Have you ever wondered whilst using SOLIDWORKS Flow Simulation - “How do I know where the minimum and maximum values are on my model?”
If so, then you're in luck as this blog will explain how to easily find these extreme values.
This week a customer asked me a simple question about Flow
Simulation:
“How do I know where the minimum
and maximum values are on my model?”
This is a good question as it can be very useful to see
exactly where the extreme values are located.
For instance, the max temperature hot spot in a heated
electronic enclosure or the max velocity point of a liquid through a valve
would be useful to know.
Let’s take the example of a racing car front wing …
We can see that there are a range of possible max and min
pressure locations, but where are the extremes?
You could right mouse button click on the Results folder and
pick ‘Min/Max Table’ but that does not show where the extremes occur – just the
numerical values.
The trick is to use the drop-down menus and navigate to …
Tools > Flow
Simulation > Results > Display, and then pick the ‘Global Min/Max’ option
This creates 2 small graphical spheres and a new Legend with
the numerical values:
·
The BLUE sphere
is the location of the MINIMUM value
The RED sphere is the
value of the MAXIMUM value
In the image below, the minimum pressure is just under the
lower wing and the max pressure is on the front / top of one of the upper
winglets.
A Cut Plot makes it clear why the Min and Max pressure are at
these locations …
I suspect very few people know that this can be done since
the setting to reveal the Global Min/Max is not enabled by default – the user
has to switch it on.
Hopefully this little tip will save you time when you are
searching for extreme result values.
