The Abaqus documentation, available here:
https://abaqus-docs.mit.edu/2017/English/SIMACAEMODRefMap/simamod-c-inpu...
states the following:
Certain keywords must be used in conjunction with other keywords; for example, the *ELASTIC and *DENSITY keywords must be used in conjunction with the *MATERIAL keyword. These related keywords must be grouped in a block in the input file; unrelated keywords cannot be specified within this block.
But, on an existing .inp file, how do I recognize the blocks?
I need to count them to use that number as input to the KeywordBlock object in CAE so that CAE will insert a KeywordBlock into the .inp file at the appropriate place (the appropriate place I know, but not its number).
Information about the KeywordBlock object is found here:
https://classes.engineering.wustl.edu/2009/spring/mase5513/abaqus/docs/v...
where they state:
Required Arguments. Position. An "Int" specifying the "position" of the keyword block after which the new block should be inserted.
So you see, I need to provide that number (the position), but just looking at the .inp file, I do not know how to recognize the blocks and thus I am unable to "count" them.
I have included and input file below, where I inserted the lines by trial and error (very time consuming).
I need to find the number of the *Buckle BLOCK to insert these lines:

Thank you!
