The ANSYS central simulation environment

ANSYS Workbench is the central simulation environment for ANSYS that simplifies the entry of calculation tasks. Functions from ANSYS Classic can also be used in Workbench by using commands in APDL. Scripts let you automate and control ANSYS Workbench.

ANSYS Workbench impresses primarily with great efficiency in daily use, a standardized user interface, comprehensive networking technology, direct connection of all common CAD systems and a wide range of physical disciplines.

Uniform user interface for all operations

With ANSYS, you can perform all the steps of the simulation in a uniform user interface: From the production and treatment of geometry through networking and the definition of boundary conditions to evaluation. The advantage is that you use a parametric integrated system. You can transmit changes in subsystems by pressing a button on all of the relevant parts of the analysis – without manual effort. Variant studies are particularly quick and easy to perform in this way.

Direct connection to all common CAD systems

By direct connection of ANSYS Workbench to your CAD system, you can not only transfer geometry seamlessly, but use an active, intelligent link from the CAD model to the simulation software. The ANSYS simulation can automatically inherit changes of the CAD system, whereas all relevant definitions are retained in ANSYS. So you can evaluate design changes directly and perform variant studies systematically e.g. to target design optimization.

Comprehensive meshing technology

The comprehensive meshing technology of ANSYS is one of the most powerful in the market: The result of over 40 years of development and strategic acquisitions (ICEM CFD, CFX, FLUENT, Ansoft). ANSYS provides tailor-made methods for optimal, task-specific mesh creation. Manual and automatic meshing algorithms, intelligent refinement mechanisms, sophisticated mesh topologies and proven mesh patterns make working safely and quickly – for beginners as well as advanced users.

Geometry preparation suitable for simulation

The given geometry of CAD systems is suitable for matters of design, however it does not comply with all requirements needed for simulation. For example, flow analysis requires the fluid volume instead of the modelled solid object. Similarly, electromagnetic field computations require the air or vacuum volumes. Moreover, the geometrically modeled degree of detail is not sufficient for the simulation. Oftentimes unnecessary details are retained, like material descriptions and logos, and sometimes critical details like radii or purchased parts are omitted.


In some cases, such as for concept or feasibility studies in the early phases of product development, there is no geometry available in the CAD system and it must be generated from scratch.


In both application scenarios, the ANSYS product portfolio provides two tools, namely ANSYS DesignModeler and ANSYS Direct Modeler (ANSYS SCDM), that cover complementary strengths and application scenarios.

ANSYS DesignModeler

For history-based, parametric geometric modeling based on sketches, 3D, and Boolean operations. The complete mapping of geometric modeling with all processing steps in one tree provides rule-based dependencies and with it the "intelligence" of design elements. The reproducibility of the modeling and associative connection to many CAD systems provides automated geometry creation and variation processing. ANSYS DesignModeler shows its strengths when many changes are made in CAD or optimizations are made that also involve the geometry in the CAD system.

ANSYS SpaceClaim Direct Modeler

For fast modeling, modifying, or simplifying geometry. Instead of defining rules for creating or changing geometry, the geometry itself is manipulated with direct modelling. By moving surfaces, for example, the radius for a fillet or the width of a reinforcing rib can be changed regardless of the development history of the geometry, even with imported third-party data. The local changes defined in this manner can be given parameters in order to automatically change sections of the structure for variation studies. High-performance repair and smoothing functions are available for processing facetted geometry data (3D scan data, simulation results).

Enormous efficiency in daily use

The efficiency of ANSYS is mainly due to the high efficiency of the solver and to the functional practicality. The solvers used make it possible to simulate large assemblies, diverse details and very demanding physical effects. Automation functions that can be activated selectively, allow comfortable working by relieving the user, without patronizing him. One example is the automatic generation of connections, meshes and calculation reports, which you can customize by manual adjustments as needed to specific requirements.

Wide range of physical disciplines

With a variety of specialized solvers ANSYS covers a wide range of physical disciplines:

• Fluid Mechanics
• Structural Mechanics
• Electromagnetics
• Multiphysics and system simulation
• Temperature fields

The spectrum and the potential of ANSYS can even be expanded through the integration of existing complementary solutions developed by third parties or by CADFEM (CADFEM ANSYS Extensions) to implement specific functionalities. In addition, ANSYS is an open system that can be customized by the users to their own needs. As ANSYS Certified Channel Partner, CADFEM also offers seminars and services in the field of process automation and customization.
