Hi Nek,<br> I just have met some trouble in generating mesh file with genbox tool. When the genbox reading the .box file, the error says 'fortran runtime error: end of file' occured. I had a relatively complicated computational domain so I divided it into 14 boxes. I wonder if the number of boxes is too large that genbox cannot deal with them. Before that I tried 8-box case and it ran well. Thanks for any help.<br> kind regards,<br> Xu B.L.<br><br><br><span>--<br>Xu Bolun,<br>University of Science and Techonology of China,<br>Hefei,Anhui,China<br></span>
