HB Solution View

The HB Solution View node controls the properties of harmonic balance solution view for all selected blade passages of all blade rows in the simulation.



To create a harmonic balance solution view:

  1. Right-click Continua > Physics > Models > Harmonic Balance Flow and Energy and select New HB Solution View. This creates an HB Solution View node under the Solution Views node.
  2. Select the HB Solution Views node and select a view mode from the Mode property drop-down menu. Set a new value for the Flutter Amplification property at this time, if necessary.
  3. Select the HB Solution Views > Blade Rows > Blade Rown nodes, one by one, and set their properties.

The blade passages selected for all blade rows are shown in a Scalar scene under Scenes > Scalar Scene n.

HB Solution View Properties

Representation The name of the HB Solution View node. (Read only.)
Mode Specifies the mode in which to visualize the fields selected for the individual blade rows.
Physical Time

The physical time at which to visualize the blade row fields. This is the default mode.

Time Level

The time level at which to visualize the blade row fields.

Fourier Mode

The number of the mode (harmonic) at which to visualized the blade row fields.

Filtered Mode

The number of the filtered mode (harmonic) at which to visualize the blade row fields.

Flutter Amplification

Magnification factor for blade vibration. The default is 1 (no amplification).

See Harmonic Balance Field Functions Reference for a listing of the available fields.

Physical Time Mode

In this mode, the solution view shows the blade row fields at a given physical time.

Cycle Time is displayed to help you select the point in the rotation for visualization.

Physical Time Mode Properties

Physical Time The physical time at which to visualize the blade row fields.
Cycle Time The time taken to complete one rotation of the rotor. (Read only.)

Time Level Mode

In this mode, the solution view shows the blade row fields at a given time level—that is, at a given point in the repeating periodic flow.

Time Level Mode Properties

Time Level

The time level at which to visualize the blade row fields.

Fourier Mode

In this mode, the solution view shows the blade row fields for a given harmonic when the periodic flow is analyzed into a Fourier series.

Fourier Mode Properties

Mode The number of the mode (harmonic) at which to visualized the blade row fields.
Output Option The feature of the Fourier mode being visualized.
Real The real part of the Fourier mode.
Imaginary The imaginary part of the Fourier mode.
Magnitude The magnitude of the Fourier mode.
Phase The phase of the Fourier mode.

Filtered Mode

In this mode, the solution view shows the blade row fields for a given mode taken from the Filtered Modes Table under the Harmonic Balance Flow and Energy node.

Filtered Mode Properties

Mode The number of the filtered mode (harmonic) at which to visualize the blade row fields.
Output Option The feature of the filtered mode being visualized.
Real The real part of the filtered mode.
Imaginary The imaginary part of the filtered mode.
Magnitude The magnitude of the filtered mode.
Phase The phase of the filtered mode.

Blade Row

One Blade Row node appears under the HB Solution Views > Blade Rows node for each blade row. Enter the selection as an ordered pair in square brackets, with a negative integer for the number of lagging blades and a positive integer for the number of leading blades.

Examples:

  • [0, 0] is the original blade alone. This is the default.
  • [-9, 8] is nine lagging blades through eight leading blades.

Blade Row Properties

Blade Passage Selection

The blades in the passage selected for visualization.

Blade Passage Range

The number of blades available in the blade row. See Eqn. (340). (Read only.)
