Hello,

for a model I need to define a set that includes all members of a previously defined set + counts further.

So for example I have a set i defined as the numbers from 1 to 10.

Set j is supposed to contain the numbers 1 to n+n-1.

So in this case the numbers from 1 to 19. However I. I would like to find a way to automize this step so that I can just feed in new numbers for set i while set j is calculated automatically.

Can someone help me here?

Thanks,

Graldur
