Creating a new variable

[Cansand]

Hello
I am willing to use the scripting interface in ABAQUS for post processing the results and getting an appropriate output variable. The new variable I am willing to obtain is the ratio SF=[Mises stress at a point (resisting) / Maximum Mises stress (operating) at that point]. I never used Python or scripting interface before. Can anybody guide my systematically (steps) on how can I do that. Any body did that before..

I really appreciate your help

Thank you

Step 1. Be sure you have access to Abaqus Documentation and Python Documentation
Step 2. Start reading the ABAQUS Scripting User's Manual and practice on the tutorial code.
Step 3. If some of the commands related to Python are not clear you can find tons of Documentation at

http://www.python.org

Step 4. If some commands related to ABAQUS Scripting Interface are not clear you can look them up in ABAQUS Scripting Reference Manual

You don't need to use scripting necessarily to do this. You can create a new field from exsiting ones.

In the Visualization module: Tools - Create Field Output - From Fields...

Make sure you have chosen the appropriate field outputs before you run the analysis so you have them available to you for this postprocessing operation.

the field variable I am asking for cannot be created in the way you are talking about. can it..?

If you want a output of the following:

Output noteset-1 (New) =
Output noteset-1 (Step X)/ Output noteset-1 (Step Y)

Then brep method should work.
