I am aware of other solutions to perform the same task. My current solution is to sweep the outer perimeter first and then the inner perimeter along the same path with a boolean subtraction against the first.
This updates just fine with whatever parameter changes I throw at it.

Hi there
I'm making a quick overview model of a penstock for a power plant and I'm constructing one of the bends with parametric modelling.
The bend is a 135 degree bend (path deviates to 45 degrees from horizontal) comprised from several straight pipe sections angle-cut and welded together...
With both sections combined, the entire gate is about 7 metres tall. The water pressure is at 16.5 mwc, excluding the 1.2 load factor.
The strength lies in the arced shape of the front plate.
The larger the radius of the front plate, the thinner the structure and the more "stretch" of the back...

The first two pics of tha beam was just to explain the principle. I just applied a random load to randomly sized asymmetrical beam to show the problem. It isn't affiliated with the gate itself (third pic).
The deflection on back plate of the gate is about 15 mm. The image shows a magnification...
I've got a back plate because the alternative is tension bars (ideally with joints at each end), and I'd need to have a whole lot of them, or use extremely big ones to do the job.
The plate gives me a nice big area for the stress to be absorbed into (around 50% utilization) as well as the fact...
ExcelEngineering: Interesting. I have not taken into account any second order effects. Can you explain this further?

desertfox: the full model at the bottom shows deflection.
Agent666: I've been thinking about putting a range of smaller bars on the opposite side of the stiffeners, to even it out, but I think the deflection shown here might be acceptable.

Hi there!
Given a beam/profile like this
With a force applied normally to one end and given no degrees of freedom at the other, the beam is experiencing pure tensile stress.
It should be, anyway.
In reality, what happens is that the beam bends drastically outwards and experiences bending...
Hi there
Got this gate which has
A: 17 mWC of water pressure evenly distributed on its front face.
B: Support and restriction from moving in X- and Y-directions. Restricting from rotation around X- and Y-axis.
C: Support and restriction from moving in Y-direction. Restricting from rotation...
Update:
Contacted support. Got the following answer:
This is now a known defect 88542 and will be corrected back in the next release. Thanks for reporting.
In the meantime, it seems that this is a common problem and that all my ANSYS-using coworkers have the same issue.
I also noticed that it...
Hello
After updating from Ansys 14.5 to Ansys 15, the behavior of the "Graph"-animation has changed for the worse.
While in Solution, the increase in stress and deformation works its way up to time=1, but instead of gradually working its way backward and down to time=0 again, it jumps straight...
Personally, I like using a manually set view boundary and then set the rectangle outside any geometry :P

I use the File->Export->PDF function, yes. We have it mapped to a button that automatically saves the drawing as a PDF in a PDF-folder of that specific project.
The scale is exactly the same in both views, but the orientation is slightly different.
Still, regardless of the orientation and the...
Hello all
I'm looking for someone to help me with an annoying problem I'm having with shaded views in exported PDFs of drawings.
We upgraded to NX8 this spring but there have been a few issues. One of them is this:
There is tremendous aliasing/jaggies going on in the shaded views of...

Upon placing a radius dimension on an arc, it automatically generates an extended line for that radius that extends far beyond the actual arc.
I can move the dimension around freely, but I want to remove that extended line.
When I turn off...
Scratch that, the view breaks aren't lining up perfectly either :( See the bottom diagonal break.
Do I have to use the legacy-broken-view?

Cool! This is looking good so far, but are there any tricks to making the views overlap perfectly? The views won't snap properly.
Thanks!

Hello there
We've recently upgraded from NX6 to NX8 and one of the great new features is the view break-function which I am trying to use.
I've got a piping assembly which is too long the drawing to be readable, and I'm therefore shortening the pipes with the view break-function. It gives me the...
