Manage Positions/Transformations

Apply a transformation sequence on a set of nodes to change their position in the model.

Abaqus

Transformations are applied in the sequence in which they are listed in the Select Transformations dialog. The list of transformations can have unique transformations, or a given transformation can be repeated as many times as required. If there are changes made to the applied list of transformations, for example if a Transformation was deleted, the Position entity will be automatically updated to incorporate these changes. If you clear the Applied checkbox, the transformations will be undone in the reverse order in which they were applied.

  1. Open the Entity Editor for the Position entity you are adding a list of transformations to.

  2. In the Entity Editor, right-click on Transformations and select Select Ordered List from the context menu.
  3. In the Select Transformations dialog, click to add transformations.
  4. In the panel area, click transformations.
  5. Select a transformation.
  6. Click proceed.
  7. If necessary, add additional transformations.

    To remove transformations, select a transformation and click .

    To change the sequence of transformations, click .

  8. Click OK.

LS-DYNA

Apply a transformation sequence on a set of nodes, or a SolverSubmodel, to change their position in the model.

In the LS-DYNA solver profile, Position entity is used to manage *DEFINE_TRANSFORM and *NODE_TRANSFORM cards. Use the position entity to manage the transformations applied on a set of nodes or an Include_Transform. Position and transformations are managed in the Position/Transformation tool.

  1. In the Model Browser, right-click and select Position/Transformation from the context menu. Alternatively, right-click on an include file and select Transform from the context menu.
    The Create or Edit Position/Transformation dialog opens.
  2. Create a position.
    1. Click .
      A new position is created, and a list of entity attributes are displayed in bottom pane.
    2. Edit the position's attributes accordingly.

  3. Apply a transformation to the position.
    1. Select the position entity.
    2. Apply a new or existing transformation to the position.
      • Create a new transformation by clicking . Edit the transformation's attributes accordingly in the bottom pane.
      • Add an existing transformation by clicking and selecting a transformation from the Select Transformation dialog. Click OK when finished.

  4. Select the Applied checkbox for the position entity to apply the list of transformations.
    You can select the Applied checkbox from the Applied column in the first pane, or by modifying the position's attributes in the second pane.

Radioss

Apply a transformation sequence on a set of nodes to change their position in the model.

In the Radioss solver profile, there is no solver keywords mapped to the position entity. Use the position entity to manage the transformations applied on a set of nodes or a Submodel. Position and transformations are managed in the Position/Transformation tool.

  1. In the Model Browser, right-click and select Position/Transformation from the context menu.
    The Create or Edit Position/Transformation dialog opens.
  2. Create a position.
    1. Click .
      A new position is created, and a list of entity attributes are displayed in bottom pane.
    2. Edit the position's attributes accordingly.

  3. Apply a transformation to the position.
    1. Select the position entity.
    2. Apply a new or existing transformation to the position.
      • Create a new transformation by clicking . Edit the transformation's attributes accordingly in the bottom pane.
      • Add an existing transformation by clicking and selecting a transformation from the Select Transformation dialog. Click OK when finished.

  4. Select the Applied checkbox for the position entity to apply the list of transformations.
    You can select the Applied checkbox from the Applied column in the first pane, or by modifying the position's attributes in the second pane.

Tip:
  • Search for positions/transformations using the search field.
  • Change the sequence of transformations by clicking .
  • Remove transformations by selecting a transformation and clicking .

PAM-CRASH

Apply a transformation sequence on a set of nodes and elements, to change their position in the model.

In PAM-CRASH solver profile, Position entity is used to manage TRSFM cards. Use the position entity to manage the transformations applied on a set of nodes or elements. Position and transformations are managed in the Position/Transformation tool.

  1. In the Model Browser, right-click and select Position/Transformation from the context menu. Alternatively, select a keyword from the Solver Browser and select it, then right-click on the create position entity and select Edit from the context menu.
    The Create or Edit Position/Transformation dialog opens.
  2. Create a position.
    1. Click .
      A new position is created, and a list of entity attributes are displayed in bottom pane.
    2. Edit the position's attributes accordingly.

  3. Apply a transformation to the position.
    1. Select the position entity.
    2. Apply a new or existing transformation to the position.
      • Create a new transformation by clicking . Edit the transformation's attributes accordingly in the bottom pane.
      • Add an existing transformation by clicking and selecting a transformation from the Select Transformation dialog. Click OK when finished.
