    Drafting - Custom Symbol - odd problem

    Hi, I'm trying to create a Custom Symbol in the Drafting module. I'm doing the exact same proceedure as my collegues, and it works on their computers but not on mine. In the Define Symbol Window I can choose to place my new symbol under 1) "Custom Symbol Library / Part Symbols" or 2) "Custom...

    Advanced Simulation - Post View

    Hi, I'm comparing several versions of a design. Each version is represented in its own Post View in the Post Processing Navigator. I find it very convenient to be able to jump back and forth between the different Post Views, or even to show them side-by-side, in order to compare their...

    Advanced Simulation - Constraints

    Hi, Struggeling with "overlapping constraints" in "Advanced Simulation". Seems like NX requires that individual constraints on adjacent surfaces (shared nodes on edges) must be defined in the same coordinate system (correct?). And I am not able to choose a specific coordinate system when I...

    High strength, low Young's modulus

    Hi, I am looking for fairly strong materials with particularly high yield stress to Young's modulus ratio. Do you have any suggestions? /hpon

    Reaction force - on specific restraint

    Hi, How do I calculate the reaction force on a specific restraint? The LIS-file only prints the total reaction force. /hpon

    Ideal Gas Law - domain of validity

    Hi, I need a reliable mathematical model (P, V, T) of compressed air. The pressure ranges from 1 to 160Bar, and the temperature is bound by -30 and +70°C. Is the Ideal Gas Law "accurate" in the present case? An error of about 10-20% is probably acceptable. /hpon

    Induction sensor - installed in solid iron

    Hi, Do induction sensors work when surrounded by iron? Let's say I have a large block of iron that has a long hole (8mm in diameter) going through it. An induction sensor is placed midway through the hole, and then a solid iron cylinder (8mm in diameter) is inserted from the opposit end of...

    Analog MR-sensor

    Hi, I'm looking for an analog MR-sensor suitable for harsh conditions. Unfortunatelly, I can only find digital ones. Do you have any suggestions? Were might I find some candidates to choose from? /hpon

    Adjust FEM model (Beginner)

    Hi, I'm working through some FEM tutorials, and things are mostly going well. But unfortunatelly, the study material has left out one essential thing: Howto go back and make changes in an already executed model? The most imediate issue here is that all settings seem to be locked due to the...

    Fatigue - varying principal stress directions

    Hi, I'm looking for ways to calculate the fatigue life of a cast iron component which is subjected to several non-synchronized loads. The thing I find tricky is the fact that the directions of the principal axis varies significantly depending on the combination of active loads (I'm not even...

    Leakage through slim openings

    Hi, I'm looking for methods (preferably mathematical formulas) for estimating oil leakage through short slim openings of different shapes. I would greatly appreciate any advice that can get me closer to finding any information about this class of problems. Regards, hpon

    Lubed surfaces sticking

    Hi, What is the word for the phenomenon where two flat surfaces in contact stick to each other due to the presence of fluid in the contact? What is the physical explanation of this sticking effect? Could the effect be eliminated by minor geometry modifications of the contact surfaces? Your...

    Nonlinear Buckling

    Hi, I'm trying to run a nonlinear buckling analysis in ANSYS 12. The linear buckling analysis results are stored in ..\SYS-1\MECH\file.rst. I've duplicated the original static analysis, and placed a "Commands" object under the duplicate's Static Structural branch. The "Commands" object...

    Wind-induced load on wire

    Hi, Let's say we have a long steel wire in tension that is rigidly supported by its endpoints. The wire is slightly curved due to a transversal gravity load. Will the longitudinal load in the wire be significantly increased by a wind load? I understand that this information is very limited...

    screw mechanism analysis

    Hi, The product I'm am analyzing contains a screw mechanism. And I need to verify the structural integrity of this mechanism. How do I analyze the thread? Both static strength and fatigue properties need to be assessed. I'm sure there are hand calculation methods available, but I have not...

    Placement of a Note

    Hi, I'm trying to specify the location for the text of a Note in my drawing. Unfortunately, this task seems exceedingly difficult. I can only place the text somewhere along a horizontal line, and not a bit further down where I want it. How do I place the text where I want it? (The...

    Problem moving views

    Hi, When I move a Drawing View, several of the dimensions does not follow (even though they are selected). Therefore, I am unable to move a view without having to redo a whole bunch of editing. How do I move a Drawing View without drowning myself in extra work? Regards, hpon Regards, hpon

    Orienting Section View (drawing)

    Hi, I have created a section view (I am drawing). Everything is perfect, except the fact that the view is 180 degrees off. How do I spin it around so that it points in the same direction as the reference view? Regards, hpon Regards, hpon

    Solid shell elements

    Hi, As I understand it, a quadratic element can resolve a linear field within its boundaries, whereas a linear element only can deliver constant stress. The solid shell element SOLSH190 is an eight-node hexahedral, -and is a linear element type, right??? And should therefore deliver only...

    Create/update instance

    Hi, I'm modifying a model that was originally produced by someone else. There is one "generic" instance and one other instance. The generic instance consists of two segments: before and after machining. The other instance should represent the pre-machining segment. My assumption was that...
