Thanks a lot for your help @AbrahamYezioro. I will check these and see which works best. I’m a bit worried about memory now. Would it be faster and less memory consuming if I change the idf file name iteratively? so that I get an idf file for each iteration and that should have the results I need. I was trying something like the image below but wasn’t sure how to link that to colibri so that slider with file name corresponds to the combination of design elements in colibri iterator. any ideas?
