Introduction

ANSYS EKM - Engineering Knowledge Manager What is ANSYS EKM?

Training Manual

ANSYS Engineering Knowledge Manager (EKM) is a web-based multi-user collaborative product that is aimed at meeting the simulation data and process management challenges faced by our customers. EKM is tightly integrated with other ANSYS simulation offerings and it can also be very easily integrated with other simulation codes including legacy and competitors software.

What is ANSYS EKM Desktop? ANSYS EKM Desktop is a single user, local environment version of EKM. It is available as part of ANSYS R12 release and it can be accessed via Workbench. EKM Desktop is focused at meeting the challenge of re-using existing simulations and thereby increasing simulation productivity and efficiency.

EKM Desktop can be started under the File menu in the Project window

B. ANSYS Workbench Overview What is ANSYS Workbench?

Training Manual

ANSYS Workbench provides powerful methods for interacting with the ANSYS family of solvers. This environment provides a unique integration with CAD systems, and your design process.

ANSYS Workbench is comprised of various applications (some examples): Mechanical for performing structural and thermal analyses using the ANSYS solver Meshing is also included within the Mechanical application

Fluid Flow (CFX) for performing CFD analyses using CFX Fluid Flow (FLUENT) for performing CFD analyses using FLUENT Geometry (DesignModeler) for creating and modifying CAD geometry to prepare the solid model for use in Mechanical. Engineering Data for defining material properties Meshing Application for generating CFD and Explicit Dynamics meshes Design Exploration for optimization analyses Finite Element Modeler (FE Modeler) for translating a NASTRAN and ABAQUS mesh for use in ANSYS BladeGen (Blade Geometry) for creating blade geometry Explicit Dynamics for explicit dynamics simulations featuring modeling of nonlinear dynamicsANSYS, Inc.

Introduction

ANSYS Workbench Overview

Training Manual

The Workbench environment supports two types of applications: Native applications (workspaces): Current native applications are Project Schematic, Engineering Data and Design Exploration. Native applications are launched and run entirely in the Workbench window.

Data Integrated Applications: current applications include Mechanical, Mechanical APDL, FLUENT, CFX, AUTODYN and others.

Introduction

D. The Workbench Environment

Training Manual

For most situations the Workbench GUI is divided into 2 primary sections (there are other optional sections well see in a moment):

The Toolbox

The Project Schematic


1-17


Introduction

The Toolbox The toolbox contains 4 subgroups: Analysis systems: predefined templates that can be placed in the schematic. Component systems: various applications that can be accessed to build, or expand, analysis systems. Custom Systems: predefined analysis systems for coupled applications (FSI, thermal-stress, etc.). Users can also create their own predefined systems. Design Exploration: Parametric management and optimization tools.

Training Manual


1-18


Introduction

. . . The Toolbox The systems and components displayed in the toolbox will depend on the installed products. Using the check boxes in the View All / Customize window, the items displayed in the toolbox can be toggled on or off. The toolbox customization window is normally left closed when not in use.

Introduction

The Project Schematic

Training Manual

The Workbench project schematic is a graphical representation of the workflow defining a system or group of systems. The workflow in the project schematic is always left to right. There are currently several applications which are native to Workbench, meaning they run entirely in the Workbench window: Project Schematic, Engineering Data and Design Exploration

Non-native applications (called data-integrated) run in their own window: Mechanical (formerly Simulation), Mechanical APDL (formerly ANSYS), ANSYS FLUENT, ANSYS CFX, Etc . . .

Blocks of cells can be deleted by RMB menu selection.

Introduction

. . . The Project Schematic

Training Manual

In this example a Static Structural analysis type is selected for the project schematic. From the toolbox the selection can be dragged and dropped onto the schematic or simply double clicked.


1-22


Introduction


Training Manual

By dropping applications and/or systems into various locations in the schematic, an overall analysis project is defined. Connectors indicate the level of collaboration between systems. In the example below a structural system is dragged and dropped onto a thermal system at the Model cell (A4). Before completing the operation notice there are a number of optional drop targets that will provide various types of linkage between systems (continued next page).


1-23


Introduction


Training Manual

By completing the operation from the previous page, notice the linkage here is only at the Model level and above. In this case there would be no thermal/structural coupling.

Notice too each system block is given and alphabetic designation (A, B, C, etc.).


1-24


Introduction


Training Manual

By dropping the structural system at the Solution level we obtain a structural system that is coupled to the thermal solution.

Notice, the candidate drop target indicates data will be shared from fields A2 to A4, and transferred from A6.


1-25


Introduction


Training Manual

A schematic can also be constructed by RMB and choosing to Transfer Data To New or Transfer Data From New. In using this RMB transfer feature all transfer possibilities (upstream and downstream) are displayed. These selections will vary depending on which cell in a particular system you highlight.


1-26


Introduction

. . . The Project Schematic Identifying cell states: Unfulfilled: missing upstream data. Attention required: may need to correct this or upstream cells.

Training Manual

Refresh required: upstream data has changed. Need to refresh cell (update will also refresh the cell). Update required: the data has changed and the output of the cell must be regenerated. Up to date. Input changes pending: cell is locally up to date but may change when the next update is performed due to upstream changes.

Introduction

Optional Workbench Windows

Training Manual

The View menu (and RMB) allows additional information to be displayed in the Workbench environment. Below, the geometry is highlighted and the properties are displayed.


1-28


Introduction

E. Workbench File Management

Training Manual

Workbench creates a project file and a series of subdirectories to manage all associated files. Users should allow Workbench to manage the content of these directories. Please do NOT manually modify the content or structure of the project directories. When a project is saved a project file is created (.wbpj), using the user specified file name (e.g. MyFile.wbpj). A project directory will be created using the project name. In the above example the directory would be MyFile_files. A number of subdirectories will be created in the project directory (explained next).


1-29


Introduction

. . . Workbench File Management Directory Structure: dpn: this is the design point directory. This essentially is the state of all parameters for a particular analysis. In the case of a single analysis there will be only one dp0 directory. global: contains subdirectories for each application in the analysis. In the example at right the Mech directory will contain the database, and other associated files from the Mechanical application. SYS: the SYS directory will contain subdirectories for each system type in the project (e.g. Mechanical, FLUENT, CFX, etc.). Each system subdirectory contains solver specific files. For example the MECH subdirectory would contain the results file, the ds.dat file, solve.out file and so on. user_files: contains input files, user macro files etc. that may be associated with a project.

Introduction

. . . Workbench File Management Archive: quickly generates a single compressed file containing all pertinent files. File is zip format and can be opened using the Restore Archive . . . utility in WB2 or any unzip program.
