How to create a statistical RMS graph
Posted: Thu Nov 29, 2018 12:25 pm
Hi everyone
I need the root mean square of a pressure on a line graph, so I need to create a statistical graph.
1) there's no automatic way to compute that right? (for average, std, maximum we only need to go to Window->create statistical graph)
2) I thought to proceed in this way:
a)create result -> Result1: pressure Operator: * Result2: pressure New name=pressure^2 select all step box
b)create statistical graph -> all step statistical operation: average of: pressure^2
That should create the RMS....
My doubt is on create result, because Gid forces you to choose a time step for result1 and for result2 even if you select "all step box".
The question is: Is it only a bug ? Everything works fine in any case?
