Dear Younness, Is there any indication as to which file TRNSYS thinks does not exist? When you run a parametric table with N rows in it any output file that has the same name as the input file (but obviously a different file extension) will get automatically recreated N times with the run-number appended to the end of the file name. For example, if your input file produces an output file called CONFIG.xls and you run a parametric table that has 3 runs, you will get three output files: CONFIG1.xls, CONFIG2.xls, and CONFIG3.xls. If your input file is looking for some performance data that has the same name as the input file, it might be looking for a performance file that has the run number appended. That is just a guess! If you can't solve the problem, please send the *.dck to your distributor for assistance.
