Hi everyone,
does any here know if NX Open for IronPython is able to use both the Python and C# syntaxes?
Our NX Open supplier is able to support us in C#, but we have a lot experience with Python whereas our knowledge of C# is quite limited. It would be great if we could skip the C# learning...
Hi everyone,
I am new to NX and SimCenter and I hope someone has a quick way to solve this:
in NX I created a sheetbody model of a wingbox that has the quarterchord line added. It is the blue line in the screenshot. For low fidelity optimizations I'd like to to add point loads in the...
Hi everyone,
Catia is putting some lines in a drawing, that i would like to get rid of, but can't seem to. Please see the attached screenshot.
It happens in a hatched section view of a plate washer with two chamfered holes that is also chamfered around the perimeter. I hope you can see it, but...
Hi everyone,
on our carbon spar with aluminium brackets attached, we tried to prevent galvanic corrosion by applying glass separation plies between the aluminium and carbon parts. Where glue is not sufficient, the brackets are connected to the spar by titanium bolts with titanium or stainless...
Hi everyone,
i am guessing many of you will recognize this phenomenon and maybe wrestle with it to some extent. In the company I work at we have a small team working with Catia v5 / SmarTeam. Everyone has his or her own way of doing things, which makes it hard or at least inefficient to for...
Hi everyone,
I would like to add a comment when checking in a document in SmarTeam, for example notifying that nothing major has changed, only a glue film mass dummy was added. I tried adding such a comment to the comments box in the check in window, and hoped that the comment would show up in...
Hi everyone,
for parts that have mating holes, in my company we only drill the holes when the parts have been positioned correctly w.r.t. each other. So the parts themselves do not feature that specific hole. I would like to reflect that way of working in Catia by adding an assembly hole...
Hi everyone,
can anyone explain to me why SmarTeam want to check out an older version on the fly?
I am getting this statement:
More than one revision was found. More than one revision of the same document 'PRT-0001481' was found: 'a.16, a.14'. One of these revisions 'PRT-0001481 a.14' must be...
Hi everyone,
I am having some troubles with SmarTeam and I hope that someone here has a solution for me. At my company we use SmarTeam with Catia v5. I will first state my confusion with some SmarTeam behaviours and the problems it has given us, and then a small description of how we have set...
Hi everyone,
would someone be willing to point me in the right direction for estimating residual stresses in sheetmetal plates due to cold bending? the only case i need to learn about is when a 90 degrees flange is set. relevant articles or forum threads? is this usually done using some set of...
Hi everyone,
I need some specific mechanical properties of A516 carbon steel, but as yet I am unable to find it online. Can you help me find the fatigue limit and the relation between yield strength and temperature? Are there tabulated values for this?
Thanks!

Hi everyone,
i have to do some weld strength calculation with which i don't have any experience. i am using EN1993-1-8 to guide me, but i have 2 questions:
1. in section 4.5.3.2 item 6, can anyone tell me what gamma_M2 is, that is used in the strength criterion of a fillet weld?
2. in the same...
Hi everyone,
i have been asked to perform weld calculations. I do not have any experience on this subject. Luckily, I have found EN1993-1-8 to guide me, but now I am wondering what the correlation factor beta is exactly. Is it simply the ratio of the weld filler modulus of elasticity to the...
Hi everyone,
i have been asked to perform some weld calculations. However, i am having trouble finding the relevant norms for weldcalculations on stainless steel. In particular, i am looking for values of beta.
I know beta has something to do with the ratio of material strengths, but what is...
Hi everyone,
i am still very new to FEA and continuing to ask questions. i am wondering about the following:
when simulating an almost square cabinet, lifted by two points on the diagonal, i find some very localized stress peaks. filleting sharp reentrant corners does not take away the stress...
Hi everyone,
what would the "usual" way to find the sling forces in a 4 point lift be? at the moment i am setting up a hand calculation to find them using the displacement method. it is turning out to be quite difficult and i am starting to wonder how other people have solved this.
for the...
Hi everyone,
when sizing a padeye using DNV 2.7-3 as a guideline, I come across the requirement that the von Mises equivalent stress may not exceed 85% of Re (yield strength). My problem is: how does one find the von Mises equivalent stress in a simple hand calculation (without using FEA)...
