    Overlapping design spaces in Topology Optimization

    I am using topology optimization in NX12. I have two design spaces, consisting of two volumes which share some of the same space (see picture below). In other words, these two boxes slightly overlap. They both have constraints and load cases applied. You are seeing the resulting geometry...

    Sweep wants to twist along guide? [Solved]

    SOLVED The twist can be attenuated by selecting Alignment: By points in the Section Options. Enabling the preserve shape tick-box in Section Options solved the missing edges problem.

    Sweep wants to twist along guide? [Solved]

    I feel stupid for asking, but where do I find this command? Also, If I have square sections, is there a way to make all the sweep edges appear as edges? I only get two true edges and two 'false' edges along the sweep (sorry if poor explanation). And thank you so much for helping me!

    Sweep wants to twist along guide? [Solved]

    I am using NX12. I am experiencing an unfortunate twist in the sweep and I can not find a way to solve this. I am trying to transition from a square section to a circular section. As you can see in the images, the transition is twisted 45 degrees, as if subjected to a massive torque. How...

    (FEM) 2D mesh interprets curve incorrectly.

    Hi, Rothers. I took a look at the Prefs/meshing dialog, and enabled the Project Node to CAD, but this did nothing. Since I am using NX12, the High Resolution Polygon Bodies option has been moved to the polygon geometry tree. I assume it has previously been located in the preferences? Anyway...

    (FEM) 2D mesh interprets curve incorrectly.

    Tuw, Thank you very much for the feedback. Unfortunately, it seems I cannot apply your advice in this situation. Let me explain. The diameter of the notch is 2mm. The circumference of a whole circle is c = d*pi = 2(pi)mm. The arc in the notch is half of this =(pi)mm. That means I wil have...

    (FEM) 2D mesh interprets curve incorrectly.

    cowski, Yes, this is true. But as I mentioned, the percieved "sides" on the curve are much bigger than the element size. Sides of curve: roughly 0.1mm <-- why so large? Element size: 0.003mm Thus, there should be more sides to the circle (i.e. "higher resolution").

    Divide a curve using another curve (Sketching in NX)

    Xwheelguy Thank you! Could also use Quick Trim in that first step. The weird part is that Quick Trim sometimes leaves a point where the end of the former line was. Cowski In this case I do not intend to extrude, but to create a thin surface for latter use in a 2D mesh (FEM). The indea of...

    (FEM) 2D mesh interprets curve incorrectly.

    Im trying to mesh and simulate stress in a simple 2d example. This represents a 1x20x100mm flat piece of steel under stress. There is a stress concentration (notch) in the middle, with diameter 2mm. I have been reducing the element size gradually to find a convergence value for maximal stress...

    Divide a curve using another curve (Sketching in NX)

    UPDATE: I was able to achieve approximately what I asked about by using Divide Curve However, as soon as I have selected the defining curve, I must press enter within ≈0,1 seconds, or it will deselect automaticaly. (I assume NX is trying to prevent use of in-sketch curves as definitions in...

    Divide a curve using another curve (Sketching in NX)

    Thank you, DidierPSICAD and NutAce. Yes, both lines are in the same sketch. NX12 As mentioned, I only made this picture as a simplification of my actual work, wich has a multitude of lines and curves overlapping in the same sketch. I can not fathom why this feature doesnt exist.

    Divide a curve using another curve (Sketching in NX)

    Hello. I have tried to google this rather trivial request, but couldnt find anything. All related scenarios tend to relate to curves outside of sketches. What I wish to do is cut the green line in two, exactly at the intersection with the reference line (Red Horizontal line). [I made this...

    Auto Balloon only woks for one view?

    Thank you very much! Toost explained the solution in detail. Problem solved! [angel] Also thanks to cowski for additional information.

    Auto Balloon only woks for one view?

    I can't get NX to give me auto balloon for multiple views in different sheets. It doesn't give me any error message, the balloons simply do not appear. They worked fine in the first assembly view. Not on any of my other sheets for some reason. I was thinking I could try to add multiple parts...

    Need help exporting solid STP from NX to be used in Catia

    Never used Catia before, but have you tried exporting other file-types from NX? I would just export every available type and see if Catia can read any of them. Also, I noticed that you don't have any history on the model in NX, indicating that it wasn't made in NX. Might it be possible that...
