Design Exploration
Once the baseline model is prepared, you can define morph volumes, morph geometry, create design shapes and run DOE studies. These tool work for both AcuSolve and ultraFluidX-based workflows.
Morph
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
Morph Volumes
Morph volume entities are highly deformable six-sided prisms which surround a portion of the FE mesh, and can be used to manipulate a mesh by manipulating the shape of the morph volume.
Split/Combine Morph Volumes
Use the Morph Volumes: Split/Combine tool to split morph volumes using a single or multiple locations along an edge, combine adjacent morph volumes along shared faces, join pairs of separate morph volumes, or equivalence any number of morph volume faces using a search distance.

- Morph
  Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.
  - Morphing Preferences
    Define morphing preferences.
  - Morph Constraints
    Morph constraint entities restrict or prescribe the movement of nodes during morphing, with a variety of available methods and dimensional values. These constraints are valid across all available morphing approaches and can be individually activated or deactivated at any time, even in between morphs or applying shapes.
  - Free Morph
    Use the Free tool to morph mesh by moving nodes, handles, or domains, by applying shapes, or by mapping to geometry.
  - Proximity Morph
    Use the Proximity tool to morph mesh using a simple distance or perturbation value around selected nodes, faces, edges, or shapes.
  - Morph Volumes
    Morph volume entities are highly deformable six-sided prisms which surround a portion of the FE mesh, and can be used to manipulate a mesh by manipulating the shape of the morph volume.
    - Load/Save Morph Volumes
      Use the Morph Volumes: Convert tool to load or save morph volumes from or to a file.
    - Enclose Morph Volumes
      Use the Morph Volumes: Enclose tool to create morph volumes with rectangular or circular shapes. Enclosed mesh and connectors are automatically registered to the enclosing volumes by default.
    - Move Morph Volumes
      Use the Morph Volumes: Move tool to morph or adjust morph volumes by moving vertices/handles, edges, and faces with graphical manipulators.
    - Split/Combine Morph Volumes
      Use the Morph Volumes: Split/Combine tool to split morph volumes using a single or multiple locations along an edge, combine adjacent morph volumes along shared faces, join pairs of separate morph volumes, or equivalence any number of morph volume faces using a search distance.
    - Edit Morph Volume Edges
      Use the Morph Volumes: Edges tool to adjust the interaction of the morph volumes by adding or removing handles on the edge of the volumes or changing the tangency of the volumes.
    - Register Morph Volumes
      Use the Morph Volumes: Register tool to review and edit the contents of morph volumes. Only registered contents will morph when morphing morph volumes. Entities that can be registered to morph volumes are nodes and connectors.
  - Shapes
    Shapes are collections of perturbations from the initial configuration of the FE mesh before the morph.
  - Domains
    Domain entities divide the model into different domains during morphing.
  - Handles
    Handle entities control the shape of domains during morphing.
  - Symmetries
    Symmetry entities define planes of symmetry within a model so that morphs can be applied in a symmetric fashion.
  - Undo All Morphs
    Undo all morphs and return to the original state of the model.
  - DOE Studies
    Once morphing is done, you can create shapes and design variables and submit DOE studies. The DOE study tool can be used for shape and CAD parameter DOEs, and for Automation. The purpose of this tool is to provide automation files so you can manually modify them and carry out DOEs.

Split/Combine Morph Volumes

Use the Morph Volumes: Split/Combine tool to split morph volumes using a single or multiple locations along an edge, combine adjacent morph volumes along shared faces, join pairs of separate morph volumes, or equivalence any number of morph volume faces using a search distance.

From the Morph ribbon, click the Morph Volumes > Split/Combine tool.

Figure 1.

Choose the operation to perform from the guide bar.

Option	Description
Split	Pick a split location on a morph volume edge using the mouse. Reposition the split location using snaps, or use the microdialog to change number of splits. - Toggle between splitting the selected edge with a single cut or multiple cuts . Use the text box to adjust the position of a single cut as a ratio of the edge length, or adjust the number of multiple cuts - Enforce tangency of the adjacent volumes after the split. - Generate morph handles at the vertices of the split location (recommended). Disabling this option will not allow any morphing of the vertices, edges, or faces at the split location.
Combine	Combine rows of adjacent morph volumes that share a common face. Use the microdialog to toggle tangency of the new combined volume with its neighbors. - Enforce tangency of any adjacent volumes after the combination. - Keep morph handles at the vertices of the combined location.
Join	Join morph volumes that do not share a common face. Use the microdialog to choose the join location and toggle tangency. - Choose the location to join the volumes. Either move the faces of both volumes to their midpoint, or keep the face of the first or second selected volume. - Enforce tangency of the newly joined volumes. - Automatically register any new inner nodes to their respective enclosing volumes after they are joined.
Equivalence	Bulk join any non-adjacent morph volumes that have faces within the specified search distance. Use the microdialog to optionally restrict the search to only selected volumes, and toggle their new tangency. - Use this button to optionally select candidate volumes to equivalence. If left empty all volumes are considered candidates. - Enforce tangency of the newly joined volumes. - Automatically register any new inner nodes to their respective enclosing volumes after they are joined.

Click the action button in the microdialog to confirm the operation.
