02.4 Linear and nonlinear analysis in FEA/CAE (Increment, iteration & Convergence)
Ғылым және технология
In this video tutorial I try to talk on increment, iteration & convergence. I also discussed why Abaqus general static step not converge for excessive large deformation/rotation & what is solution to get convergence.
In Abaqus static step it need to define time ! but as we know static analysis dose not need time. Then why it need time? A little explanation on the same.
Apart from many basics things i covered. Plz have a look, I'm sure you will get benefit of it.
I suggest to have a look on video 02.1, 02.2, 02.3 before 02.4 in playlist (Abaqus Simulia).
To know more plz check playlists.

this is an excellent video. Thank you a lot
I like your lectures because u clearly describe each and every point with their write place of use and effects on the results. Once again Thanks

Thanks for such positive response. Make sure you share the knowledge with others.
Thank you for such a detailed explanation. Please do some problems on modal analysis. Thanks again.
Thank you for this video. It helped me a lot!

Dear, I suggest you to go with all 4 video of sequence. Also go with Abaqus playlist videos.. many more conceptual videos you will find.
is it really necessary to double check the dissipation energy taken under 5% of the total cause you simply set so back in step setting process

Yes we set stabilization at 5% only. But still in 1st case stabilization is based on damping only. There one can make mistake (set high damping) to converge solution.
sir, I have created a beam and i dont know, what is the maximum load it can take, Is there any way to increase the load continuously without giving a fixed value, so that at some load the beam will fail and i will consider it as a maximum load it can take. Can you tell me the procedure

Dear, Variable load can be define by providing amplitude.

where we have to give sir, can you share a table related to amplitude

There is no fix criteria for amplitude that i can share. It can be anything as per requirement. In few videos i used variable load. Like in CEL water sloshing analysis, hysteresis loop video etc.
But the damping factor may affect the real results, I want to know whether the affection is big

Dear, To make solution stable that is one of best way. Results may vary...that you can check in post-processing as viscous damping energy.

@@simtech0598 I want to know how to measure the viscous damping energy , what the value of viscous damping energy is acceptable
