Pipe Manager Issues (known issues)
No backwards compatibility between iDAS 12 and older versions (10 or 11)
Any pipe networks which are opened in iDAS 12 Pipe Manager cannot be opened in Devotech iDAS 10 or 11 (Storm, Sewer and Water managers), because there is no backwards compatibility. We had to improve the mapping functionality and we could not make it backwards compatible.
Surfaces are not displayed in the Pipe Manager
The surfaces were removed to improve Pipe Manager performance.
Import INP generated by iDAS to SSA does not import Surcharge Depth
If you import an INP file generated by iDAS to SSA (Autodesk Storm and Sanitary Analysis), it might not import the Surcharge Depth. This is an SSA bug. To avoid this issue, open any existing SSA file (file with SPF extension) and then import the INP file again. It seems that when any SPF file is opened (it can even be an empty file) it forces SSA to load all the components correctly and importing the INP file works as it should.
Import library objects always adds number 1 at the end of the name
This behavior changes the name of the imported object, e.g. Pattern, Curve, Hydrograph etc., therefore it does not match with the description. This behavior is intentional to avoid issues with the duplicate names.
Cannot set time series for direct inflow
Direct inflow is used for the inflow from catchments when the Rational Method is used. The EPASWMM engine does not allow to specify multiple direct inflows with various time series, therefore we could not implement the time series for the direct inflow.
Curve type is not correctly imported to EPANET
When importing INP file to EPANET v 2.00.12 and newer, the curve type is not correct, all the curves have PUMP as type. This is an EPANET bug. EPANET v 2.00.10 works as expected.
Ovoid (egg shape) pipes cannot be analyzed
Pipe mapping offers to map egg shape pipes to a pipe style but the pipes do not appear under conduits in the pipe manager.
Water controls limitations
The pipe and structure cannot be named with any of the following names: "Node", "Link", "If", "Below", "Above", "Closed", "Time", "At", "Open", and any number (integer or decimal) e.g.: 1.123, 2, 4 etc.
If you rename pipe or structure used in the controls, the controls do not update automatically, you must manually reassign pipes and structures in the controls.
Pipe and structure names
The pipe and structure names cannot contain any of the following words: "Node", "Link", "If", "Below", "Above", "Closed", "Time", "At", "Open", e.g.:
- Node, Node1, Node 1, Node1.1 etc.
- Link, Link1, Link 1, Link 1.1 etc.
Renaming pipe and structures used in water controls
If you rename pipe or structure used in the water controls, the water controls do not update automatically, you must manually reassign pipes and structures in the water controls, otherwise, they will use the old name.
Two surface channels connected to one inlet structure
Two surface channels cannot be connected to a single inlet structure, otherwise, a "ctor" error will occur.
Water pump speed multiplier is not used
If you use pump speed multiplier then it is not used in the analysis. However, if you take the INP file generated by iDAS during the analysis and import it into EPANET, the speed multiplier will be used as expected.
iDAS uses the EPANET DLL for the analysis which has this limitation. The EPANET standalone program does not have this limitation.
If you use a pattern to override the speed multiplier, then the correct value is used (use 1 for Speed Multiplier and use the desired values in the pattern):
Pattern definition in the Library tab, Patterns sub-tab:
BOM structure summary tab empty
If a depth group contains duplicate depth category values then the Excavation – Structure Summary table will not be populated with the excavation results.
Duplicate depth category values:
Empty table:
Removing networks from profile views does not remove labels
When removing networks from profile views with the Profile View - Clean Up command, then the labels will remain in the profile view:
Before pipe removal:
After pipe removal (note the labels remaining in the profile view):
This is a Civil 3D bug and this issue also occurs if the Draw check box is unchecked in the in the Profile View Properties window:
If you delete the parts directly from the profile view in the model space, then the Draw check box is also unchecked in the Profile View Properties window, and it also deletes the labels.
Water Valves and pumps connected to top tanks cause the analysis to fail with error number 215
When a tank's Inlet Position is set to Top, and a pump or valve is connected to the tank, then the analysis fails with Input Error 215
If a pump or valve is connected to the tank, then the error can be resolved by inserting a new structure before the tank and connecting the pump or valve to that structure.
If a pressure sustaining valve (PSV) is connected to the tank, then the error can be resolved by swapping the PSV for a junction. When setting the Inlet Position of the tank to Top a PSV is introduced by the analytical engine with a pressure of zero. Therefore, connecting an additional PSV to the tank is unnecessary.
