I'd like to use also this thread to expose another problem, it's about to get how [#for 1 3 1] works, it often outputs this message: dimension mismatch: from:Dim[] to:Dim[1] step:Dim[] The object works good when I try manually, but when it's done with triggers, this message come in a way that is really hard to trace, When inlets are triggered by the same flow, something sometimes comes at the outlets. Attached is an exemple of what I'm trying to expose. I do understand that there is a GRID_FLOW time as it's explained in [#finished] help file but the lack of pratical examples really slows the understanding of a "good use" of gridflow class objects. hartelijk p -- Patrice Colet
