The meshing capabilities are available within the following Ansys Workbench applications. Access to a particular application is determined by your license level.
The Ansys Mechanical application - 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.
The Ansys Meshing application - 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. See Replacing a Mesh System with a Mechanical Model System.
Note: In the 2024 R2 release, Ansys Autodyn runs inside the Mechanical application. The recommendation is to use an Explicit Dynamics analysis system, in which meshing comes as part of that system. As an alternative, you can also use this system to prepare a model for the traditional Ansys Autodyn application (AUTODYN component system). For simple Ansys Autodyn models, you can use the meshing tools within the traditional Ansys Autodyn application (AUTODYN component system).
