Re: Output Precision



Dear Juan

Have I also noticed that it somehow disappeared from the TRNSYS manual? Please find two examples of printer units definitions with format statement below (TRNSYS 14.2). Note that the statement covers the time column too. I believe that the possibility to specify the output format still persist with TRNSYS 15 (it does with 14.2). Hope this helps.

Dear TRNSYS Users,

 

I would like to know if it is possible to increase TRNSYS outputs precision without recompiling trnlib.dll. I am undertaking numerical optimization with GenOpt 2.0 and a greater number of digits makes it a bit easier for the optimization algorithm, as it appears.

 

Thanks in advance,

Juan Pablo de Lima Costa Salazar
