The "CLOSE error" suggests that there is a problem closing the file, which is a bit strange; normally file errors occur when trying to open files (because the file isn't where it is supposed to be). You may be correct that the problem has to do with read/write permissions. Do you have a Fortran compiler? If so, you can run the project from within your Fortran compiler and stop on the line that is causing the error. I am afraid that I do not have a copy of Fluent and so cannot debug it for you.<br>Kind regards,<br> David<br><br><br>On 7/7/2011 04:32, Baboo Gowreesunker wrote: <o:p></o:p></p><p class=MsoNormal>Hi all<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I’m running type 101 on a windows 7, 64 bit machine. <o:p></o:p></p><p class=MsoNormal>Everytime I run the simulation, it runs for a few time steps, and then I obtain the following error:<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Forrtl: severe (28): CLOSE error, Unit 10, file “Unknown” Image PC Routine Line Source libifcoremd.dll 03DBD3FE Unknown Unknown Unknown<o:p></o:p></p><p class=MsoNormal>Stack trace terminated abnormally.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>I don’t believe its an error in the code because otherwise it would not run the few timesteps.<o:p></o:p></p><p class=MsoNormal>I don’t know whether it has to do with ‘limited access to C: drive’, where libifcoremd.dll is located.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Can somebody help me ?<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='color:#17365D'> </span><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><pre><o:p> </o:p></pre><pre><o:p> </o:p></pre><pre>_______________________________________________<o:p></o:p></pre><pre>TRNSYS-users mailing list<o:p></o:p></pre><pre><a href="mailto:TRNSYS-users@cae.wisc.edu">TRNSYS-users@cae.wisc.edu</a><o:p></o:p></pre><pre><a href="https://mailman.cae.wisc.edu/listinfo/trnsys-users">https://mailman.cae.wisc.edu/listinfo/trnsys-users</a><o:p></o:p></pre><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br><br><o:p></o:p></span></p><pre>-- <o:p></o:p></pre><pre>***************************<o:p></o:p></pre><pre>David BRADLEY<o:p></o:p></pre><pre>Principal<o:p></o:p></pre><pre>Thermal Energy Systems Specialists, LLC<o:p></o:p></pre><pre>22 North Carroll Street - suite 370<o:p></o:p></pre><pre>Madison, WI 53703 USA<o:p></o:p></pre><pre><o:p> </o:p></pre><pre>P:+1.608.274.2577<o:p></o:p></pre><pre>F:+1.608.278.1475<o:p></o:p></pre><pre><a href="mailto:d.bradley@tess-inc.com">d.bradley@tess-inc.com</a><o:p></o:p></pre><pre><o:p> </o:p></pre><pre><a href="http://www.tess-inc.com">http://www.tess-inc.com</a><o:p></o:p></pre><pre><a href="http://www.trnsys.com">http://www.trnsys.com</a><o:p></o:p></pre></div></body></html>
