write an input file

write an input file

write an input file

(OP)
is there some good example  available online??

I have found someone but I ask also to you..thanx

RE: write an input file

a good starting point is to use the CAE to create the input file for you. then you can replace the node and element define method in the input file with parameter option if the geometry is sample.

RE: write an input file

Use ABAQUS Documentation->
Getting Started with ABAQUS/Standard: Keywords Version   
->2.2 Format of the input file

RE: write an input file

(OP)
thanx for the reply

yes I try to use Abaqus Manual keywords version

but some file available online??

an other point is look at the input file after you have generated it with cae. But when u writ directly probably is more "compact" (short)..is true?

RE: write an input file

i have a problem in specification of mass scaling factor for a dynamic problem.

RE: write an input file

The big advantage I can see from writing the input file directly is
a)    You can add parameter in it so it is re-useable with different dimensions.
b)    The node numbers can be controllable.
c)    When you need a lot of input that requires cut and paste from Excel

Where how compact is the input file does not mater as it will not effect the performance of the analysis.

There is some example in the ABAQIS example problem manual (HTML version), that would be a good starting point.

However, I would suggest that you start to build your model with CAE first, then start replacing the input file with your own text. I have 2 recommendations.

1)    Add “cae_no_parts_input_file = ON” in the abaqus_v6.env file to make the input file without part. Having part in your model make it harder for a beginner.
2)    Change one thing at a time as 99.99% chance you will make a mistake and it will be a pain that you need to check the whole input file for a typo.

Hope this help
