A general question on Abaqus Documentation

[Shindey]

Hi All,

I don't know whether it is appropriate to post this but I'll go ahead .

I have started reading Abaqus User's Manual, strictly on a "as and when needed".

If I have seen the topic to be read, on some videos or I have hands-on experience with, then the user's manual is very informative.
But on other hand, if I'm looking at a topic without any prior introduction, either through video or a partial hands-on experience,then the description
in user manual is very verbose and heavy.

Do other users have similar experience? If yes then what would be your advice in overcoming this problem

I don't know if it could help you but you can create an account on the dassault system website (client website or academy website depending of your profile) and you have access to libraries about all the 3ds software. If you want information and courses (with videos for IA and pdf for KW) on a specific topic (dynmaic, non linearity etc...) you can saerch it in the learning center and you'll have access to very clear presentations and "tutorials".

Regards

Hi dankoonFANTOMAS,
Nice advise.
Please send me the link to Simulia website.I have an account but I cannot find the location of videos.
Thanks

Here is the link for learning materials

http://academy.3ds.com/learning-materials/

you can select simulia-abaqus in applications

You re welcome I hope it will help you

Hi All,

I am trying to verify the compression behaviour of the concrete material that I am going to use in my CDP model. I captured the stress/strain curve from Abaqus by applying a downward (compressive) displacement in a simulated standard cube compression test. It does not match with compression behaviour which I defined in the material module. It keeps increasing as the strain increases without any degradation which seems weird. Below you could find the results.

Any help is highly appreciated.
Thanks,

3DS is asking only for a student or educator account during registration process. Unsure if the client log in still works!

Too bad because the above looks like a good source for learning Abaqus!

 

[dankoonFANTOMAS]

Hum I don't know if there is a way to find those docs on the internet or not...

They are well done and easier to understand than the manual.

Hope you'll find another way...i'll look after too

Folks,
Trying to get familiar with Abaqus. Have made some progress though but lots of ways to go before I am comfortable.

Some quick questions: Is there anything analogous to Nastran's Quick Reference Guide in Abaqus Documentation?

Since

http://academy.3ds.com/learning-materials/

is only accessible for Academic users, any good self paced tutorials, preferably free ones?

Also, in Assembly module, what is the difference between Independent & Dependent (mesh on part) instances?

I've registered on 3DS/Simulia Learning Community, where can I find the forum?

Thanks in advance.

 

[Dave442]

Dependent and independent instances are discussed in the documentation. See the previous thread:

http://www.eng-tips.com/viewthread.cfm?qid=389580

I generally just consult the Abaqus Users guide for any problems/queries. Most features are well documented.

 

[VN1981]

Thanks for pointing me out to the other thread about dependent/Independent. Was quite helpful!

I have another question. If I partition a part for meshing operations and if I realize that some of my partitions are no good. Is there anyway, I can delete the existing partitions without having to recreate the geometry from scratch? Like may be a stitching operation.

In my case, I am trying to analyze a plate with a hole (shell analysis) and I've created the geometry with in Abaqus and not imported them.

Also how does the "Steps" feature work in Abaqus? An Initial Step is generated by default and we create additional steps for load application.

I need to start consulting the Documentation as when I find time.

 

[Dave442]

If you make a mistake partitioning a part you can just delete the problematic partition. You can find all of your partitions by looking under "features" for the specific part in the model tree. Steps work just how you would imagine they work. There is an initial step where you assign initial conditions. Then you create additional steps where you define loads/constraints and required output. You can define as many steps as you want to look at multiple load cases.

You should go through the "Getting Started with Abaqus" guides in the documentation. They are brief and include several tutorials that explain this stuff.

 

[pdiculous963]

Sometimes deleting partitions will end up changing partitions created after them (Abaqus doesn't always work well updating features correctly when something made early in the model is changed). For shell models, you can try the "Remove redundant entries" command in the Geometry Edit section in the Part module. Another option is to use the "Virtual Topology" command in the Mesh module to combine faces or ignore entities. This will allow you to remove partitions without recreating your part.

 

[VN1981]

Thanks folks for the replies.

I did discover how to delete partitions without having to recreate the part. Like Dave has mentioned, I deleted them via Features in Part Model Tree.

Pdiculous963, I will have to try your suggestions.

BTW, I find meshing in Abaqus to be cumbersome currently. I cannot delete Native elements...can't split an existing quad element in two by the middle (I could only find the option of splitting a quad in to a Tria), cannot combine two Quad elements to make one. Probably there are ways to do the above which I haven't figured out yet. Currently, I am being forced to delete the mesh regions where I want more refinement and recreate them using more edge seeding etc.

Anyways, are there any good tutorials on meshing & advanced meshing, especially structured meshing using Abaqus?

Also, is there an utility to check on the value of total load applied to the model? If I have applied a uniform shell edge load of lbs/in, I need to know how much total load Abaqus is considering.

Also, is there any way to make Abaqus generate different analysis files in directory which model is saved rather than working directory?
