Release Notes for EPANET 2.2 (Draft)
Release Notes for EPANET 2.2 (Draft)
============================
This document describes the changes and updates that have been made to version 2.2 of EPANET.
## Thread-Safe API Functions
A duplicate set of the version 2.1 API functions has been provided that allow multiple EPANET projects to be analyzed concurrently in a thread-safe manner. These functions maintain the same name as the original but use a `EN_` prefix instead of `EN`. In addition, the first argument to each of these functions is a handle that identifies the network data for the particular project being analyzed. For example, instead of writing:

Two new functions have been added to the API to manage the creation and deletion of project handles. `EN_createproject` creates a new project along with its handle, while `EN_deleteproject` deletes a project. An example of using the thread-safe version of the API is shown below:
```
#include "epanet2.h"
#include "epanet2_2.h"
int runEpanet(char *finp, char *frpt)
{
EN_ProjectHandle ph = 0;

if (err) return err;

Prototypes of the thread-safe functions appear in the `epanet2_2.h` header file while `epanet2.h` contains prototypes of the legacy-style API functions. The enumerated constants used with both types of functions have been moved to `epanet2_enums.h`.
## Network Building By Code
API users now have the ability to build a complete EPANET network model using just function calls, without the need to open an EPANET-formatted input file. All types of network objects can be created and have their properties set using these calls, including both simple and rule-based controls. Here is an example of building a simple 2-node, 1-pipe network just through code:
```
#include "epanet2_2.h"
int buildandrunEpanet(char *frpt)
{
EN_Project ph = 0;
int err;
err = EN_createproject(&ph);
if (err) return err;
EN_init(ph, frpt, "", EN_GPM, EN_HW);
EN_addnode(ph, "J1, EN_JUNCTION);
EN_setjuncdata(ph, 1, 710, 500, ""); //elev, demand
EN_addnode(ph, "R1", EN_RESERVOIR);
EN_setnodevalue(ph, 2, EN_ELEVATION, 800);
EN_addlink(ph, "P1", EN_PIPE, "R1", "J1");
EN_setpipedata(ph, 1, 5280, 14, 100, 0); // length, diam, C-factor
EN_setreport(ph, "NODES ALL");
err = EN_solveH(ph);
if (!err) err = EN_report(ph);
EN_close(ph);
EN_deleteproject(&ph);
return err;
}
```
Instead of using `EN_open` to load data from a file, `EN_init` is used to initialize a project with the names of its report and binary files, and its flow units and head loss formula. The legacy-style API has a complementary set of functions for building networks from code.
## Additional Convergence Parameters
@@ -44,16 +72,19 @@ Two new analysis options have been added to provide more rigorous convergence cr
These new parameters augment the current `EN_ACCURACY` option which always remains in effect. In addition, both `EN_HEADERROR` and `EN_FLOWCHANGE` can be used as parameters in the `ENgetstatistic` (or `EN_getstatistic`) function to retrieve their computed values (even when their option values are 0) after a hydraulic solution has been completed.
## Improved Linear Solver Routine
EPANET's hydraulic solver requires solving a system of linear equations over a series of iterations until a set of convergence criteria are met. The coefficient matrix of this linear system is square and symmetric. It has a row for each network node and a non-zero off-diagonal coefficient for each link. The numerical effort needed to solve the linear system can be reduced if the nodes are re-ordered so that the non-zero coefficients cluster more tightly around the diagonal.
EPANET's original node re-ordering scheme has been replaced by the more powerful **Multiple Minimum Degree (MMD)** algorithm. On a series of eight networks ranging in size from 7,700 to 100,000 nodes **MMD** reduced the solution time for a single period (steady state) hydraulic analysis by an average of 58%.
## Improved Handling of Near-Zero Flows
EPANET's hydraulic solver can generate an ill-conditioned solution matrix when pipe flows approach zero unless some adjustment is made (i.e., as a pipe's flow approaches 0 its head loss gradient also approaches 0 causing its reciprocal, which is used to form the solution matrix's coefficients, to approach infinity). EPANET 2.0 used an arbitrary cutoff on head loss gradient to prevent it from becoming 0. This approach doesn't allow a pipe to follow any head loss v. flow relation in the region below the cutoff and can produce incorrect solutions for some networks (see [Estrada et al., 2009](https://ascelibrary.org/doi/full/10.1061/%28ASCE%29IR.1943-4774.0000100)).
