Modifying data as time progresses:

Some discharge data can vary with time (air temperature, noise power,...). Taking this into account, the program can do temporal averages in the calculation. In the CUSTIC software, these data are allowed to vary with time.

Variables that can be modified as time progresses:

Noise level (dB)

Temperature (degrees Celsius)

Relative humidity (%)

 

Commands for obtained data:

 

Calculation colours.- By means of this command, we will be able to change the colors of the isolines, of the maximum point and of the point sources.

 

 

 

Fonts.- This command is an auxiliary tool for making the maps of noise pollution. In this command we have two different options. We can choose: font size and source label (Yes/No).

 

 

 

Number of isolines.- This command is an auxiliary tool for making the maps of noise pollution. We will decide the number of isolines in the screen that we will take to make the representation. In certain situations, it can be interesting to have a high number of isolines for a better visualization. We will use this command before using the calculation command because this parameter should be perfectly defined before running the simulation. If you click the Number of isolines button, the next program window is shown:

 

 

In this window we will be able to choose the number of isolines that we want to have in our computer screen. To calculate the lines, the program also considers to the maximum point as a line.

 

Grid size.- The grid size is an important parameter in the configuration of the system. We will decide the number of calculation points in the grid that we will take to make the simulation. As we increase the number of points, the computer will take much more time in carrying out the calculation but the result will be much more exact. If you click the Grid size command, the next program window is shown:

 

 

 

In this window we will be able to choose the number of grid points (calculation points) that we want to have in the X-Axis. The number of points to calculate will increase quadratically with the number of grid points along the X-Axis N, that is to say, it will increase as N2.

 

 

 

Six different noise sources in the XZ plane considering topographic lines. It is shown isolines.
