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.
Morphing
Rapidly change the shape of the FE mesh without severely sacrificing the mesh quality.

  - 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.
  - 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.

Morph Definitions and Dialog Options

Morph Definitions

Parts

Only selected parts will be morphed.
If no parts are selected, all parts will be considered for morphing.
If parts connected to the selected parts are not in the selection, you will have to manually define fixed points at boundaries of connected parts.

Control Volumes

Any nodes outside of the selected box will not be morphed.
Only one box definition is supported.

Active control points

Points which define the area to be morphed
Either create points by clicking on geometry or use the button to select already created control points.
Nodes within sphere drawn from each control point with impact radius will be morphed.

Fixed control points

Points which constraint node movement of the nodes around.

Either create points by clicking on geometry or use the

button to select already created control points.

Preview

Clicking on preview will create an animated preview of the shape.

If the shape is already created with morph setting, clicking on preview will overwrite the existing shape.

Dialog Options

Translation vector: A measure of how much control points will be moved.
Impact radius: Defines the scope of nodes which will be morphed on moving control points. Nodes within a sphere drawn from each control point within impact radius will be morphed.; Impact radius should be bigger than translation magnitude of control points.
Define symmetry: Enables symmetry morphing along a plane. With this option, you can replicate morphing on both side of a plane. You must define the plane normal and center point of the plane.; Use the manipulator to interactively define plane.
