      There is a limit of 999 surfaces in a TRNBuild model. I do not
    think that there is a limit to the number of surfaces that you can
    have in one zone; the limit is on the entire model. I had a project
    some time ago in which I had to combine a lot of windows together
    because there were so many individual windows that it sent my
    project over the limit. I believe that Transsolar is working on a
    solution to the problem.<br>
    Best,<br>

      <div>Hello TRNSYS users,</div>
      <div><br>
      </div>
      <div>Does someone can tell me if there is a limit number of
        windows in the TRNBUILD ZONES (based on a IDF created with the
        Sketchup plugin) in order to generate the shading matrix
        correctly?? I often have the error 41 "insufficient virtual
        memory" when I try to generate the shading matrix on TRNBUILD
        if I have a lot of windows in a project/zone (about 100 in  one
        zone for example), it is very annoying. If I delete multiple
        windows, the matrix is created but sometimes it's difficult to
        simplify the model.</div>
      <div><br>
      </div>
      <div>Thank you in advance.</div>
