ANSYS Workbench Overview
Desi
ANSYS Workbench comprises the following modules:
Simulation for performing structural and thermal analyses using the ANSYS solver nModel
Meshing for generating a mesh for Mechanical, Electromagnetic or CFD application
DesignModelerfor creating and modifying CAD geometry to prepare the solid model for use
in Simulation or Meshingr
DesignXplorerand DesignXplorer VT for investigating the effect of variations input to the
response of the system
FE Modelerfor translating a Nastran mesh for use in ANSYS
Advanced CFD for performing CFD analyses using the CFX Solver
Advanced Meshing for generating complex CFD grids and sophisticated structural FEA
meshes using full ICEM CFD version
AUTODYN for modeling nonlinear dynamics of solids, fluids, gas and their interaction

Workbench Databases
Desi
There are various types of files used by Workbench, each differentiated by the file
extension:nModel
.wbdb: Workbench Project database, which keeps track of all of the different types of Workbench
databases in a Project
.agdb: DesignModeler database, containing geometry data for use with Simulation or CFX-Mesh
r. , .dxdb: DesignXplorer/DesignXplorer VT database, which investigate relationships between input
and output parameters
.dsdb: Simulation database, which has all the information necessary to perform a structural or
thermal analysis in Simulation
.fedb: FE Modeler database, which has mesh information from a Nastran or Simulation model,
used to convert to ANSYS
. . , ,
pertinent project information. This file is saved automatically whenever .wbdb file is saved.
(Simulation and DX databases utilize engineering data)

Workbench Databases
Desi
The Workbench database is simply a directory of a Project. A Project can
be thought of as a collection of different CAD or Workbench files, which are nModel
associated together.
Whenever a DesignModeler database (.agdb) or a Meshing database
*.cmdb is created there will be an associated Workbench database .wbdb rgenerated as well.
Saving the Workbench database is not required, but it is helpful in keeping, .
.eddb and .param files will be saved automatically while saving Workbench
databases.
