    Wang,<br>

     TRNBuild calculates the coefficients of a transfer function that

    describes the way in which energy is transferred through a given

    wall. The transfer function is basically an infinite series and each

    coefficient is a multiplier on a particular term in the transfer

    function (an example of one of the terms is the temperature

    difference across the wall). Time is discretized into steps

    backwards through the wall's history; the step size is called the

    time base. For example, if the time base is 1 hour then coefficient

    multipliers for each term in the transfer function will be computed

    for now, 1 hour ago, 2 hours ago, 3 hours ago etc.<br>

    Regards,<br>

              Subject: Re: [TRNSYS-users] GenOpt optimization: problem

              for the secondgeneration after 5 simulations<br>

              This type of error in GenOpt is usually caused by an error

              in the TRNSYS<br>

              simulation.  You need to check the *.lst file for the

              TRNSYS run to see<br>

              what the TRNSYS error is.<br>

              <br>

              Regards,<br>

                 Dear Alexis,<br>

              <br>

                 I've had a similar error when I used Genopt. I've had

              several<br>

                 components tracked by a "trace" command that made my

              list file<br>

                 enormous (more than 100Mb) and genopt could'nt handle

              that amount of<br>

                 data.<br>

              <br>

                 Just my 2cents.<br>
