• ANSYS Workbench comprises the following modules:
– Simulation for performing structural and thermal analyses using the ANSYS solver gnModele
– Meshing for generating a mesh for Mechanical, Electromagnetic or CFD application
– DesignModeler for creating and modifying CAD geometry to prepare the solid model for use in Simulation or Meshing er
– DesignXplorer and DesignXplorer VT for investigating the effect of variations input to the response of the system
– FE Modeler for 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

• There are various types of files used by Workbench, each differentiated by the file extension: gnM

– .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
– cmdb: Meshing database containing the mesh settings and mesh information er.cmdb: Meshing database, containing the mesh settings and mesh information
– .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
– eddb: Engineering Data database file Containing all material convection load history and other– .eddb: Engineering Data database file. Containing all material, convection, load history and other pertinent project information. This file is saved automatically whenever .wbdb file is saved. (Simulation and DX databases utilize engineering data)

• 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 gnM

associated together.
• Whenever a DesignModeler database (.agdb) or a Meshing database (*.cmdb) is created, there will be an associated Workbench database (.wbdb) er( ) , ( )generated as well.
• Saving the Workbench database is not required, but it is helpful in keeping track of various analyses especially if multiple geometries are analyzed Alsotrack of various analyses, especially if multiple geometries are analyzed. Also .eddb and .param files will be saved automatically while saving Workbench databases.
