Computational Engine Changes (epanet2.dll and epanet2d.exe):
===============================================================================
CODE MODULES CHANGES
===============================================================================
All All variables previously declared as floats were re-defined as
doubles except for those used to write results to binary output
files and those used as arguments in the toolkit functions.
EPANET.C Temporary files are now written to the users's current working
INPUT1.C directory or to the designated Temporary Directory when running
VARS.H the Windows GUI, thus avoiding file access problems for users
FUNCS.H who do not have administrative privileges on their machine.
-------------------------------------------------------------------------------
EPANET.C The symbols CLE (for command line executable) and SOL (for shared
object library) were introduced in addition to the existing
symbol DLL (for dynamic linked library) to support conditional
compliation for shared object libraries on Unix/Linux.
EPANET.C The following tank parameters were made available for retrieval
TOOLKIT.H using the Toolkit's ENgetnodevalue function: tank diameter,
EPANET2.H minimum volume, index of the tank's volume curve, the initial,
minimum, and maximum water levels, the fraction of a 2-compart-
ment tank devoted to the mixing zone, and the tank's bulk
reaction rate coefficient. These same parameters (with the
exception of the volume curve) were made modifiable using the
ENsetnodevalue function, as was the choice of mixing model.
See the Toolkit Help file for details.
-------------------------------------------------------------------------------
EPANET.C EN_INITVOLUME, EN_MIXMODEL and EN_MIXZONEVOL were added to the
EPANET2.H list of tank parameters that can be retrieved with
TOOLKIT.H ENgetnodevalue.
EPANET.C A new Toolkit function, ENaddpattern, was added that allows
TOOLKIT.C programmers to add a new time pattern to the network in any
EPANET2.H custom code that they write.
-------------------------------------------------------------------------------
EPANET.C Missing code was added to the ENgetnodevalue function to return
a value for EN_SOURCEPAT when requested.
HYDRAUL.C A DAMPLIMIT parameter was added to control at what point during
INPUT1.C the hydraulic solution iterations status checks on PRVs and PSVs
INPUT3.C begin and subsequent flow changes are dampened.
REPORT.C
VARS.H
TEXT.H
-------------------------------------------------------------------------------
EPANET.H The function declarations in these "include" files were modified
TOOLKIT.H to support conditional compliation for shared object libraries
on Unix/Linux.
HYDRAUL.C Demands for tanks (net inflows/outflows) were not always being
set to zero when the tank was full or empty which was causing
problems in the water quality routing solutions.
-------------------------------------------------------------------------------
INPUT3.C The keyword "HEADLOSS" is no longer confused with "HEAD" when
parsing reporting variable names in the [REPORT] section of the
input file.
QUALITY.C The water quality functions for all of the tank mixing models
were modified so as to produce more robust results for cases
where there is a significant amount of volume exchange over a
water quality time step.
-------------------------------------------------------------------------------
RULES.C The input values for a tank's FILLTIME or DRAINTIME in a rule
premise are now correctly converted to seconds in the
newpremise() function.
EPANET.C A problem with the system not recognizing that water quality
QUALITY.C reactions could begin after some initial period of time when
VARS.H the Toolkit was used to modify reaction rate coefficients was
fixed.
-------------------------------------------------------------------------------
HYDRAUL.C During hydraulic balancing, status checks on control valves are
now made only when the convergence error drops to less than a
factor of 10 of the accuracy limit and a damping factor of 0.6
is applied to flow changes computed at each iteration beyond
this point.
INPFILE.C A problem with extraneous lines being written to the [REPORT]
section of an EPANET input file created with the ENsaveinpfile
function was fixed. Also the number of decimal places for some
items written to the saved file, such as nodal demands, was
increased.
-------------------------------------------------------------------------------
HYDRAUL.C The logic for determining the status of PRVs and PSVs was changed
to produce more robust solutions, particularly for the case of
multi-stage regulator stations where there are two or more PRVs
connected in parallel.
-------------------------------------------------------------------------------
HYDRAUL.C The matrix coefficients for fully open control valves are now set
directly rather than by assuming the valve has a certain length
and friction factor.
-------------------------------------------------------------------------------
HYDRAUL.C Changes were made to how the P-coefficient for FCVs and the Y-
coefficient for GPVs are calculated.
-------------------------------------------------------------------------------
HYDRAUL.C An extraneous "if" statement was removed from the resistance()
function; the Y-coefficient value in gpvcoeff() was corrected;
the P-coefficient value in fcvcoeff() was corrected.
-------------------------------------------------------------------------------
QUALITY.C The memory pool used for water quality routing segments was given
the name SegPool and declared as a static global variable.
-------------------------------------------------------------------------------
QUALITY.C In the release() function, the upstream node quality is now mixed
together with that of the upstream pipe segment when the quality
difference between the two is less than the CTOL tolerance.
-------------------------------------------------------------------------------
INPFILE.C The ENsaveinpfile toolkit function now writes disabled reporting
variables to the [REPORT] section of the generated input file.
-------------------------------------------------------------------------------
INPFILE.C The appearance of an extraneous character at the end of the .INP
file produced by the toolkit function ENsaveinpfile was fixed.
-------------------------------------------------------------------------------
TYPES.H MAXID was increased to allow ID names to contain up to 31
HASH.C characters.
-------------------------------------------------------------------------------
TYPES.H The code version was changed to 20011.
TYPES.H The code version was changed to 20012 and INT4 was explicitly
defined as an "int" data type.
