<p class="MsoNormal"><span><span style="font-family:Arial;color:black" lang="EN-US">I have some questions about <span>TRNFlow</span> and
Calling Matlab.</span></span></p>

<p class="MsoNormal"><span><span style="font-family:Arial;color:black" lang="EN-US">1) <span>For</span> <span>Closed</span> <span>Opening</span> in <span>TRNFlow</span>: There
is a flow coefficient <span>Cs</span> per m crack length, the default value is 0.0001 kg/s/m at 1 Pa. Why is it this value? How to get or calculate it?<span style="color:rgb(51, 102, 255)"> <span style="color:rgb(0, 0, 0)">Since I don't know how many meters of the cracks are in the zone.</span>  I seeked from the TRNFlow manual but there is nothing about it.</span><br>

flow escaping from the zone (there is only one zone in my project). Because I
observed CO2 concentration is still decreasing all the time after <span>closed</span> all
the openings. <br></span></span></p><p class="MsoNormal"><br><span><span style="font-family:Arial;color:black" lang="EN-US"></span></span></p><p class="MsoNormal"><span><span style="font-family:Arial;color:black" lang="EN-US">If
 I want to simulate the infiltration rate (0.4 1/h) after closing all 
the openings, How could I set this Cs? What equations can I use? </span></span><span><span style="font-family:Arial;color:black" lang="EN-US">Many thanks in advance!</span></span></p>

<p class="MsoNormal"><span><span style="font-family:Arial;color:black" lang="EN-US">2) <span>For</span> Calling Simulink: Which experts
have some experience <span>for</span> calling Simulink? I designed a Controller using
Simulink, I need connect the controller’s output and input with the TYPE 56’s input and output, and set a set-point
value using Simulink. Who could tell me some general guides or pass me your examples
about that. I will appreciate very much for your help! Since I also didn't find anything in Manual or others.<br></span></span></p>

<p class="MsoNormal"><span><span style="font-family:Arial;color:black" lang="EN-US">Or must I translate Simulink into M-file,
then connect with TYPE 56?</span></span></p>
