•From the ribbon Model, click on the button in the group Add items.

•The Polygon tool is active. Design the geometry corresponding to the new object and finish the entry by pressing the key Enter.

•The Volumic source interface is displayed so that the parameters of the input polygon can be entered.

•Enter the geometric parameters:

oVertical: the distance between sources to be observed and the number of sources at a given height. These two values determine the total height of the source: total height = distance between sources x number of vertical sources.

oHorizontal: the distance between sources determines the density of point sources at a given height. The number of point sources at a given height can be determined by using the area of the polygon.

Total no. of sources = No. of horizontal sources x No. of vertical sources. The maximum number allowed is 500.

The positioning of point sources schema is automatically updated in accordance with the parameters.

•Enter the acoustic parameters:

oA Comment.

oA Nature. The button can be used to add a nature.

oThe name of the reference model. The model mode allows to select a model stored in the List of reference models (so previously created). This is useful when several sources share the same spectrum.

The button allows you to access the interface of the characteristics of the reference model (in view only mode).

oThe percentages of use for each period.

The corresponding spectrum window is accessed via the button or via the context menu:

The button allows to convert the source to spectrum mode. The interface is then modified.

The button allows to go to model mode. The interface is then modified again. Note that when you come back to Base, the model will be the first of the list and not the one that you could have set before to switch in Spectrum.

•Click OK to confirm.

 

The buttons allow to:

•Increase/Decrease spectrum by +/-1 or +/-10.

•Reset the spectrum to 0.

•Copy the spectrum.

•Paste the spectrum.
