<p>Michel,</p>
<p> This happens when TRNOpt/GenOpt picks some combination of
values that results in a simulation error. For instance, if you
were allowing TRNOpt to find a value of specific heat that best
fit some data but you did not prevent the guessed values of
specific heat from being negative then you might get this error.</p>
<p> The *.lst and *.log files (where the error is specified) will
be located in:</p>
<p> .\TrnsysXX\Optimization\GenOpt\Simulation\tmp-genopt-run-YYY</p>
<p>Either file can be opened with a text editor.</p>
<p>kind regards,</p>
<p> David</p>

<div>Hi all, <br>
</div>
<div><br>
</div>
<div>I am trying to do an optimization for my pv-hydrogen
system to find the optimal sizing.</div>
<div>I wanted to use the Parametric Mesh algorithm, however
TRNOPT terminates with the following error:</div>
<div><br>
</div>
<div><b>Optimization terminated with error.<br>
<br>
Error message:<br>
**************<br>
java.lang.ClassNotFoundException: <br>
genopt.algorithm.EquMesh<br>
Check whether file 'genopt.algorithm.EquMesh.class' is in
the correct path.<br>
<br>
GenOpt terminated with error.</b></div>
<div><br>
</div>
<div>Can you perhaps tell me where I have to look to find the
correct path?? The strange thing is that the Parametric
algorithm works just fine so it should be something with a
path issue but I can't manage to figure out where to look.</div>
<div><br>
</div>
<div>Any tip/help is appreciated.</div>
<div>Thanks.</div>
