Details on “Component Detection” in the “Settings” (Heating/Cooling)
Information about the Component Detection section in the Settings dialog for Pipe Network Calculation Heating and cooling.
In this area, you can define global settings for detecting components, pipes, and ducts that are used in the calculation. You can also specify whether the dimensions constructed in the drawing are used in the calculation or whether the required dimensions are determined. You can adjust the search radius for detecting connected components and specify how manually adjusted pipe lengths are handled when the length of the associated section is changed. The settings are saved with the project.
You are here:
Component Selection
Use this drop-down list to specify whether you want to include all components or only a specific part of the pipe network in the calculation. The list contains the following options for component selection:
-
Detect all components: The entire pipe network with all components is detected and taken into account during calculation.
-
Detect Partial Network: If you select the Detect partial network option, the dialog is minimized and you can select the desired partial network in the current view. You can select or deselect the corresponding components with a selection frame or individually. Confirm the selection of the components with Enter. The number of detected components is displayed in brackets after Detect partial network.
Calculate Partial Networks
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.
: 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 activated if you have selected the option Detect Partial Network and have already made a component selection.
Modeled Dimensions (Heating)
You have the option of transferring the designed dimensions from the drawing to the calculation for the entire network or for a selected partial network, or you can have the program determine the required dimensions. The drop-down list contains the following options for transferring modeled dimensions:
- Do Not Apply: The modeled dimensions are not included in the calculation, and the program determines the dimensions of all components during the calculation.
- Apply: The modeled dimensions are used in the calculation.
- Apply for Selection: If you select the option Apply for Selection, the dialog is minimized and you can select or deselect the corresponding components for which the modeled dimensions are to be included in the calculation using a selection box or the mouse. For the remaining components, the program determines the dimensions in the calculation.
Take Selection into Account in Calculation
If you start the calculation after selecting Apply for Selection, the program will ask you to reconfirm the selected components for the partial network. You have the option of changing the selection of components again or starting the calculation with the currently selected partial network by pressing Enter.
: 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 enabled if you have selected the option Apply for Selection 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 disabled, you can change the current setting using the checkbox Overwrite Edited Pipe Lengths.
Activated: 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.
Search Radius
The search radius specifies the maximum distance between components that may have been created during drawing and that is tolerated in the calculation of the network. This function prevents inaccuracies in the drawing of component connections in the millimeter range from being detected as open ends and thus as errors during calculation.
