Acoustic Monopole dialog box (Simcenter Nastran)
| Name | |
|---|---|
| Name | Sets the name of the acoustic monopole. |
| Description | Sets description for the acoustic monopole. |
| Destination Folder | |
| Load Container | Specifies the folder in the Simulation Navigator in which to store the acoustic monopole boundary condition.The list includes the root container and folders that you created using the New Folder command in the Load Container. |
| Folder Manager | Displays a hierarchical list of folders.To create a new folder, right-click any level of the hierarchy and choose New Folder. |
| Location | |
| Specify Point | Specifies the spatial location of the acoustic monopole.If the distance from the monopole to the 2D boundary mesh is less than the closest element size, the software may not accurately compute local acoustic scattering. Therefore, we recommend that you locate the monopole no closer than one element length from the 2D boundary mesh.If you require the monopole to be very close to the mesh, local mesh refinement may be required for an accurate solution of nearby acoustic scattering.Select a node or a point on the mesh in the graphics window, or click Point Dialog to open the Point dialog box, where you can define the location of the acoustic monopole in several different ways.For more information, see Point dialog box. |
| Magnitude | |
| Amplitude | |
| Specifies the constant complex excitation with real and imaginary parts, constant complex excitation with magnitude and phase angle, or the frequency dependent complex field values. | |
| Format | Specifies how the excitation is defined. |
| Real | Available when Format is set to Real/Imaginary.Sets the real component of the magnitude of the excitation. |
| Imaginary | Available when Format is set to Real/Imaginary.Sets the imaginary component of the magnitude of the excitation. |
| Magnitude | Available when Format is set to Magnitude/Phase.Sets the magnitude of the excitation. |
| Phase | Available when Format is set to Magnitude/Phase.Sets the phase angle of the excitation. |
| Specify Field | Available when Format is set to Field.Specifies the frequency dependent complex field values. |
| Power | |
| Power | Sets the magnitude of the power. For more information, see Additional magnitude options. |
| Specify Phase for Equivalent Amplitude | Available only when Specify Phase for Equivalent Amplitude option is selected.Sets the constant value of phase angle. For more information, see Additional magnitude options. |
