    Meshing a hole with concentric Q8 - Nx 12

    Thank you both, I have resolved the problem, in the ".prt" file you can create a sketch with the divisions that you want, you can then use "divide face" or "divide body" to partition the body in the sections that you defined in the sketch.

    Meshing a hole with concentric Q8 - Nx 12

    sorry, it was not "divide body", it's "divide face"

    Meshing a hole with concentric Q8 - Nx 12

    I'm using Nx 12, my idea was to do the region as you suggested too, but I'm not finding a tool in the software that allows me to do this partition. The only one that I found is "divide body", but it only allows me to do partition across the centerline of the prt. The partition I'm trying to do...

    Meshing a hole with concentric Q8 - Nx 12

    Hello everyone, I'm learning 2D meshing for an assignment in which I have to determine de stress concentration coefficient of a part. For this I want to make a mesh that is as tidy as possible, but I'm having trouble finding how to mesh the hole so that the mesh makes a concentric pattern around...

    Exporting section info (area, inertia, etc) of elements in Nx

    That worked perfectly, I got all the data I needed, thank you

    Exporting section info (area, inertia, etc) of elements in Nx

    Hello everyone, hope you are all doing well. I'm learning how to use Nx for my first FEA college course and for our first assignment we have to design a structure that can support certain loads and make it as light as possible. The Nx result has to be validated by a MATLAB FEA code that we have...

    Stability models of rocket engines

    Just so there is a little context, in between these two months i have been taking all the end of year exams and I am now returning to this project, did not intend this question to be interpreted the same way as my previous one, instead, i'm now looking into how to start building a good...

    Stability models of rocket engines

    Hi everyone! hope you are all doing well, I was wondering where might I find solid info of how to build a mathematical model of stability in a rocket engine (given certain known parameters). Thank you all in advance!

    Modelling combustion stability on a combustion chamber

    Haha! Amazing find, will definitely keep that in mind if God decides to give me a little advice with this, thank you for the laugh :)

    Modelling combustion stability on a combustion chamber

    Thank you, you have shed some light in just how little info i was given about this project, i will ask for more data and information about the conditions of this model so i can start to work on it, because as you said, there are many instabilities to account for, and i have very little data

    Modelling combustion stability on a combustion chamber

    please do keep in mind that this is supposed to be a starting task, so maybe I'm being asked something along those lines but easier (or again, maybe someone is just playing a prank on me to see when I notice)

    Modelling combustion stability on a combustion chamber

    okay, then probably I'm misunderstanding the assignment and/or failing at translating what has been asked (or maybe they are indeed just playing a trick on me but before confronting them I will have to be sure of it), I have been told that with the measurements of the units I mentioned earlier I...

    Modelling combustion stability on a combustion chamber

    Hello, hope you are all doing well, I'm starting an internship and as my first task I have been told to analytically model the combustion stability on a combustion chamber in a spacecraft from scratch, but if I'm honest, I do not know where to begin. I do know that that some of the parameters...
