Yes, there is a 2GB border. That belongs to StarCD. The next boarder is the 4GB, which belongs to the 32bit OS. I think in general it is not recommanded to use such big files. Is the file corrupt for any reason, all results are distroyed.

I suppose that the this problem arise with transient calculations. The remedy is to use a backup frequency. So you can write out each time step in its own *.pst file. with a loop you can load each *.pst_xxxx file step by step to print out pictures for to generate movies.

OK Kevin, here it is: Sorry, but I don't want to give you my whole automatism for postprocessing. Without extensive explanation you won't be lucky with it, but with this example you can make your own thoughts for automatism.

! ! EXAMPLE LOOP FOR TRANSIENT POSTPROCESSING ! ! lend = loop end ! range start till end = time window for postprocessing ! incr = means postprocessing each "incr" time steps ! zaehl = just olny a loop counter ! CASE = casename ! ! For example: *set start 2160 *set end 2880 *set incr 5 *set CASE sl65-amg ! *set lend , ende - start *set lend , lend / incr *set time start incr *set zaehl 1 ! *DEFINE NOEXECUTE ! load data ! The transfer of the numeric value of the variable "time" ! as a string to the string variable "PSTI" ! In each loop the variable "time" will be increased by the ! above increment "incr" ! With brackets {} you get access to the string variable. ! *if time lt 10 then

*scopy, time , PSTI , i1 *else

*if, time, lt 100 then

*scopy, time , PSTI , i2

*else

*if, time, lt 1000 then

*scopy, time , PSTI , i3

*else

*if, time gt 999 then

*scopy, time , PSTI , i4

*endif

*endif

*endif *endif

load, {CASE}.pst_{PSTI} ! ! --------------------------------------------------- ! Here you can place what ever you want to do / plot. ! in this loop. ! ! ... ! ! ---------------------------------------------------

exit close {CASE}.pst_{PSTI} *set zaehl zaehl + 1 *END *LOOP 0 lend
