Details on Component Detection in the Settings Ventilation
Information about the section Component detection in the Settings dialog of the duct network calculation.
In this section, specify global settings for the detection of components, pipes and ducts that are to be considered during calculation.
You are here:
System Types
Extract air..., Supply air..., Outside air..., Exhaust air...
Open the Select System type(s) dialog, in which you specify which system types belong to the selected calculation type.
The system types are usually selected automatically for each calculation type. In the headline of the Select System type(s) dialog, the information <Automatic> is displayed. If you select one or more system types by yourself, the headline of the Select System type(s) dialog shows the information <Manual>.
Component selection:
Drop-down List
Specify if you would like to consider all components or only a certain part of the pipe duct for the calculation.
Detect partial network: The dialog is minimized and you can use the mouse to select the desired sub-network in the current view. You can select or deselect the corresponding components individually with a selection frame or with the mouse pointer. Confirm the selection of the components with Enter. The number of detected components is displayed in parentheses after doing the selection.
If you start the calculation after selecting Detect partial network, the program asks you to reconfirm the selected components for the partial network. You have the possibility to change the selection of the components again or to start the calculation with the currently selected partial network by pressing the Enter key. An error-free calculation is only possible if the selected partial network is self-contained.
Detect all visible components: Only the components currently visible in the model are detected for the pipe network calculation. If you select this option, an error-free calculation is only possible if the visible components form a closed pipe network.
: Allows to reselect a subnet in the current view. This button is only activated if you have selected the option Detect partial network and have already made a component selection.
: Selects the selected partial network in the current view. This button is only active if you have selected the option Detect partial network and have already made a component selection.
Overwrite Edited Pipe Lengths
If you adjust the length of pipe sections in the calculation dialog where pipe component lengths were previously adjusted manually, these adjusted pipe lengths can be retained or overwritten. By default, when adjusting such pipe sections, a corresponding query appears which can be disabled and which activates or deactivates the option Overwrite Edited Pipe Lengths. If this query is deactivated, the Overwrite Edited Pipe Lengths checkbox allows you to change the current setting.
Enabled: Edited lengths of pipe components in a pipe section are overwritten when the length of the section is changed. The change in the pipe section length is divided proportionally between the lengths of the individual pipe components.
Disabled: Edited lengths of pipe components in a pipe section are not overwritten when the length of the section is changed. TThe change in pipe section length is divided proportionally between the lengths of the pipe components without edited lengths.
Modeled Dimensions
You have the option to transfer the constructed dimensions from the model to the calculation for the entire network or for the selected partial network, or to have the program determine the required dimensions.
Drop-down list: Specify whether you would like to transfer the constructed dimensions from the entire model, from a partial network (apply for selection) or not at all to the calculation. If you select the option apply for selection, the dialog is minimized and you can individually select or deselect the corresponding components for which the modeled dimensions are to be applied to the calculation using a selection frame or the mouse pointer. For the remaining components, the program determines the dimensions in the calculation. If you do not transfer any constructed dimensions into the calculation, the required dimensions for the components are completely determined by the program.
: Allows to reselect components in the current view. This button is only activated if you have selected the option apply for selection and have already made a component selection.
: Selects the selected partial network in the current view. This button is only active if you have selected the option apply for selection and have already made a component selection.
Applying modeled dimensions in calculation
When you start the calculation, the program asks whether the modeled dimensions should be included in the calculation. If you have selected the option apply for selection in the Settings, only the dimensions for this selection will be applied to the calculation when you confirm the application.
Search radius
The search radius specifies the value up to which distances between components, which may have occurred during placement, are tolerated when calculating the network. This function prevents inaccuracies of component connections in the millimeter range from being recorded in the model as open ends and thus as errors during the calculation.
Room detection: Only detect rooms with mechanical ventilation
Enabled: Only mechanically ventilated rooms are included in the calculation of the air duct network.
Disabled: When calculating the air duct network, all rooms are included in the model. This can lead to a longer calculation time depending on the size of the model.
