I'd prefer your videos without any background music, to be honest. But I like the information you give. If I had these videos some years ago, things would have went a lot different. Keep it up.
During recording there is background noise. I don't want that viewers disturb by background noise, so i need to add background music to supress background noise. Thanks for your response. Hope now you will get benefit of video.
I have gone through previous videos in this playlist. Background music is OK there. But for this video it's little difficult to concentrate because of music. Anyway, we understand your issue. Keep rocking. All the videos are simply superb for one who wants to learn. People won't get such info for free. I appreciate and thanks to you.
Thanks Swapnil for appreciation. Anyways, i decided to remove or make background music very less. New video of Abaqus Simulia playlist don't have any background music.
Dear, In few videos background music is High by fault. However i stopped adding background music. I suggest not to use earphone. Only in earphone background music is high.
Greetings, I only have a doubt about the example of the minute more or less 6:36, it is not clear to me why we do not calculate the frequencies directly with the force 2224 N but we must necessarily create other increases in load or time (I did not even understand well the link between time increase and load increase) thank you for your help.
Dear, When we apply load, shape of input model changes. And we want to find frequencies of stretched bar not the original bar. That's why 1st we stretched object than applied frequency step.
@@simtech0598 Thanks for the reply, but I just wanted to understand what is the difference between applying the 2224 N load right away and finding the frequencies right away, instead of going from 224 to 2224N (then making 10 increments) and then having to apply the step and find the frequencies? in a nutshell, why is it necessary to divide the GSS analysis into 10 increments? improves computational efficiency? I'm not understanding.
Dear, Governing equations may not converge for larger amount of force and time increment due to higher value of residue. So in FEA we always divide problem into small time increments. I suggest you to go through Abaqus documentation for more details.
@@simtech0598 Hi sir, sorry but I don't understand, because in each frequency of each mode of vibrating I have that the maximum magnitude is 7.12 and not 1, how you calculate the amplitude with a force to see a comparison with the analytic form where it comes out the same frequencies but with a shape size equal to 1?
@@simonelasciafare3080 @SimTech05 Greetings, I asked myself the same question, because I don't understand what amplitude Abaqus uses to multiply it to my wave equation in closed form on my code string, to get the same answer as Abaqus but on Matlab. because on Matlab the lowering is 1 while on Abaqus the maximum deformation for each modal is equal to 7.12. Thank you
I run linear Perturbation Step in Abaqus for my model and for my first 2 modes the natural frequency was zero and for 3rd to 6th steps the values were 107, 655 and 1010 ...Why could be the reason for the first 2 modes to get zero values ???
Dear, If your assembly have any rigid part...for that natural frequency may be zero. But for deformable part natural frequency cannot be zero. Two mode shape may be same if model is symmetric along these 2 directions.
Dear, As per my knowledge it is not possible to plot them both at a time. But as you try to plot model analysis results, the previous step deformation will be there...

Brother, music is too high in video. Its difficult to concentrate on audio.

Thanks a lot, I really appreciate you, Sir, for such a great job of helping others. Continue it
Good to know a positive feedback. Keep knowledge sharing.

We can present the result of static step and the mode0 of frquency step in the same contour results?

Sir can you help me provide me software link to download and learn from your tutorials.
Very informative tutorials.
