Cow shaped solid body.
All of the surfaces due to it being an estimation.
Add in the Flow Simulation package.
Once in the Flow Simulation tab, use the Wizard to get started.
Go through the settings and decide units and starting conditions.
External flow case for air around the cow.
No internal cavities to worry about.
We are going to simulate the cow facing the wind which would be the negative x-direction.
Selecting air as our fluid.
We'd check this for part two..
Skin temperature and surface roughness.
Air velocity in negative x-direction is what we want.
A gentle breeze, like a pasture might have.
No need to simulate this large volume, so let's reduce it.
You could insert convergence goals here if desired.
Not using all of the cores since I am multitasking.
Initializing then cowmputing.
Now that it has started, you can keep an eye on the number of iterations and any warning messages.
Close out once finished.
There are many result displaying options, we'll go with a cut plot.
Choose where we want the plane to be.
We can see that there is a higher realitive pressure at the front of the cow, but it is still around 1 atm.
We don't see any abrupt flow disruptions on the underside, but what about around the udders I wonder?
The streamline view options can make it hard to see the velocity arrows, so let's change it.
Mooch easier to see.
Hm, udders don't show any vortex shedding at this low speed. Let's try Mach 1?
Not sure why the orange outline was persistent.
Much higher pressure than a gentle breeze.
Some vortices start showing up at this high velocity.
A little drafty at the rear.
Now there are some pressure differences showing up between the udders.
Air packing at front.
Thanks for watching, experiment on your own!
