the mesh quality. You define the acceptable values of any metric function (for example, minimum included angle must be greater than 5 degrees). Then as you're creating the mesh, pressing one button at the top level of the interface will immediately display all grids that violate the rule.
