ANSYS Meshing Solutions
Comprehensive Multiphysics Meshing Tools
Meshing is an integral part of the computer-aided engineering simulation process. The mesh influences the accuracy, convergence and speed
of the solution. Furthermore, the time it takes to create and mesh a
model is often a significant portion of the time it takes to get results
from a CAE solution. Therefore, the better and more automated the
meshing tools, the better the solution.
From easy, automatic meshing to a highly crafted mesh, ANSYS provides
the ultimate solution. Powerful automation capabilities ease the initial
meshing of a new geometry by keying off physics preferences and using
smart defaults so a mesh can be obtained upon first try. Additionally, a
user can update immediately to a parameter change, making the handoff from CAD to CAE seamless and aiding in upfront design.
Once the best design is found, meshing technologies from ANSYS
provide the flexibility to produce meshes that range in complexity from
pure hex to highly detailed hybrid; a user can put the right mesh in the
right place and ensure that a simulation will accurately validate the
physical model.
ANSYS has a range of meshing tools that cater to nearly all physics.
While the meshing technologies were developed to meet needs in a
specific area — solid, fluid, electromagnetic, shell, 2-D or beam models
— access to these technologies is available across all physics.
Structures Modeling
For solid models, meshing technologies from ANSYS provide robust,
well-shaped quadratic tetrahedral meshing on even the most complicated geometries. With automatic contact detection and setup, a user
requires little training to perform sophisticated analysis. In addition,
users can generate pure hex meshes using one of several mesh methods,
depending on the type of model and whether the user wants a pure hex
or hex-dominant mesh.
