To compute the TPA syntheses in multiple receivers, you need Blocked Forces. You can calculate Blocked Forces in SOURCE, using the following methods:
To calculate the TPA syntheses at the target sensors, SOURCE needs the FRF/NTF of the receivers. We recommend importing a DIRAC project (if available) because it gives the most efficient workflow and unlocks additional functionalities.
To import a DIRAC project containing FRF/NTF, complete the following steps:
If you did not use DIRAC to measure the FRF/NTF, you can import ATFX and MAT files. To import the data, complete the steps at this link.
In the import dialog, you can perform additional steps. We recommend to:
Before starting the calculation, you need to correctly set up the channels. In particular, you have to:
The first step when setting up the channels consists of adding the target channels to the Masters.
To set them as masters, complete the next steps:
If this step is performed correctly, the channels will turn green. Numbers will also appear in the Mapped to column.
If the channels were not mapped automatically to the Masters during the import, it is necessary to map them.
To map the channels to the masters, complete the next steps:
The next step consists of setting the correct channel type. For this type of analysis, you need to set the following types:
To change the channel type, complete the next steps:
Test assemblies are a key feature when calculating Blocked Forces with one setup and using them for TPA synthesis in other target assemblies. They are used to define which data of the analysis should be used for characterization and which for the TPA syntheses.
To set test assemblies correctly, complete the following steps:
The last step consists of calculating the TPA syntheses. You do not need to create a new analysis, but you can use the one you made for calculating the Blocked Forces. This is the case if you have correctly set up the Test assemblies as explained in the paragraph above.
To calculate the TPA syntheses, complete the following steps:
