APDL is just the scripting language for running ANSYS; in theory almost everything you can do in the user interface can be done through APDL. However if you're not familiar with ANSYS, this may a very challenging task. Have you looked into using the conventional user interface? What problem...

Heat transfer analysis through a multi-layered cylindrical geometry is a common topic, you might just need to look for the right key words. Here is one paper I found on the subject: https://web2.clarkson.edu/projects/subramanian/ch330/notes/Conduction%20in%20the%20Cylindrical%20Geometry.pdf...

I think your two main options are: Utilize an electric hub motor, which can be mounted in the wheel and still move with any suspension the wheel is mounted to. See here: https://en.wikipedia.org/wiki/Wheel_hub_motor#Mechanism Use a more "conventional" motor mounted centrally on the frame, and...

Why not follow the recommended guidance in the manual? Seems like 10W-30 is what you need.

The motor you've shown is way undersized for the requirements you've stated, I recommend doing some more searching to find a motor/gearbox combination which provides the torque specification of 6 N-m. You'll also need to consider expected power output and speed- you may be able to find a small...

Do you have a question? Posting to ask if anyone has experience in the area is an ineffective method for sourcing help on an internet forum.

If you want to use that motor you'll need a gearbox, the motor's torque without the gearbox is just a piece of the puzzle. The alternative would be to use a direct-drive DC brushless motor with the rated torque but that might require higher-cost components.

What kind of adhesive are you using, and how does its strength compare to that of the polycarbonate?

You could wire EDM (Electro-Discharge Machining) this feature. Wire EDM uses a very thin wire that can cut through conductive materials and should be able to do a tilted/tapered cone like this. More reading: http://www.edmmachining.com/wire_edm.htm

Nice catch and well done seeing it through to the finish line!

Why not use the equations as written with your numbers rather than try to refactor it?

This is an interesting problem, I was involved in a thread some time ago where the goal was to derive a similarly complex beam's analytical equations here: Thread: Harder beam equation The general integration method followed this form which seems to be about what you're doing as well: With...

Why doubt them? Do the science and find out!

I don't think you have a true 60 psi supply pressure, I suspect your pressure drops significantly when the flow is turned on. I would recommend using a pressure gauge to monitor the supply pressure between the valve and the hose when the valve is turned on; I'm guessing you're seeing a large...

You might be seeing a large pressure drop across the valve being used such that the apparent pressure at the start of the hose is not in fact 60 psi.
