Buckling in Workbench Simulation [PDF]
  Sheldon Imaoka (ANSYS, Inc.)
  "Buckling may be a concern for some situations, where a user may need to modify the design to prevent buckling within a given load range. Conversely, failure analysis may need to be performed when a structure has collapsed.
ANSYS and Workbench Simulation have many tools to aid users in solving geometric instability problems, ranging from linear (eigenvalue) buckling to nonlinear, post-buckling analyses."

Meshing in Workbench [PDF]
  Sheldon Imaoka (ANSYS, Inc.)
  "Mechanical users have long enjoyed access to a variety of powerful meshing tools inside of ANSYS to generate high-quality shell, tetrahedral, and swept meshes. During the past several years, meshing in ANSYS Workbench Simulation has not only grown to encompass traditional meshing algorithms in ANSYS but has also developed many features requested by ANSYS users as well as integrated meshing technologies from ANSYS CFX and ANSYS ICEM CFD."

Spatially-Varying Pressure Loading in Workbench Simulation [ZIP]
  Sheldon Imaoka (ANSYS, Inc.)
  "Workbench Simulation 11.0 allows users not only to apply constant pressure loads or force vectors per unit area but also to utilize hydrostatic pressure loads and line pressure loads (force per unit length), and these can be defined as a function of time. Moreover, fluid pressures can be mapped from a steady-state or transient ANSYS CFX solution.
Despite these options, there may be situations where a user may want to import a predefined, spatially-varying pressure field from an external text file. This can be accomplished through the use of a “Commands” object and APDL tables, which this memo will introduce."

Understanding the Response Surface Method in DesignXplorer [PDF]
  Sheldon Imaoka (ANSYS, Inc.)
  "ANSYS DesignXplorer enables the user to perform optimization studies based on multiple objectives, to account for uncertainties in product design and use, and to determine how best to improve product reliability. These tasks are accomplished through the use of response surfaces, and this memo hopes to cover some of the basics of DesignXplorer operation."

Using CMS in Workbench Simulation [ZIP]
  Sheldon Imaoka (ANSYS, Inc.)
  "At Workbench 11.0, the ANSYS Rigid Dynamics add-on module enables users to model complex kinematic assemblies, whereby system-level performance as well as accurate force loading on components can be obtained.
Although the parts in the assembly may initially be considered rigid, an interesting, related method is the use of component mode synthesis (CMS) to account for the flexibility of parts. This memo will attempt to cover a way in which users can incorporate CMS in their multibody analyses in Workbench Simulation."

[For version 12.0, use supplied "cms_use_v12.mac" instead of "cms_use.mac" - courtesy of D. Creech.]

Using the Radiosity Solver in Workbench Simulation [PDF]
  Sheldon Imaoka (ANSYS, Inc.)
  Please note that in Workbench Mechanical 12.1, surface-to-surface radiation (using the Radiosity Solution Method) has been introduced in the GUI, so this memo is obsolete if you use version 12.1 and higher.
"Radiation can play an important role in heat transfer analyses. In Workbench Simulation 10.0, a “Radiation” load has been added to allow users to account for losses to the surroundings, although this does not include radiation exchange between surfaces.
For users wishing to utilize the ANSYS surface-to-surface radiation capabilities, this memo hopes to introduce an easy method to include these effects within Workbench Simulation via Named Selections and Command objects.
This type of methodology can be extended to include any other advanced solution feature of ANSYS which the user may wish to incorporate inside of Workbench Simulation."

Using the WB Simulation Remote Solution Manager [PDF]
  Sheldon Imaoka (ANSYS, Inc.)
  "Workbench Simulation has the ability to allow the user to solve multiple jobs locally or remotely. These capabilities are defined within the “Solution” branch of WB Simulation as well as in the WB Remote Solution Manager.
"This memo hopes to introduce this capability, especially with regards to solving multiple jobs locally on a Windows machine."

Workbench XML Material Format
  (ANSYS, Inc.)
  ANSYS Workbench Engineering Data module (e.g., Workbench Simulation, Workbench FE Modeler) can import/export material data as XML files. These XML files utilize the MatML format, and this zip file contains an example. This can be useful for users wishing to generate their own material libraries in XML format outside of Workbench Engineering Data.
