HM-3650: Create Shapes With Record

In this tutorial, you will change a bead using the Node Edit > align node subpanel and record the shape function. You will then reflect the shape to the other side of the mesh to complete the mesh update.

The Record panel gives you the flexibility of making changes to the mesh using panels outside the HyperMorph module and saving them as shapes.

This exercise uses the floor.hm file, which can be found in the hm.zip file. Copy the file(s) from this directory to your working directory.


Figure 1.

Open the Model File

In this step, you will open the model file, floor.hm.

  1. Open the model file, floor.hm.
  2. Review the model.

Record Nodal Movements

In this step, you will record nodal movements.

  1. From the menu bar, select Morphing > Free Hand, then select the record subpanel.
  2. Click start.
  3. Click return.

Change the Bead Profile

In this step, you will change the bead profile.

  1. From the menu bar, select Geometry > Edit > Nodes > Align to enter the align node subpanel.
  2. Select the nodes shown below for the 1st end and 2nd end.


    Figure 2.
  3. Select the nodes between the selected nodes to align the nodes to the 1st end: and 2nd end: nodes.
  4. Repeat the same process to align the next row of nodes.


    Figure 3.
  5. Select the nodes between the selected nodes to align the nodes to the 1st end and 2nd end nodes.
  6. Repeat the same process to align the next row of nodes.

  7. Click return to exit the panel.

Stop the Recording

In this step, you will stop the recording.

  1. From the menu bar, select Morphing > Free Hand, then select the record subpanel.
  2. Click finish.
    This stops the recording process.

Save the Morphed Shape

In this step, you will save the morphed shape.

  1. Go to the save shape subpanel.
  2. Set name= to Morph1.
  3. Toggle the save option to as node perturbations.
  4. Click save.


    Figure 5.
  5. Click undo all to bring the model to its original position before morphing.

Create a Coordinate System

In this step, you will create a coordinate system.

  1. From the menu bar, select Geometry > Create > Systems > Axis Direction.


    Figure 6.
  2. For origin, select the node with the tag origin.
    • For x-axis select the node with tag x-axis.
    • For xy-plane, select the node with xy-plane.
  3. Click create.
  4. Click return to exit the panel.

Create Symmetry

In this step, you will create symmetry.

  1. From the menu bar, select Morphing > Create > Symmetries.
  2. Set name= to symm1.
  3. For symmetry type use 1 plane.
  4. For align with use x-axis.
  5. Select the syst created in Step 6.
  6. Click create.
    1 plane symmetry is created with a square symbol.
  7. Click return to exit the panel.


    Figure 7.

Reflect the Shape

In this step, you will reflect the shape.

  1. From the menu bar, select Morphing > Create > Shapes, then select the apply shapes subpanel.
  2. Under shape, change the option to reflect shapes.
  3. Under reflect shapes, change the option to apply & create.
  4. For shape, select Morph1.
  5. For symmetries, select symm1.
  6. Click reflect.
    The shape (Morph1) is reflected to the other side. Also, the reflected shape has the same name with the suffix 1. The changes that you made on one side are thus transferred to the other side.
