To generate a mesh from different, overlapping components to be in sync with each other for better connection.
This feature creates an HTML mesh quality report. The report can be generated for the current model or multiple models saved in a folder. The tool uses the standard HyperMesh criteria file as input. It summarizes the Quality Index (QI) calculations, along with information on the number of elements that fall into each QI range.
HyperMorph is an easy-to-use mesh manipulation tool within HyperMesh that allows users to quickly stretch any finite element mesh while keeping mesh distortion at a minimum.
The extend subpanel is used to create smoothly-meshed connections between different components that do not quite touch, but are meant to. Mesh can be imprinted such that both components are remeshed to match, or the source comp is remeshed to match the destination comp, or vice-versa. In addition, you can actually merge the elements of the source component into the destination component altogether.
Periodic Mesh Utility
The Periodic Mesh utility can be used to generate a grid containing rotational and/or translational symmetric boundaries, for example rotating machinery in use with CFD analysis. This utility provides the first two steps needed for the larger process of Periodic Mesh work flow.
In the first step, the mesh on the source geometry has to be generated using any of HyperMesh’s surface meshing algorithms – for example, 2D mesh with Boundary Layer.
In the second step of the Periodic Mesh utility, the mesh is mapped from the source geometry onto the target geometry. In addition to source and target geometry, detailed information about the transformation (rotational and/or translational) can be optionally entered.
To access this utility, from the menu bar click Mesh > Create > 2D Elements > Periodic Mesh.

Iso-surfaces of Q criterion are ones that out-line flow
regions with local rotation, indicating a turbulent eddy.
“Q” is a mathematical quantity commonly used to illustrate
turbulent vortices in
a flow field.
To bring costs down, wind-energy firms are recognizing the design benefits of numerical simulation. Transitioning to a simulation-based design process lets OEMs optimize performance and increase a turbine’s power output.
A valuable tool in this process is Computational Fluid Dynamics (CFD) software. It has traditionally played a role in the design of rotorcraft, fixed-wing aircraft, and even wind-turbine blades. Previous limitations in computing power kept most simulations focused on small portions of a design with a limited inclusion of physical phenomena. Perhaps the most accepted use of CFD in the industry is for analysis of 2D airfoils. Although an important application, recent advances in computing power and software provide greater capabilities for wind-turbine designers.
