Creating a Pole Domain

There are two types of structured block topologies for which a user would need a pole domain: a wedge-shaped block and a pyramid-shaped block. But before creating pole domains, make sure that your solver supports poles.

Two examples of where a pole domain would be used

In both cases, the pole domain must be created by hand in the Assemble Special task of the Create menu. In addition to the case of the pyramid block, a trick will be introduced for the creation of the two poles in the same XYZ location.

Pole Domain for a Wedge

Begin with a wedge-shaped geometry for which you wish to create a pole domain along one of the edges. Refer to the example and apply the steps to your own grid.

A wedge block with a pole domain
  1. Defaults
  2. Make sure the Connector frame is checked.
  3. Toggle on Dimension.
  4. 10
  5. Create, Draw Curves, Pole
  6. Click on point A.
  7. Apply (Pole 1 is saved.)
  8. Click on point B.
  9. OK (Pole 2 is saved.)

Now that the two poles have been created, the pole domain can be assembled.

  1. Create, Assemble Special, Domain
  2. Click on Pole 1.
  3. Next Edge
  4. Click on the connector in between the two poles.
  5. Next Edge (The pole domain is automatically completed and saved.)
  6. OK

Pole Domain for a Pyramid

Begin with a pyramid-shaped geometry for which you wish to create a pole domain in one XYZ location.

A pyramid block with a pole domain
  1. Defaults
  2. Make sure the Connector frame is checked.
  3. Toggle on Dimension.
  4. 10
  5. Create, Draw Curves, Pole
  6. Click on point A.
  7. OK (Pole 1 is saved.)

If a second pole with the same dimension is created in the same XYZ location as the first pole, Pointwise will assume that the poles are duplicates of each other and merge them into one pole. In order to create a second pole, the dimension must be different.

  1. Defaults
  2. Change the Dimension to 20.
  3. Create, Draw Curves, Pole
  4. Click on point A.
  5. OK (Pole 2 is saved.)

Now that the two poles have been created, the pole domain can be assembled.

  1. Create, Assemble Special, Domain
  2. Click on Pole 1.
  3. Next Edge
  4. Click on Pole 2.
  5. Next Edge
  6. Click on Pole 1.
  7. Click on Pole 2 (The pole domain is saved.).
  8. OK

If a square pole domain is desired, the dimension of Pole 2 can now be changed because a domain is fixed between the poles.

  1. Click on Pole 2.
  2. Click on Dimension on the toolbar.
  3. 10
