Exporting some specified data from trn files in CFD-Pst

a.sarami · December 19, 2013, 01:13

Dear Friends,
I have about 100 transient files (.trn) resulted from a CFD simulation in CFX. I would like to write a script in session to circulate between all the trn files and gives me the AvePressure on a location at each step, for example export it to a txt file. Would you please help me on this. I almost know nothing about such coding.
Best Regards

One more thing to be noted is that the name of my trn files are not in this form, eg, 1 2 3 4 ... they are 1 4 5 7 ...
so I cannot use commands such:
!for($i=$start,$i<=$finish,$i++){}
Thanks

try smth. like

@TRNLIST= ("0", "1", "4", "5", "57")

foreach $item (@TRNLIST){
...
}

OR adjust the stepping to

!for($i=4,$i<=$finish,$i+=2){}
