displacement vector (x = 4, y = 5, z = 0)
Fig. 22: View at the x-y plane. The house is shifted by the vector (x = 4, y = 5, z = 0).
All length specifications in meters.
Now the house is at the wanted position in the space. Confirm your input by clicking "OK"
and the house will be added to the actual project and will be shown in the 3D view.
8.4 Save data
Now you have defined the target plane and the shadow-throwing house and can start with
the simulation. To go on working with the project later on, it is now recommended to save the
data. For this, click the items "Project – Save as …" in the main menu and give your data file
a representing name. The extension ".dat" will be added automatically.
8.5 VRML view of the project data
If you want, you can also display your project in an external 3D viewer. Click the buttons
"Project – VRML view" to do so. If the program does not find a VRML player on your system,
please follow the instruction given in Chapter 3.12.
8.6 Simulation
If all data have been set correctly, you can now begin with the calculation of shading of the
collector. Thereby, you have the choice between the "Online output" and the "Fast pass
through".
In the “Online output” (see Chapter 4) you can look at the shading of the collector at a (user-)
given time. Thereby, the percentage of shading as well as further results of the calculations
are also given numerically.
At the Pass through of simulation (see Chapter 5) one has to define a start and an end time
as well as the interval between two simulation steps. After clicking the button "Start
simulation" the shading of the collector for this given period will be calculated and the results
will be saved in the mean-value and the report file (see Chapter 6).
