Utility Menu > File > Save as…

RESUME command: restore the database from the db file back into memory

Utility Menu > File > Resume Jobname.db

Utility Menu > File > Resume from…

  • Lunch Ansys
  • Load a db file
  • Navigate the menu
  • Call the help system
  • Plot geometric entities: lines, areas, volumes
  • Instructions found in Practice-1.pptx
  • This page contains no technical data subject to the EAR or the ITAR.
slide12

Select Logic

Select Logic allows selection of a subset of entities and operate only on those entities.

  • Three step process:
  • Subset selected
  • Operation performed on subset
  • Full set reactivated

slide13

Select Logic

  • Selection types:
  • From Full: selects a subset from the full set of entities.
  • Reselect: selects (again) a subset from the current subset.
  • Also Select: adds another subset to the current subset.
  • Unselect: deactivates a portion of the current subset.
  • Invert: toggles the active and inactive subsets.
  • Select None: deactivates the full set of entities.
  • Select All: reactivates the full set of entities.

slide14

Components

  • Components are user-named subsets of entities.
  • The name can then be used in dialog boxes or as arguments to commands.
  • A group of nodes, or elements, or keypoints, or lines, or areas, or volumes can be defined as a component.
  • Only one entity type is associated with a component.
  • Components can be selected or unselected. When you select a component, you are actually selecting all of the entities in that component.
  • Component Manager can be accessed from:
  • Util Menu > Select > Component Manager
  • This page contains no technical data subject to the EAR or the ITAR.
slide15

Picking

  • Picking existing entities to perform an operation.
  • Picker window allows to enter entity numbers directly.
  • All entities can be picked with the Pick All button.
  • Mouse button assignments for picking:
  • Leftmouse button picks (or unpicks) the entity or location closest to the mouse pointer. Pressing and dragging allows you to “preview” the item being picked (or unpicked).
  • Middle mouse button does an Apply. Saves the time required to move the mouse over to the Picker and press the Apply button. Use Shift-Right button on a two-button mouse.
  • Right mouse button toggles between pick and unpick mode.
  • This page contains no technical data subject to the EAR or the ITAR.
slide16

Picking

  • Pick hotspot locations:
  • Areas and Volumes have a hotspot near the centroid of the solid model entity.
  • Lines have three hotspots - one in the middle and one near each end.
  • When you are required to “pick” an entity, you must pick on the hotspot.
  • This page contains no technical data subject to the EAR or the ITAR.
slide17

Work Plane

  • Working Plane - a movable, 2-D reference plane used to locate keypoints.
  • Default position of the WP origin is the global origin. It can be moved or rotated as needed.
  • WP defined by the XY plane. WP is infinite.
  • To position the WP use Util Menu > WorkPlane > Offset WP by Increments

Translate

Rotate

  • This page contains no technical data subject to the EAR or the ITAR.
slide18

Coordinate Systems

  • Types of Coordinate systems:
  • Global and local coordinate systems: used to locate geometry entities(nodes, keypoints, etc.)
  • Display coordinate system: determines the system in which geometry items are listed or displayed.
  • The nodal coordinate system: defines the degree of freedom directions at each node.
  • The element coordinate system: determines the orientation of material properties.
  • The results coordinate system: used to transform nodal or element results data to a particular coordinate system for listings, displays, or general postprocessing.
  • This page contains no technical data subject to the EAR or the ITAR.
slide19

Coordinate Systems

  • Global Coordinate System
  • The global reference system for the model.
  • Can be se to Cartesian (csys,0), cylindrical (csys,1), or spherical (csys,2).
  • Global coordinate systems can not be changes are always available.
  • To change the coordinate system use the command csys,”coordinate id”

Coordinate Systems

  • Local Coordinate System
  • A user-defined coordinate system at a specified location. Coordinate system ID should be 11 or greater.
  • Several ways to define:
    • At WorkPlane origin
    • At specified coordinates
    • At existing keypoints or nodes
    • Can be Cartesian, cylindrical, or spherical.
    • Can be rotated about X, Y, Z axes.

Practice 2

  • Practice 2 will show how to:
  • Pick entities
  • Manipulate the WorkPlane
  • Define an manipulate Coordinate systems
  • Perform Selections
  • Component creation
  • Instructions found in Practice-2.pptx
  • This page contains no technical data subject to the EAR or the ITAR.
slide22

Solid Modeling

  • Solid Modeling: the process of creating solid models.
  • Definitions:
  • A solid model is defined by volumes, areas, lines, and keypoints.
  • Volumes are bounded by areas, areas by lines, and lines by keypoints.
  • Hierarchy of entities: from low to high:
    • Lower  Higher
  • keypoints < lines < areas < volumes
  • Cannot delete/remove an entity that belongs to a higher-order entity.

Volume

Area

Line

Keypoint
