[TRNSYS-users] RE : Re: Equation use...

[Diego A. Arias]

Dear Guillaume,

Please go to Manual 7-"TRNEdit: Editing the input file and creating 
distributable applications", section 7.6.9 "The EQUATIONS Statement". It 
explains the available mathematical functions.

Sometimes it is easier to post-process the results in a spread sheet 
than to try to find the right combination of IF functions that will give 
you the result that you want.

Best regards,

Diego
