Ansys Meshing

The goal of meshing in Ansys Workbench is to provide robust, easy to use meshing tools that will simplify the mesh generation process. The Ansys Meshing tools have the benefit of being highly automated along with having a moderate to high degree of user control.

The Ansys Mechanical application is recommended if you plan to stay within the Ansys Mechanical application to continue your work (preparing and solving a simulation). Also, if you are planning to perform a Fluid-Structure Interaction problem, and desire to use a single project to manage your Ansys Workbench data, you can use the Mechanical application to perform your fluid meshing. This is most conveniently done in a separate model branch from the structural meshing and structural simulation.

On the other hand, the Ansys Meshing application is recommended if you plan to use the mesh to perform physics simulations in Ansys CFX or Ansys Fluent. If you wish to use a mesh created in the Meshing application for a solver supported in the Mechanical application, you can replace the Mesh system with a Mechanical Model system.

Structures   Ansys Structural Analysis

Ansys Structural analysis is probably the most common application of the finite element method. The term structural (or structure) implies not only civil engineering structures such as bridges and buildings, but also naval, aeronautical, and mechanical structures such as ship hulls, aircraft bodies, and machine housings, as well as mechanical components such as pistons, machine parts, and tools. It has the ability to perform the following types of structural analyses:
  • Static Analysis– Used to determine displacements, stresses, etc. under static loading conditions. Both linear and nonlinear static analyses. Nonlinearities can include plasticity, stress stiffening, large deflection, large strain, hyperelasticity, contact surfaces, and creep.
  • Modal Analysis– Used to calculate the natural frequencies and mode shapes of a structure. Several mode-extraction methods are available.
  • Harmonic Analysis– Used to determine the response of a structure to harmonically time-varying loads.
  • Transient Dynamic Analysis– Used to determine the response of a structure to arbitrarily time-varying loads. All nonlinearities mentioned under Static Analysis above are allowed.
  • Spectrum Analysis– An extension of the modal analysis, used to calculate stresses and strains due to a response spectrum or a PSD input (random vibrations).
  • Buckling Analysis– Used to calculate the buckling loads and determine the buckling mode shape. Both linear (eigenvalue) buckling and nonlinear buckling analyses are possible.
Several special-purpose structural analysis capabilities are also available:
  • Fracture mechanics
  • Composites
  • Beam analyses and cross sections   Ansys Mechanical

Ansys Mechanical is a Workbench application that can perform a variety of engineering simulations, including stress, thermal, vibration, thermo-electric, and magnetostatic simulations. A typical simulation consists of setting up the model and the loads applied to it, solving for the model’s response to the loads, then examining the details of the response with a variety of tools. Ansys Mechanical has “objects” arranged in a tree structure that guide you through the different steps of a simulation. By expanding the objects, you expose the details associated with the object, and you can use the corresponding tools and specification tables to perform that part of the simulation. Objects are used, for example, to define environmental conditions such as contact surfaces and loadings, and to define the types of results you want to have available for review.   Ansys LS-DYNA

Ansys LS-DYNA is a general-purpose finite element program capable of simulating complex real-world problems. It is used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries. The LS-DYNA solver is optimized for shared and distributed memory Unix, Linux, and Windows based platforms, and it is fully QA’d by Ansys. The code’s origins lie in highly nonlinear, transient dynamic finite element analysis using explicit time integration. “Nonlinear” means at least one (and sometimes all) of the following complications:
  • Changing boundary conditions (such as contact between parts that changes over time)
  • Large deformations (for example the crumpling of sheet metal parts)
  • Nonlinear materials that do not exhibit idealy elastic behavior (for example thermoplastic polymers)
“Transient dynamic” means analyzing high speed, short duration events where inertial forces are important. Typical uses include:
  • Automotive crash (deformation of chassis, airbag inflation, seatbelt tensioning)
  • Explosions (underwater Naval mine, shaped charges)
  • Manufacturing (sheet metal stamping)
LS-DYNA’s potential applications are numerous and can be tailored to many fields. In a given simulation, any of LS-DYNA’s many features can be combined to model a wide range of physical events. LS-DYNA is one of the most flexible finite element analysis software packages available.   Ansys Composite PrepPost (ACP)
