The configuration you are</div><div class="">simulating does not seem to be very complex, hence a longer</div><div class="">simulation is not expected to be very time consuming.</div><div class=""><br class=""></div><div class="">Finally, I you want, you can your macros directly to me and</div><div class="">allow me to check for potential problems.</div><div class=""><br class=""></div><div class="">Kind regards and best wishes,</div><div class=""><br class=""></div><div class="">U.
