Transfer 2D Parametric Data in a .csv File to a 3D Surface Model

Use this method to map data from an old geometry model to a new geometry model during CAD parametric updates. This method uses geometry to node associativity.

In this example you will learn that though the u, v values are used as discrete data from a .csv file, a 2D mesh using the u, v locations is created internally. The shape function mapping is used in the 2D u, v space.
  1. In the Model Browser, right-click and select Create > Field from the menu.
  2. In the Entity Editor, edit the field's corresponding values:


    Figure 1.
    1. Set Type to continuous.
    2. Set System Type to parametric.
    3. Set Source to .csv file.
    4. In the File field, locate the .csv file containing the rectangular array of u, v data.
  3. Import the new model in HyperMesh.
  4. Mesh the surface of the model. The surface of the model should be associated with the target mesh. Every node should be mapped to a u, v.
  5. In the Model Browser, right-click on the field entity and select Realize from the menu.
  6. In the Field Realization dialog, define the realization settings:


    Figure 2.
    1. Using the Entity: Element selector, select the elements to map.
    2. Using the Surface: selector, select the surface to map.
    3. Using the Node(0,0) and Node(1,1) selectors, select the two nodes that coincide with (0,0) and (1,1) of the u, v surface. You can rotate the position by selecting two nodes which define the corner locations of the u, v.
    4. Click Apply.
      The 2D parametric data is mapped to the model.