The hydraulic solver has been modified to use a linear head loss v. flow relation for flows approaching zero. For the Darcy-Weisbach equation, the linear Hagen-Poiseuille formula is used for laminar flow where the Reynolds Number is <= 2000. For the Hazen-Williams and Chezy-Manning equations, a flow limit `Qa` is established for each pipe, equal to the flow that produces the EPANET 2 gradient cutoff. For flows below this a linear head loss relation is used between 0 and the head loss at `Qa` and the gradient always equals the cutoff. EPANET 2.2 is now able to correctly solve the examples presented in Estrada et al. (2009) as well as those in [Gorev et al., (2013)](https://ascelibrary.org/doi/10.1061/%28ASCE%29HY.1943-7900.0000694) and [Elhay and Simpson (2011)](https://ascelibrary.org/doi/10.1061/%28ASCE%29HY.1943-7900.0000411).
## Pressure Dependent Demands
EPANET has always employed a Demand Driven Analysis (**DDA**) when modeling network hydraulics. Under this approach nodal demands at a given point in time are fixed values that must be delivered no matter what nodal heads and link flows are produced by a hydraulic solution. This can result in situations where required demands are satisfied at nodes that have negative pressures - a physical impossibility.
To address this issue EPANET has been extended to use a Pressure Driven Analysis (**PDA**) if so desired. Under **PDA**, the demand *D* delivered at a node depends on the node's available pressure *P* according to:

## Improved Water Quality Mass Balance
As described by [Davis et al. (2018)](https://www.drink-water-eng-sci.net/11/25/2018/dwes-11-25-2018.pdf) EPANET's water quality simulations can result in some significant mass balance errors when modeling short term mass injections (errors are much smaller for continuous source flows). The entire water quality engine has been re-written to eliminate these errors. It still uses the Lagrangian Time Driven transport method but now analyzes each network node in topologically sorted order rather than in arbitrary order.
A Mass Balance Report now appears the end of a simulation's Status Report that lists the various components (inflow, outflow, reaction) that comprise the network's overall mass balance. In addition `EN_MASSBALANCE` can be used as a parameter in the `ENgetstatistic` (or `EN_getstatistic`) function to retrieve the Mass Balance Ratio (Total Outflow Mass / Total Inflow Mass) at any point during a water quality simulation.

## Code Changes
- The header file `vars.h` containing global variables has been eliminated. Instead a number of new structures incorporating these variables has been added to `types.h`. These structures have been incorporated into the new `EN_Project` structure, also defined in `types.h`, which gets passed into each of the thread-safe API functions as a pointer.
- Each of the legacy API functions now simply calls its thread-safe counterpart passing in a pointer to a default global`EN_Project` variable that is declared in `types.h`.
- Throughout all code modules, global variables that were previously accessed through `vars.h` are now accessed using the `EN_Project` pointer that is passed into the functions where the variables appear.
- The exceedingly long `hydraul.c` file has been split into four separate files:
- `hydraul.c` now contains just the code needed to initialize a hydraulic analysis, set demands and control actions at each time step, and determine the length of the next time step to take.
- `hydsolver.c` implements EPANET's hydraulic solver at a single point in time.
- `hydcoeffs.c` computes values of the matrix coefficients (derived from link head losses and their gradients) used by the hydraulic solver.
- `hydstatus.c` checks for status changes in valves and pumps as requested by the hydraulic solver.
- The Multiple Minimum Degree re-ordering algorithm appears in a new file named `genmmd.c`. This is 1990's legacy code that is readily available on the web and can be found in several linear equation solver libraries.
- The original `quality.c` file has also been split into three separate files:
- `quality.c` initializes the quality solver and supervises the quality calculations over each simulation time step.
- `qualreact.c` reacts the quality constituent within each pipe and tank over a single time step and also implements the various tank mixing models.
- `qualroute.c` topologically sorts the network's nodes when flow directions change and implements the Lagrangian Time Driven transport algorithm over a single time step.
