Analysis Using The Dynatree Software - Fakopp DynaTree Manual

Analysis using the DynaTree software

In the rest of this subsection we will assume that data is successfully transferred from the
inclinometer(s), extensiometers and the anemometer to a PC that runs MS Windows and has the
DynaRoot-DynaTree software installed. After starting the program, first enter the options menu on
the top left corner. See Figure 31 for a screenshot of the menu. This is where you can choose your
language (default is English) and turn on DynaTrunk function.
If you have only inclination and wind data, use the program same as the program for DynaRoot. If
you measured the extension of the trunk as well, turn on the DynaTrunk function. C1 and C2 are the
calibrations (which is usually different for each estensiometers. See the calibration data in the
package.) Please take care of using the correct information of the proper extensiometer.
Figure 31: The options menu
The maximum merge error specifies how much wind and inclination data may be shifted from one
another. Statistical window size specifies the length of the interval, over which statistical parameters
of wind velocity and inclination is generated. You only need to specify this information once.
After returning to the data window (see Figure 32), you can specify the location of the tree
(optional), and the location of the source data. First you need to choose the type of anemometer
(this is required because of the different data formats). Currently, there are two types of
anemometers included in the software: a cup type mechanical anemometer, or the FAKOPP
ultrasonic anemometer. You can enter the name and location of the wind velocity source file and the
inclination data folder, or use the browse button next to the data field. Finally, you need to supply
the maximum wind velocity, for which you wish to calculate the Safety Factor. After entering all of
the information, hit the calculate button.
