I READ MANY OF THE POST REGARDING THE DIFFERENCE AND AM STILL CONFUSED. MY SPECIFIC CASE IS A STATIC MIXER. IF OUTLET IS SELECTED THE GRAPHIC REPRESENTATION OF FLOW VELOCITIES AT THE OUTLET ARE SIGNIFICANTLY DIFFERENT (MORE TURBULENT) FROM THAT WHEN INLET IS SELECTED. IF THESE ARE IN FACT PROFILES OF VELOCITIES IN THE MODEL, HOW DOES THE PERSPECTIVE SHIFT CHANGE THE VELOCITY?
WHAT AM I MISSING HERE?
THANKS

Please elaborate. Or is this merrely a comment on the CAPS used by mistake?
It has to do with the length of travel the flow goes through........shorter distance less turbulence, longer distance more turbulence (in most cases, depending upon design of the items.
Keeping the caps off is a good move, thanks for that. Chris, I laughed.
Marcelo, I take it we are talking about the fact that the flow trajectories look a lot different if you pick the inlet or the outlet. If that is correct the answer is simple: the routine divides up the area to come up with starting locations for the number of trajectories sought, it them marches up or down the domain (or both) depending on what you pick. In the downstream case (ie you pick the inlet) things look a lot more orderly as most of the flow heads straight for the outlet, missing the areas where the wakes blanket the outlet. In the upstream case (you pick the outlet) then many of the vortices due to the blockages get resolved as the areas of the outlet lid where they eminate from typically are not seen by the downstream flow trajectories. Hope you get that.
much better answer than my short one, I have a fix for accidental CAP Lock too -----> http://www.convertcase.net/
Also works when you forget to use CAPS Lock on the drawing notes.
So, both are valid and simultanuous profiles? Seen from different perspectives?
Yes, just depends upon where you are looking.............it is up to you to decide what is the most relevant
The Shift Key.
