Hi I am trying to do a simulation of the combined solar tower system system using TRNSYS 16with STEC library, which contains a heliostas field encountered the following error from GenOpt. Unable to read data from an external file that has been ASSIGNed in the TRNSYS input file. I assume there is something to do with the external files that associated with this type , but I have no clue how to fix it. Many thanks! Regards, |
