More Control and Better Meshes in Pointwise Version 18.5

Automation in CFD mesh generation is of limited use if the resulting mesh isn’t suitable for the intended simulation. One of the many aspects of suitability is mesh quality, the distortion and skewness of the mesh elements relative to a perfect shape.

Cadence Pointwise Meshing Version 18.5 addresses the issue of mesh suitability with the addition of two new features. First, weighted condition number smoothing is now available as a post-processing step for the T-Rex hybrid mesher. WCN smoothing can significantly improve the quality of the mesh in the transition region between the anisotropic cells resolving the boundary layer and the isotropic cells away from the walls. Second, a new meshing technique called Thin Surface Interpolation is now available to automatically mesh wing trailing edges and similar thin regions with a quad-dominant unstructured mesh that closely mimics a structured quad grid.

Of course, working with the geometry model being meshed continues to require attention. In Pointwise V18.5 you’ll find new tools for creating surfaces that are tangent continuous with their neighbors and curves that can be tangent or orthogonal to their neighbors.

Here are some videos describing how you exploit these new capabilities for your CFD process.

Thin Surface Interpolation – In the past, many trailing edge domains started out life as structured domains and were quickly diagonalized, resulting in highly structured looking unstructured domains. To help save our users time, we now have an initialization routine available to create this same effect in one single step. This video demonstrates how to make that happen with Thin Surface Interpolation. https://youtu.be/JtDR9lp4w3Y

Volume Mesh Anisotropic-Isotropic Smoothing – This video introduces the new smoothing feature available on the solver panel for unstructured blocks. It works on both isotropic and T-Rex (anisotropic) cells. We'll discuss the new parameters such as the Cost Angle Threshold and the special ability that gets unlocked when you set it to zero. https://youtu.be/LH4zFsgsEM8 

Curve Slope Continuity – This video demonstrates a new drawing aid in Pointwise that helps the user create connector and curve segments that are either tangent or perpendicular to existing segments. This drawing aid appears temporarily, like a catalyst, during the entity creation process. https://youtu.be/e-WIjbK9igo

Coons Surface Tangency – In this video, we demonstrate a new feature available in the coons patch interface. Users can now use the tangency of the surrounding edges to produce a seamless and continuous patch over an existing hole or void. https://youtu.be/NnHu7-IZFoQ
