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.
Shapes
Shapes are collections of perturbations from the initial configuration of the FE mesh before the morph.
Convert Shapes
Convert a shape to node perturbations, handle perturbations, an mvol shape, forces, temperatures, pressures, or displacements.

- 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.
  - Shapes
    Shapes are collections of perturbations from the initial configuration of the FE mesh before the morph.
    - Create Shapes
      Create and apply morphing shapes. Shapes can be created by morphing or by converting load collectors.
    - Delete Shapes
      Delete selected shapes.
    - Record Node Movements
      Record node movements using other HyperMesh CFD tools and save them as a shape.
    - Animate Shapes
      Animate selected shapes.
    - Convert Shapes
      Convert a shape to node perturbations, handle perturbations, an mvol shape, forces, temperatures, pressures, or displacements.
    - Check or Smooth Shapes
      Use the Check/Smooth function to check the element quality of shape combinations and optionally smooth the shapes to improve the element quality when applied individually or as part of a combination of shapes.
    - Automatically Generate Shapes
      Use the Autoshape function to automatically generate multiple shapes for individual handles or domains.
    - Import Shapes
      Import saved shapes from a file.
    - Export Shapes
      Export selected shapes.
  - 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.

Convert Shapes

Convert a shape to node perturbations, handle perturbations, an mvol shape, forces, temperatures, pressures, or displacements.

From the Morph ribbon, click the Shapes tool.

Figure 1.

The Edit Shapes dialog opens.
Right-click on a shape and select Convert.
The Convert Options dialog opens.

Select an option from the Convert shapes drop-down menu.


Conversion option	Action
to node perturbations	Convert the selected shapes to pure node perturbations. Shapes converted to node perturbations will be unaffected by changes to domains and handles but take up more memory.
to handle perturbations	Convert the selected shapes to handle perturbations if possible or a combination of handle and node perturbations if it is not possible to capture the shape with pure handle movements. Shapes converted to handle perturbations may be affected by changes to domains and handles but take up less memory.
to mvol shape	Convert a shape which perturbs nodes or handles attached to morph volumes into one which has only handle perturbations for handles on morph volumes. All other perturbations are discarded. If the shape is applied it will morph any nodes registered to the affected morph volumes. Unlike to handle perturbations, this option will not preserve node perturbations due to things such as active constraints, and is useful for reverting a shape into pure handle movements and reapplying it with a different set of active constraints.
to forces	Create a new load collector for each selected shape with the XYZ perturbations at each node of each shape converted into XYZ values of force vectors at each node for each load collector. The original shape will be preserved and does not need to be converted to node perturbations before conversion to forces.
to temperatures	Create a new load collector for each selected shape with the magnitude of the perturbations at each node of each shape converted into temperature values at each node for each load collector. The node perturbations may lie along any axis and positive and negative temperatures can be preserved by making sure that the nodes are perturbed in only positive or negative directions. The original shape will be preserved and does not need to be converted to node perturbations before conversion to temperatures.
to pressures	Create a new load collector for each selected shape with the XYZ perturbations at each node of each shape converted into XYZ values of pressure vectors at each element for each load collector. Note: Pressures must be averaged from nodes to elements during the conversion and thus some information maybe lost. This conversion method has two options. normal to elems Align the pressures with the element normals regardless of the direction of the node perturbations. If not, the pressures will be created in the direction of the node perturbations. apply to partially affected elems Apply reduced pressures to all elements touching a perturbed node. If not, a pressure will only be created for elements where every node is perturbed. The original shape will be preserved and does not need to be converted to node perturbations before conversion to pressures.
to displacements	Create a new load collector for each selected shape with the XYZ perturbations at each node of each shape converted into XYZ values of enforced displacements at each node for each load collector. This conversion method has the option fix directions with zero perturbations which, if checked, will create an enforced displacement for all three translational components for a node even if the displacement for one or two of those components is zero. If not checked, any translations which have zero perturbations will not have an enforced displacement created in that direction. The original shape will be preserved and does not need to be converted to node perturbations before conversion to displacements.
