ENrunQ.m

function [errcode, t] = ENrunQ()
% Declaration:
% [errcode,t] = ENrunQ( void )
% 
% Description:
%  Advances the water quality simulation to the start of the next hydraulic
%  time period.  
% 
%Arguments: 
% 
% Returns:
%  Returns an error code.
% 
%Notes:
%  This function is used in a do-while loop with ENrunQ to perform an 
%  extended period water quality analysis. It allows you to access water
%  quality results at each hydraulic period of the simulation. The water 
%  quality routing and reactions are carried out internally at a much 
%  smaller time step. Use ENstepQ instead of this function if you need 
%  to access results after each water quality time step.  
%
%  The value of tstep is determined from information saved with the 
%  hydraulic analysis that preceded the water quality analysis. 
%  Treat it as a read-only variable.  
%
%Example: 
%   long t, tstep;  
%   ENsolveH(); /* Generate & save hydraulics */  
%   ENopenQ();  
%   ENinitQ(0);  
%    do {  
%      ENrunQ(&t);  
%      /* Monitor results at time t, which   */  
%      /* begins a new hydraulic time period */  
%      ENnextQ(&tstep);  
%   } while (tstep > 0);  
%    ENcloseQ();
