Sensor Selection Configuration dialog box
| Algorithm | |
|---|---|
| Select Algorithm | Specifies the algorithm used in the sensor selection.Min-MACMinimizes the values of the off-diagonal elements in the MAC matrix by adding specified numbers of uniaxial and/or triaxial sensors from a candidate set to a required set of DOFs.MODMACReduces the values of the off-diagonal elements in the MAC matrix to a specified limit by adding a maximum number of candidate DOFs to an optional, initial set of DOFs. |
| Settings | |
| Number of Uniaxial Sensors | Appears when Select Algorithm is set to Min-MAC.Displays the number of uniaxial sensors contained in the selected sensor configuration. A node can have up to three uniaxial sensors. |
| Number of Triaxial Sensors | Appears when Select Algorithm is set to Min-MAC.Displays the number of triaxial sensors contained in the selected sensor configuration. A node can have only one triaxial sensor. |
| Maximum Number of DOFs | Appears when Select Algorithm is set to MODMAC.Sets the maximum number of possible DOFs from the combination of initial and candidate DOFs. |
| MAC Value Limit | Appears when Select Algorithm is set to MODMAC.Sets the limit value for the maximum off diagonal elements in the MAC matrix. |
| Sensor Type | Appears when Select Algorithm is set to MODMAC.Specifies the sensor type.UniaxialIndicates that the sensor has one active translational DOF.TriaxialIndicates that the sensor has three active translational DOFs. |
| Name | Sets the name of the sensor configuration. |
