Description:

Step 1a.6 - Hangs at attaching heads

Solutions:

Cause:

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!

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.

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) select the System Walker and 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.

Cause:

Water source is on a flange.

Solution:

Change flange to cap.

Cause:

All piping is defined as Lines

Solution:

Define a pipe as a main, or ad a main to the Model.

Cause:

Incorrect pipe type used for flexible sprinkler connection.

Solution:

Change sch 40 to sch 30, by loading defaults

Cause:

In an effort to be more efficient, trying to run calculations from two different Revit models at the same time causing confusion and corruption of temporary files.

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.

Solutions:

1.- Cause: 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.
