ccx. It's all described in the first post. Including ccx cards. Read the procedure carefully or you can skip some important modes.
-
"¿What if the first 10 modes are all in the highest ND?" I don't think that's possible. Anyway, the first extraction would have shown all the first positions occupied by the last ND. On a second run the user would have to increase just the highest …

OMG!!. Congratulations Victor. I can't believe how fast it is.
-
Hi Victor, I would say there is a best way to extract the modes when combining Frequency + Cyclic Symmetry. Let me know what do you think? -One can request a steeped number of modes (we can talk about that later). -Sort the frequencies and take …
-
Hi JohnM and thanks for sharing your real-world experience on the subject, I really appreciate it. I'm not questioning how many modes should be reviewed, what I'm exposing is that if the designer request 10 modes (he will know why) there is no need…
-
@prop_design I have sent to you a private message.
-
I need to dig more but I suspect modes always start to fill from below. That would mean Nodal Diameter 0 is always E, Nodal Diameter 1 always T,.... I was also afraid that the shape may depend on the number of modes but that’s not the case. Given th…

I have seen a reduction in time extracting the modes up to a 400%. This morning I have wake up remembering a conversation long time ago with a friend of mine. If a non-speaking English person try to predict the next letter in a text will probably c…

Some time ago you posted a very beautiful rotor liml file. ¿Do you mind if I post some images to explain what I'm talking about?.
-
Hi @prop_design I'm not sure if what I have exposed has been understood. ¿How many modes have you request in your 7 Blade Rotor?
-
If we could find the way to cleverly steep the number of requested modes , my model could as example, be correctly computed from 5:42 min to 02:08 (extracting the right modes). This is now possible because I know a priori the occurrence of each Noda…
-
¿Would it be possible to see that model?. It's almost impossible to help without it . It could be a completely random or even a simple error. Maybe in private @hooshsim.? @prop_design? It almost seems we are talking about different models and prob…
-
I would add something else. Be sure to set up "Number of segments to output to 1".
-
i see that the modes aren't the same Hi prop_design, ¿Could you share that model?. I have recently been working on Cyclic symmetry and the agreement was very good. Regards
-
Mecway seems to be doing very well. You've made someone nervous and you already have your own haters.
-
The Center of mass was a nice check ...Additionally: -Same Density/Mass? -Same Orientation in 3D Space? I would perform a fast Modal vibration analysis to see if they both agree. Request 12 modes and pay attention also to the first six and how sma…
-
Wow!!. It worked nice and soft. Thanks for sharing.
-
. Thanks

Hi JhonM, Thanks for comment. I'm still working on this model . My goal during last weeks has been to get a model in which I can validate the Strain energy density for hyperleastic material models. I think this could be finally the right direction.…

Even more fun with Neo Hookean bouncing ball
-
What a blunder. I'm using contact thermal conductance =0 instead. Thank you Victor.
-
Hi , Energy variation or final temperature is the simplest check I can think about. I have an adiabatic system that seems to lose energy through faces in which Heat Flux has been set to 0. I was looking to find some variation in the internal energ…
-
¿Is ENER or ELSE the right variables to extract the Internal energy of a hot material? ¿Do I have to compute manually according to the instructions given in this post or has something change since August 2020.? It doesn't seem to give any result to…
-
Some fun,
-
Not sure if you are aware of this feature.?¿? Sometimes it's easier to group on the parent geometry than selecting on the mesh. You can select faces based on the Step geometry. Like in the picture. All the elements on that specific face will be link…
-
HI @Philipps ¿Could you share the exact solution for this model or provide the reference to locate it please?. I'm very interested in checking the solution. Thanks in advance

Hi, -I have also found some small jumps on areas where the mesh was irregular, or density changed. Not sure why. I' doing more test. For a uniform mesh and after refinement that difference almost disappear except close to the lib of the shell. -Re…
-
I have seen your file is called validation. I'm curious. ¿Which is the expected value?. Seems very sentitive to the BC.
-
Yep, MECWAY typically offers some workarounds. Just be careful to check you have don't duplicate elements or the stiffness would not be balanced. @Victor. Maybe this could be addressed. It happens when multiple rotation +copy are applied to b…
