 \subsubsection{How do I access model time during the simulation?}
 The variable \code{t} in the evolve for loop is the model time.
+For example to change the boundary at a particular time (instead of basing this on the state of the system as in Section \ref{sec:change boundary}) 
+one would write something like
 {\small \begin{verbatim}
-    for t in domain.evolve(yieldstep = 0.1, duration = 4.0):
-        if t > 15:
-            <Do something>
+    for t in domain.evolve(yieldstep = 0.2, duration = 40.0):
+        
+        if Numeric.allclose(t, 15):
+            print 'Changing boundary to outflow'
+            domain.set_boundary({'right': Bo})      
+            
 \end{verbatim}}
 The model time can also be accessed through the public interface \code{domain.get\_time()}, or changed (at your own peril) through \code{domain.set\_time()}.
