Description:

Step 1a.6 - Hangs at attaching heads

Solutions:

1.
Cause:

Bad supply point. 

The Supply Point feature was somehow misused, abused or corrupted.  It is worth remembering that the Suppy Point must be assigned to a fitting ( not a pipe, not a pipe accessory (valve or device), not Mechanical Equipment ( a pump) and not a Sprinkler.  Also, if you delete the fitting used as a Supply Point, you will need to reinsert the Supply Point.
Solution:

Simply:

  • Cancel the Hung Calculation
  • reinsert the Supply Point:  HydraCALC...  Supply Point...  Pick on a fitting.
  • Restart the Calculation

    Important Tip:   When selecting a fitting, make sure that it is highlighted when you pick it so that the Supply Point is actually associated with that fitting!
2.
Cause:

Flexible piping connection attached to a pipe end.
Solution:

Flexible piping connections must be attached to a fitting of some kind such as a coupling, elbow, tee, or cross. Relocate it from a pipe end to one of these.
3.
Cause:

There is not a continuous path of connected pipes from the sprinklers to the source, possibly due to using a system divider somewhere else in the project. 
Solution:

From any of the Hydratec for Revit ribbons (HydraCAD, HydraCALC, HydraLIST)...

  1. Select the System Walker
  2. Make sure all of the pipes in your project are selected up to the Supply Point.

You might need to check multiple views in order to make sure it was included. If there isn't a continuous path, make changes to the model to ensure there is. Some of the changes you might need to make include....

  1. Remove any System Dividers breaking up the run of pipe
  2. Connect any unconnected pipe
4.
Cause:

Water source is on a flange.
Solution:

Change flange to cap.
5.
Cause:

All piping is defined as Lines
Solution:

Define a pipe as a main, or add a main to the Model.
6.
Cause:

Incorrect pipe type used for flexible sprinkler connection.

Solution:

Change Sch 40 to Sch 30, by loading defaults
7.
Cause:

Don't run 2 calculations at the same time.

Trying to run two calculations from two different Revit models at the same time is causing important files to misbehave, or become corrupted.
Solution:

Don't try to run calculations from two different Revit models at the same time. The files MaximumPipeSizes-Default.dat and MaximumPipeSizes.dat which are located in the :\HES\Hydratec for Revit\Data\Setup folder need to be replaced. These files can be copied from another computer, if there is no other computer, they can be obtained from Hydratec.
