[TRNSYS-users] TR: File handling

Wed Oct 5 06:10:55 PDT 2011

Dear Marcello,

It should work something like this:

Fid = getParameterValue(1)
Filename = getLUFilename(Fid)
Open(unit=Fid,file=Filename)
Read(Fid,*) value
Close(Fid)

Best regards,
Hermann.

Dear Hermann,

Thank you for your answer. However, the getLUfileName function gives me the name of the file as a string (which is, by the way, the correct one). But how can I use it to access this file?

Is there a form of the "read" instruction taking as parameter the file name instead of the unit number? If yes, could you give me an example of its use?

Thank you,

Marcello

Dear Marcello,

I think you have to use the getLUfileName function. See Programmers Guide page 7-46.

Best regards,
Hermann Schranzhofer.

Betreff: [TRNSYS-users] File handling

Dear TRNSYS users,

I would like to write a component for TRNSYS 17 which reads its parameters from an external file. In the proforma of my type, I specified a parameter "Logical unit", linked to the name of the file in the "File" tab.

In the FORTRAN code, at the iteration zero, my type simply use the read instruction as it follows:

unit_fichier_sortie = jfix(getParameterValue(4) + 0.1)

! Lecture de la version du fichier

read(unit_fichier_descriptif,*, iostat = erreur_lecture) par_1

However, instead of reading in the correct file, this instruction reads in a file called "fort.30" (where 30 is the logical unit number assigned by TRNSYS).

If I write my parameters in "fort.30", the type reads its parameters correctly. However, I would really like that it reads in the file I specify in the proforma ("exemple.in")!

If I debug the code, the function getLUfileName(unit_fichier_descriptif) returns the correct name of the file (example.in). 

Has someone experienced the same kind of problem? For information, I use Compaq Visual Fortran.

Thank you for your help!
