- Elements are characterized by 5 aspects in Abaqus -
1. Family
2. Degrees of freedom (directly related to the element family)
3. Number of nodes
4. Formulation
5. Integration
This is online class video abaout meshing, part - 01

really awesome session sir
as same as all time your channel has the best material ,sir! thank you.
Thanks for appreciating my work.
wow, new content...glad to watch it.
Glad you enjoy it!
Thank you sir, this lecture has help me understand abaqus while also help me solve the error that i have been facing for 3 days
Most welcome dear.
Nice session sir. Kudous to your channel!!
Thanks for all your help and efforts
Always welcome
It was really helpful.Thank you very much
You are welcome!
Thank you for this video. This is genuinely one of the better videos on internet on this topic.😊
Always welcome dear.
Keep knowledge sharing.
@@simtech0598 Sir, do you also offer videos/courses on modelling damage in composite materials? I could not find them on TH-cam, at least.
Dear,
Yet I not uploaded such video. However I can guide in fracture mechanics and fracture analysis.
@@simtech0598 Thank you for your response and apologies for the delay from my side. I appreciate your kindness, I will get in touch with you at the correct time.
I am actually a 3rd year PhD student working on fracture of composites. I am well acquainted now with fracture mechanics and experimental characterization, but lack any experience with ABAQUS.
Your video was very helpful in understanding the basics, thanks again.
Very helpful video, it has made easy for me to learn from Abaqus user manual. I just have a small request that could you please make elaborative video on Solid element formulation?
May be... I'm not sure. May you can join Abaqus batches for the same. For more plz join our community on Facebook, Telegram.
Can I use C3D8RD element to simulate both linear and nonlinear soil? Because it has 8 nodes according to the lecture, 8 nodes are linear death
It's really helpful... Will u do vedio related to civil engineering steuctures
Yes dear.
I would like to give a little advice on the presentation. You point with your mouse but it's very difficult to spot where you're pointing to. You could use a bigger pointer from windows settings or use one of those programs that make a visible ring around the pointer at all times
Thanks for suggestions dear, I'll do it.
thank you for your good knowledge ... I confuse in-plane stress and plane strain..... when or what kind of condition which one I need to use?
Dear,
I suggest to read plain stree plain strain condition on Google.
In short
Plain strain - thick component..strain along thickness neglegible
Plain stress - thinn component..stress along thickness neglegible
@@simtech0598 thank you sir. I’m the same guy that gratitude in your Facebook ( from Chiang Mai University , Thailand ) thank you again sir
Sir pls take a class on contact definition and contact algorithm in abaqus
Dear, I covered those in online classes.
Hello Sir, we can use any type of combination in Abaqus. Only thing, it is not supported in CAE. In input file, we can do it.
No dear,
All elements having their limitations and validity.
Some only available for Abaqus/std
Some only for Abaqus/explicit
Most of elements available for both.
please advice me, i already downloaded all abaqus pdf files..
which book do you think its the fundamental of all?i wanna start read from it
Dear,
I don't know what pdf you are following. I simply suggest to read Abaqus Documentation, very easily available online.
sir can u explain as solid elements nodes does not have any rotational DOF(though it is assumption to simplified in mathematical point of view) then how can it deal with external moment /torque
Dear,
This assumption is very much accurate.
Consider a thin plate element of 1*1 cm with less thickness value (0.1 cm)...at same time consider a solid block with 1*1*1 cm.
Now hold from both end and try to twist them..
You will feel thin plate can be twist easily but solid block not at the same amount of force.
The force you applied to twist...now apply as tension or compression. You will find significant deformation in both solid and thin plate.
Hence no need of consider to rotational DOF for 3D elements.
@@simtech0598 well explain ,sir ....i know it ,actually it is intuitively not so hard to feel it ...but my main question was "as it has no rotational DOF so how it deal with torque?"........
i follow ur vdo , u just make essy most of complicated term underlying in FEA
Dear,
One 3D element have no rotation DOF but it can translate.
Suppose bending case for a beam of length L.. consider 1st element at fix end..with zero translation..next nearby element.. having small deformation/translation along bending direction..next to next element have more translations along z... similarly for all element.. their deformation increases gradually..and final shape looks like bend shape..
It is same as..one straight line may not capture ur curve precisely but small small N lines can capture curve precisely.
@@simtech0598 oohh,thats for why rotation is not apply for a single element instead used coupling constraint .......i got it sir ,excellent explain
Hi sir,It is really very nice explanation...thank you so much...if possible can I get this ppt???
Dear,
Every slide is shown in video..i suggest you to right in own words...it will make your understanding more clear.
Respected sir, Please help me to solve this error-
504 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.
Analysis Input File Processor exited with an error.
Thank you
Dear,
It clearly says property not assigned to 504 elements.
If you are using beam element make sure beam property.
If you are using bar element make sure the bar property.
This is a common mistake.
where is part 02?? is it coming out anytime soon??
Dear,
It was actually one lecture from Abaqus classes. 2nd part i not uploaded.
when we are considering a quadratic element having the middle one as one of the nodes, then it has 8 vertices but the number of lines connecting to these vertices is 12 instead of 16. Hence total node is 8+12 I think can you confirm sir
because you have written 16+8 is 20 which is not correct
Dear,
It is 12+8. During class i written (16+8) by mistake.
Sir, how can I draw a solid Parabolic element Strand in ABAQUS?
Dear,
By default we have only linear and quadratic elements. You need scripting for more.
I could not find part 2 of this video on the channel. is part 2 available?
No dear,
It was only class.. so only one part i recorded and uploaded.
do you know how to use frame element? it is not available in GUI
Dear,
I never listen such name.
Graphic user interface GUI there are options pls read documentation abaqus
Use the beam element, they are the same just different names. In Civil Engineering, the frame element used as an element which has also normal stiffness compare to the beam element with four degrees of freedom(for a 2D element). Somebody also calls it the Beam-Column element.
how to solve error (element missing problem)
Very strange for me. Never faced such issues. Instead, Property missing is common error when u not assign properties to element.
Hi, you should delete the explanation of Lagrangian and eulerian part from the video. They are wrongly interpreted. They are related coordinate system used. One can refer to a good book on continuum mechanics or elasticity for detailed information.
Dear,
You should follow Abaqus Documentation - Abaqus Analysis User guide - 14.1.1
The things i explained are only from Abaqus/Lsdyna Documentation.. not my own mind creation.
However, books talk in more generalized way, software documentation talk more FEA explanation point of view.
If you don't know Abaqus Documentation or if you know something else its not means you are 100% correct..You cannot suggest to remove..you should 1st discuss.
@@simtech0598 Well, I have no intention to infringe your approach or how abaqus demonstrate. I am just saying this out of my knowledge of fundamentals (I am M Tech in applied mechanics, IITD and PhD in Design, IITB ) of continuum mechanics. I can refer one extremely good book on the subject Elasticity by Martin Sadd.
You can go through video lectures on continuum mechanics by University of Michigan.
Rest, Its your content and you can keep it live as long as you wish. No issues.
Dear,
Thanks for suggestions..you may right in your context. But what i said in video is not about continuum mechanics theory, its just way to understand Eulerian and Lagrangian domain..how software treat them...this is all from Abaqus Documentation as i mentioned..u have to go through.
You can share details (book name video link etc.) here itself that if anyone interested will go through it.
Now days I'm trying to learn more about FEA once I'll little handy with it.. I'll surely go with solid and continuum mechanics.
