Pipework – Terminate
With a load object

Example

Pipes for drinking water and drainage can be terminated with a load object.ClosedMore

Suppose you design a pipe network for a large building. For the coordination between the technical disciplines, you usually start with the main pipes and risers. To reserve the space requirements, you need to roughly calculate the dimensions. With a load you can represent a subnetwork and simulate the load conditions for calculating the main pipes.

Workflow

  1. Move the pipe to the position where you want to terminate it using the object.
  2. Define a fix point by clicking .
  3. Select: End with load object
    The dialog appears: Load object domestic water

  4. Check the settings. Pay special attention to:

    Select the medium from the product database. Click on .

    Total calculated flow rate of the sub network.

    Permanent flow rate at the connection point of the sub network.

    Pressure loss within the sub network.

    Setting for the behaviour of the object in the event that the height of the selected reference in the building model changes. ClosedExample

    Setting Effect

    DDScad calculates a new value for Distance. The object ignores the change of the building model.

    DDScad checks changes in the height ratio between the object and the selected reference using the function Check and Verify Models.ClosedWorkflow
  5. Click OK. The pipe terminates with the object. The function remains active. You can set the next starting point.
  1. Move the pipe to the position where you want to terminate it using the object.
  2. Define a fix point by clicking .
  3. Click . The context menu appears.
  4. Select: End with load object
    The dialog appears: Load object waste water

  5. Check the settings. Pay special attention to:

    Sum of the connection values of all connected objects.

    Biggest discharge unit value among the connecting objects.

    Sum of all continuous outflows (e.g. cooling water).

    Type of simulated pipe line for the calculation of the wastewater network.

    Setting Description

    Branch Discharge Pipe Single

    Branch Discharge Pipe Multi

    Stack

    Drain Multi

    Drain

    Stack Vent Single

    Stack Vent Multi

    Ventilating Stack

    Length of the symbols. You can use different unit of lengths.

    Setting about the behavior of the connected pipeline in the pipe network calculation.

    This option exists only if the pipeline has been terminated using this method:ClosedEnd with load object

    Setting Effect

    Definition of a nominal diameter in Connection DN/OD. After a pipe network calculation, the connected pipeline takes over the selected nominal diameter.

    Use this option if the load object simulates an object with a single branch discharge pipe.

    The nominal diameter of the connected line is dimensioned below by the pipe network calculation according to the entered values below System data.

    Use this option if the load object simulates a subnetwork.

    Distance between the selected reference and the centre axis of the object.

    In the case of settings Free and User 1 - … User 4 - you can enter the mounting height as a number with the desired length unit.

    The sign of the value entered determines the direction in which it takes effect.

    Value >0 Installation above the selected reference.
    Value <0 Installation below the selected reference.
    Value =0 Installation at the height of the selected reference.
  6. Click OK. The pipe terminates with the object. The function remains active. You can set the next starting point.
