Cells across the trailing edge (TE) should vary by mesh resolution.

Spanwise spacing at the root and tips should be 0.1 percent of the semi-span.

The chordwise spacing at the leading and trailing edges should be 0.1 percent of the local device chord.

Surface cell sizes near the nose and tail should be 1.0 percent CREF.

The farfield boundary should be 100 reference chords (CREF) distant.

Some of the meshing guidelines provided by HLPW are as follows.

Develop a thorough understanding of how the HLPW gridding e guidelines and the meshing techniques affected the ability and level of effort required to generate a mesh for GMGW.

meshes of coarse, medium, fine, and extra-fine resolution) that would allow for a grid convergence study by the HLPW. In this endeavor, the authors aspired to create high-quality meshes for two distinct purposes:

Note that, for the purposes of HLPW, the flap and slat are not attached to the wing and fuselage, and for the purposes of CFD simulation will be assumed to be “flying in formation” with the aircraft.įigure 3: The HL-CRM geometry (viewed from below) is shaded to represent the topology of the geometry model before quilting (left) and after quilting (right). The design was further modified for the specific purposes of HLPW, resulting in the geometry shown in Figure 1. The HL-CRM’s design was based on a high lift configuration that has been used in numerous experimental and numerical simulations. Therefore, since so much of the meshing process centers on the hybrid mesh, it will be emphasized in this article.

The high-order meshes were generated by curving the linear unstructured and hybrid meshes.

The hybrid overset mesh extracted the near-body cells from the hybrid mesh and added refinement blocks to fill the farfield.

The hybrid mesh was created by combining the unstructured mesh’s near-wall tetrahedra into prisms.

Volume mesh generation using T-Rex (anisotropic tetrahedral extrusion) was the same for all mesh types but subject to different postprocessing.

High-order meshes varied only in the amount of resolution, producing mesh families consisting of medium, coarse, tiny, and extra tiny levels.

Surface meshes and/or methods were identical for all meshes.

Geometry preparation was identical for all meshes.

The approach used to generate this family of meshes was: For the purposes of this article, unstructured will refer to an all-tetrahedra mesh, hybrid will refer to a prism-tetrahedra mesh, hybrid overset will refer to an overset mesh with near-body prism-tetrahedra and off-body Cartesian, and high-order will refer to a hybrid mesh elevated to a non-linear polynomial degree. Many of the methods and meshes are shared between the mesh types.

Both workshops will use the HL-CRM as a benchmark case for their respective goals. The goal of the Geometry and Mesh Generation Workshop (GMGW) is to assess the current state-of-the-art in geometry preparation and mesh generation for aircraft and spacecraft of interest to AIAA constituents. The goal of the High Lift Prediction Workshop (HLPW) is to assess the current capabilities of computational fluid dynamics (CFD) to numerically predict the high lift flow physics of a swept, medium-to-high-aspect ratio wing aircraft in a landing/take-off configuration. We generated several type of meshes (unstructured, hybrid, hybrid overset, and high order) for the NASA High Lift Common Research Model that are described here. Tecplot 360 interfaces with CFD solvers and analysis tools that export in Tecplot readable format.Pointwise is supporting two AIAA workshops (the 3rd High Lift Prediction and the 1st Geometry and Mesh Generation Workshop) to be held prior to AIAA Aviation in June 2017. SZL file format loads data faster because only the data needed for your plot is loaded at a given time. The Overset Cylinder uses Tecplot’s proprietary data format we call Subzone Load on Demand or SZL (pronounced “sizzle”). Navigate to the FlowOverCylinder folder in the bundle you downloaded.Choose the Tecplot Subzone Data Loader (*.szplt).Run Tecplot 360 and choose Load Data… from the File menu or use the Open File icon.The 2.4 MB Bundle file contains data used in many of our video tutorials and contains our Tecplot 360 Getting Started Guide.
