Hyperbolic Extrusion Smoothing Parameters
 
03:00
In this video we demonstrate the hyperbolic extrusion smoothing parameters. When performing a normal hyperbolic extrusion the front may include concavities or other features that prevent layers from advancing. Often adjusting the smoothing parameters found in the Attributes tab can improve the result of the extrusion by preventing grid line crossing and numerical instabilities. There are four parameters that can be adjusted: Explicit, Implicit, Kinsey Barth, and Volume. The Explicit and Implicit parameters control smoothing in the transverse direction. The Kinsey Barth parameter helps prevent grid lines from crossing in the marching direction. And lastly, the Volume smoothing parameter determines how rapidly grid clustering along the extruding front will relax.

Structured Meshing Strategies for Wing Tips
 
03:00
In this video we compare two different structured meshing strategies for wing tip geometries. One of the strategies presented results in high included angles near the leading edge of the geometry that can approach 180 degrees as the mesh is refined. The preferred approach is an O-H topology that improves the overall grid quality, particularly near the leading edge of the wing tip.

Synchronize Connector Spacings
 
02:38
In this video we demonstrate how to sync connector spacings at nodes. When faced with high cell area ratios, the cause is often due to mismatched spacings at nodes. The solution is to use the same spacing value for all connectors that share a node, a process that has been automated by the new sync spacings command.

Structured Meshing Strategies for Circular Geometry
 
03:01
In this video we demonstrate three multi-block structured meshing strategies for circular geometry. The first is a traditional H-grid resulting in high included angles in the four corners of the topology. The second approach utilizes a pole, or singularity, to create a high quality structured domain consisting of quadrilateral elements at the core of the topology with collapsed edges. The third, and preferred, approach is known as an O-H-grid consisting of five domains resulting in a high quality structured mesh once elliptic smoothing has been applied.

Unstructured Domain Surface Shape
 
02:39
In this video we demonstrate the options for defining unstructured domain surface shape from the Grid, Solve panel. An unstructured domain's shape can either be constrained or free. Constrained means that the points will be associated with some underlying geometry, while free means that the interior points are initialized using only the bounding grid curves. This option can be changed from the Surface Shape frame within the Grid, Solve panel.

Assembling Quilts
 
01:53
In this video we demonstrate how to use the Create, Assemble, Quilts tool to assemble an array of quilts into a single quilt for meshing. A quilt is a watertight representation of the underlying trimmed surfaces. For meshing, a quilt is a logical meshing region. As you can see in this example, meshing a model consisting of four quilts results in four domains. However, when we assemble the four quilts into a single quilt and then mesh the model, only a single domain is created. This is a great way to reduce the complexity of the surface mesh topology prior to meshing.
