The optimal starting point for creating a shell mesh for a part is to have geometry surfaces defining the part. The
most efficient method for creating a mesh representing the part includes using the Automesh panel and creating a mesh
directly on the part’s surfaces.
Surfaceless meshing is defined as the creation of mesh using points, lines, and nodes rather than surfaces. Some parts
may have missing surfaces and some parts may not have any surfaces at all and are instead defined by line data. Either
way, a mesh still must be created. HyperMesh has a number of panels that you can use to create a mesh based on geometry rather than surfaces.
Chordal deviation is a meshing algorithm that allows HyperMesh to automatically vary node densities and biasing along curved surface edges to gain a more accurate representation
of the surface being meshed.
BatchMesher is a tool that can perform geometry cleanup and automeshing (in batch mode) for given CAD files. BatchMesher performs a variety of geometry cleanup operations to improve the quality of the mesh created for the selected
element size and type. Cleanup operations include: equivalencing of "red" free edges, fixing small surfaces (relative
to the element size), and detecting features.
You can use the Shrink Wrap tool to generate an enclosed volume or solid mesh. This tool is typically used to approximate
and simplify an existing model.
HyperMesh provides two methods for generating a tetrahedral element mesh. The volume tetra mesher works directly with surface
or solid geometry to automatically generate a tetrahedral mesh without further interaction from you. Even
with complex geometry, this method can often generate a high quality tetra mesh quickly and easily.
For some analyses, it is desirable to use a mesh of hexahedral and pentahedral elements. This is especially true for
parts which have a large thickness compared to the element size being used, or for parts that have many features and/or
changes in thickness. Castings or forgings are good examples.
Solids are geometric entities that define a three-dimensional volume. The use of solid geometry is helpful when dividing
a part into multiple volumes. For example, divide a part into simple, mappable regions to hex mesh the part. Use the
Solid Map panel to create a mesh of solid elements in a solid geometric volume.
The Process Manager contains a step-by-step checklist of procedures that allow you to quickly organize and tetramesh
a geometric model. Each step is formatted in a hierarchical list that provides the order in which the process must
be performed. Specialized tools are also provided at each step to simplify the process. You can perform these steps
manually, but it is generally faster to perform them in the Tetramesh Process Manager.
Learn how to perform a DOE study using HyperStudy and the HyperStudy Job Launcher within HyperMesh. HyperMorph is used to parameterize the shape of the design.
Browsers supply a great deal of view-related functionality by listing the parts of a model in a tabular and/or tree-based
format, and providing controls inside the table that allow you to alter the display of model parts.
Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing
process using the Verification and Comparison tools.
