Hi, I am now doing the post processing of the intake/exhaust strokes of a engine(model setup with star and es-ice),and in order to better understand the case, I am planning to obtain the value of a certain scalar at every iteration,using "ofile casename.dat" and a loop. I thought the casename would change with different iteration but in fact the integer that I set was recognized as a string of characters and never changed. How can I generate .dat files with names corresponding to the iterations in a loop? Thanks in advance!

Why don't you use the 'Monitor Engineering Behaviour' function?

Have you looked at the string variables (*SSET)? I think it should go something like this: *SSET CHAR5 casename $ ofile {CHAR5}.dat. I remember using this a few years ago. Haven't tried it since.

I tried that,setting "casename" as an integer changing with loops,but it seems that "casename" was only regarded as a string instead of a integer,because only a "casename.dat" was generated finally,integers not involved.

Thanks!I am going to have a try!

you could try to convert a number into a string by using command
<code>*scopy</code>
try in prostar output window
<code>help *scopy</code>
might help, but not sure.

Try:

*set count 0,x,1 (where x is number of cases) => *scopy,count,case_nr,(I0) => *set tmp case{case_nr}
