4.8.2. Outer Wall

Set the conditions on the outer wall (BS_2).

  1. Select the Zero wall velocity (vn=vs=0) along BS_2 (default) option.

  2. Click Modify.

  3. Select Normal and tangential velocities imposed (vn, vs), which is the default setting from the list of choices.

    Ansys Polydata will request input of the normal and tangential velocities.

  4. Click Upper level menu to accept the default value of 0 for the normal velocity (vn).

  5. Repeat the procedure to accept the default value of 0 for the tangential velocity (vs).

    Ansys Polydata will then ask you to confirm that the angular velocity is equal to 0 (Figure 4.17: Confirming an Angular Velocity of 0 on the Outer Wall).

  6. Click Yes to accept this default condition.
