Camilo, Yes, you can do this; you will need to make some edits in the input file using TRNEdit. Before you start, make sure that your printing device (Type25 or Type46 ideally) has an output file that is called ***.out. The extension is not important but the *** is. Launch TRNEdit and open your input file . You should see a line that looks like the following: ASSIGN "c:\TrnsysXX\Weather\MyWeatherFile.tm2" 35 ASSIGN is a keyword that links the path and filename of the weather file to an arbitrary number called a "logical unit" You should also be able to find the entry for your weather file reader (Type15 or Type109 probably) in the input file; if you look at its list of parameters, you'll find one that has the value 35. It might look something like the following: UNIT 26 TYPE 15 Type15-6 PARAMETERS 9 6 ! 1 File Type 35 ! 2 Logical unit 3 ! 3 Tilted Surface Radiation Mode First, what you need to do is to make one ASSIGN statement for each of your weather files, assigning a DIFFERENT logical unit number to each one. For example: ASSIGN "c:\TrnsysXX\Weather\weatherFile(location1).tm2" 501 ASSIGN "c:\TrnsysXX\Weather\weatherFile(location2).tm2" 502 ASSIGN "c:\TrnsysXX\Weather\weatherFile(location3).tm2" 503 ASSIGN "c:\TrnsysXX\Weather\weatherFile(location4).tm2" 504 The value you assign is somewhat arbitrary but it must be greater than 30 and it cannot be used as the logical unit for anything else in your simulation. The range 501-550 is probably safe. Second, you need to add the following lines to your input file. CONSTANTS 1 LU_METEO = 501 Third, you need to change the entry of your weather reading component so that it contains a variable name instead of a numerical value for the logical unit. Taking the example from above, you would change it to read UNIT 26 TYPE 15 Type15-6 PARAMETERS 9 6 ! 1 File Type LU_METEO ! 2 Logical unit 3 ! 3 Tilted Surface Radiation Mode Lastly, make a parametric table (this is why you need to use TRNEdit). Select "Create New Table" from the parametrics menu item. Make 50 runs and choose the variable "LU_METEO" from the list on the left. Enter each of the values that you chose as the logical unit for your 50 weather files (501, 502, 503, etc.) Run the table. You should get 50 output files, one for each run. If you want all of the outputs in one file, then use Type25 as your output printer device, change the output file name from ***.out to Results.out (something with a hardcoded name) and change the 7th parameter (overwrite or append) from -1 to 1.
