    Introduction to Advanced Topics

  • 3 2015 ANSYS, Inc. March 2, 2015

    Import and data transfer related properties Applicable for imports Most of the settings done through

    Basic Geometry Options

    and Advanced Geometry Options

    Basic Properties Parameters option for importing

    parameters defined in CAD package

    Parameter Key filters the parameters from CAD that enter Workbench

    If not specified, all parameters enter WB

    Basic Properties (cont.) Named Selection

    Define in CAD & transfer to WB

    Filter under WB

    Set to NS (by default) remove it to import all parameters

    Activate WB option

    Geometry import / named selections

    Advanced Properties Select Use Associativity to establish association between CAD

    and WB

    Import defined CAD properties :

    Coordinate Systems,

    Work Points, etc.

    Smart CAD Update

    Changes made in other options get updated in the mode

    Import II

    In Design Modeler page Multiple imports possible Appends geometries

    Import III

  • 6 2015 ANSYS, Inc. March 2, 2015

    Export parameters from CAD to Workbench Parameter change in CAD reflects in

    Workbench and vice versa

    Direct connection in UG NX

    Bi-directional connectivity Launch Workbench from CAD System

    CAD Connections : Approach II

    Bi-directional CAD connectivity

    Attach to Active CAD Geometry Imports active CAD geometry in DM Can attach only saved CAD sessions

    Bi-directional import from DM

  • 7 2015 ANSYS, Inc. March 2, 2015

    Helps execute a set of operations repeatedly with different input values Useful for analyzing multiple design points

    By modifying geometry/topology parameters

    Parameters can be either used for : Sketch dimensions, Plane creation inputs, 3D operation values, etc.

    Parameters can be linked with each other through expressions Defined in Design Modeler or Workbench

    Parameters can be controlled from Workbench No need for Design Modeler to be opened

    CAD Connection

    CAD Connections & Parameterization

    Parameterization

    What is it ?

  • 8 2015 ANSYS, Inc. March 2, 2015

    Types of Parameters

    Changes the dimensions or locations of a given feature Does not necessarily change the total

    number of entities in the model

    Geometric parameters

    Modifying the feature itself by adding or removing geometry Can change total number of entities in the

    model

    Topological parameters

    Parameterized

    number of copies

    in a pattern

    Parameterized

    dimension

    Creating Parameters in Design Modeler

    Procedure

    Any input prefixed with the symbol can be parameterized Toggle to D to parameterize that particular input

    Default Parameter Name Pattern Feature Name.Dimension Reference

    Parameter name can be changed

    Example:

    A dimension reference (H1) for a sketch created on the XYPlane = XYPlane.H1

    A dimension reference (FD1) for Extrude1 = Extrude1.FD1

  • 11 2015 ANSYS, Inc. March 2, 2015

    Parameter Manager

    Accessible from the Toolbar or Tools menu

    Design Parameters tab List the existing parameters & assigned values

    Parameter/Dimension Assignments tab Contains expressions

    relating the original dimension reference to the value set in the Design Parameters tab

    This 2 defined parameters become obsolete and can be suppressed (or deleted)

    Create the needed expressions & Check to evaluate them

  • 12 2015 ANSYS, Inc. March 2, 2015

    Parameter Manager

    Parameters created in Design Modeler can be managed in:

    Parameter Editor in DM Parameter Set in WB

    Expression can be created in the Outline of All Parameters in WB

    Multiple Design Points can be created using different values of the parameterized independent variable

    Linked together &

    Updated in background

    Advanced Sweep Options

    Sweep Options

    Scale Taper or expand the Profile as it is swept along the path of Sweep

    Twist Specification No Twist : Helical sweep is not created

    Turns : Specify number of turns to complete over the path length

    Pitch : Specify length per 1 full turn

    4m

    Body Operation: Move, Align and Orient Using By Direction option, one can align bodies by using alignment vertices for aligning axes of bodies and orienting bodies with respect to each other.

    User needs to select bodies, pair vertices for Source & Destination Move and directions for Source & Destination Align and/or Source & Destination Orient

    Coordinate File for 3D Curve

    A coordinate file must be a simple text file in the following format:

    The pound sign (#) indicates a comment Empty lines are ignored Data consists of five fields, all on one line, separated by

    spaces and/or tabs:

    Group number (integer)

    Point number (integer)

    X coordinate

    Y coordinate

    Z coordinate

    A data line cannot contain the same Group number and Sequence number as a previous data line.

    For a closed curve, the point number of the last line should be 0. In this case, the coordinate fields are ignored.

    Managing External Files The WB project file structure provides a directory named

    user_files

    The WB protects this directory and ensures that it is managed and archived appropriately.

    Files from separate applications that are associated with this project can be safely stored in this directory.

    CAD data (imported geometry data) should be stored here, especially if you intend to transfer the project to another computer.

    When the project is reopened and the CAD data is not saved in user_files WB will prompt you to locate the file:

    From the View Menu, select Files.

    Right click on the relevant file in the list and select Repair filename.xxx.

    Browse to the file in the user_files folder.

    The new path will be saved with the project.
