2dDCB.txt

Hello,
I'm currently working on some DCB specimens for my Masterthesis and I wanted to use the VCCt Criteria forsome of the Simulations. I tried a few 2D and 3D Simulations but i don't get any Failure. So I tried to copy a 2D Model from a Youtube Video but I still dont get an Failure can anybody imagine why or do i have to activate any kind of Addin? Maby someone can have a look at my Input File and give me some Tipps.
Just note that i just copied most of the numbers from the video, so I'm not sure if they make much sense.

There are examples in the Abaqus documentation. Start with those models and data.

I already tried to work with the Abaqus examples, but the probleme is that i can't use the Inputfiles of the examples because they have a tottally diffrent structure (generated Jobs submit but don't work) than the ones generatet by my Abaqus Verison (2023). I tried to read through the Input File to find differences to my Model but i couldn't solve the Problem. Also there is no exact discription to the Cases shown in the Abaqus documentation or I'm not able to find them.

I've downloaded the first case from the referenced example and submitted it. Worked fine. You just have to submit it via command line or the A/CAE Job-Option. Do not import the model into A/CAE.

Compare the input file of the example and your input file and find the option(s) that generate the different behavior.

You might want to deactivate the Part, Instance and Assembly format in your model. Model -> Attributes

I tried to run the Input file via Job Option but it's just submitting and not running. If i do the same with a Job File generated by my abaqus version it's working perfectly fine, so there must be a difference in the Inputfiles and that is also what makes it difficult to compare the files.

It seems like you don't know how to run an input file through the Job option. Go into the Job-Module and create a new Job. Now select Source=Input File instead of Source=Model. Afterwards you can adjust the run settings. Submitting and monitoring is as known.
This is doing the same as running an input file via a command prompt and adding the settings as command parameters.
Open a command prompt in the current directory and enter:
abaqus job=inputfilename

Of course they are different. The file from the documentation was created manually in a text editor, whereas yours is created in a graphical preprocessor. But the main commands in the input file are the same (or not - in your case), since Abaqus should do the same thing. So open both input files in a text editor and look at the keywords. You can also edit and save again. Run the input file with the command prompt afterwards.
The meaning of the keywords in the input files are explained in the Keyword section of the documentation.

When you've found the keyword/option that is responsible for the issue in your model, then you can check what option in A/CAE is generating this keyword.

Thanks for the discription but i already tried it a few times with the Job option. I now found the mistake and the Input file now works after i switched to the use of multiple processors and deleted the output request for the ***** lenght. (not sure why this was a problem)

But in the end it didn't help me that much because i still don't know what's wrong with my Inputfile. I tried to compare the Inputfiles, but i couldn't find the Problem. (different syntax and Sets doesn't make it easier)
