02.4 Linear and nonlinear analysis in FEA/CAE (Increment, iteration & Convergence)

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.

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

[@simtech0598]

Thanks for such positive response. Make sure you share the knowledge with others.

[@lovindermann4814]

this is an excellent video. Thank you a lot

[@lys3521]

Thank you for this video. It helped me a lot!

[@simtech0598]

Always welcome.

[@yongjujang9264]

Thank you for explaining clearly. It will be much help for me.

[@simtech0598]

Always welcome !

[@johnkane345]

Thank you for such a detailed explanation. Please do some problems on modal analysis. Thanks again.

[@shanmukharao1683]

Really goos explanation sir, thanku very much

[@simtech0598]

Always welcome dear,
There are 4 parts. I suggest to go with all.

[@dhananjaysangamgowda8757]

really good job sir

[@simtech0598]

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.

[@CJFHXY]

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

[@simtech0598]

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.

[@sriharsha7092]

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

[@simtech0598]

Dear,
Variable load can be define by providing amplitude.

[@sriharsha7092]

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

[@simtech0598]

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.

[@kangliu6665]

But the damping factor may affect the real results, I want to know whether the affection is big

[@simtech0598]

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.

[@kangliu6665]

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