The example used for this tutorial is located in the folder Examples\Geometry Building Model\ and called Geometry Building Model.amp

This tutorial comprises:

Preliminaries

When no measurements are uploaded the task view looks as follows


As shown earlier in the Geometry Generator tutorial, the considered building model has two floors. Each of these floors has been measured in three locations and the measurements has been split into two test setups. Each measurement setup comprises two reference sensors at fixed positions and two moving sensors. The total number of channels used in each test setup is therefore four.

Defining a Test Setup

To define first test setup select the Measurement Project (root item) in the Data Organizer window and press the Insert Object button:

This command will insert a new Test Setup which we immediately will rename to First Floor Measurement, as shown below:

Importing Measurements

We are now ready to upload the measured data from a binary file storing each measurement channel one by one. The measurements for the first floor are stored in the Measurement_1.bin file located in the folder Examples\Geometry Building Model. To import them click on the Test Setup item called First Floor Measurement and the Import button:

An Open File dialog will appear, where one should select the SVS Binary File type to open the measurement file. The software will ask if the Test Setup should be called the same as the file name. We decline.

The uploaded measurement channels appear in the Data Organizer as four Channel Items, and the measurements themselves can be viewed in the Measurement Explorer as shown below.

The Sampling Frequency (150 Hz) is setup in the Property window, which is activated by clicking on the Data Sets window

This step is necessary in case when the SVS Binary Format does not hold the information about the sampling interval or the sampling frequency of measured data. When the value is entered the user is asked to update other Data Sets

Now we repeat everything for the second measurement that has been made.

  1. Click the Measurement Project item and then the Insert Object button.
  2. Click on the inserted Test Setup item and rename it to Second Floor Measurement.
  3. Click the Import button and browse for the Measurement_2.bin binary file in the Building Model folder.
  4. Click the Data Sets window to activate the Properties of the Data Set of the second Test Setup, then enter the Sampling Frequency as 150 Hz.

Finally, we go back to the Measurement Project item, and click on it in the Data Organizer. In the Properties window we then change its name to Geometry Building Model Tutorial Examples. And click on Save as and save the project as Geometry Building Model Final Result.amp. The final work is shown below, and we are now ready for the DOF assignment.
