Hallo Badhani,

 Usuallay there are two functions which could be used:

-OP=MOD (modifing the step)

´-OP´=NEW (creating new step whithout the assumption of the first)

i advice you to work also with restart file. check the analysis manual in abaqus

It is not clear what you wanted. But what I get from your question is you want to edit the inp file and add more than 1 steps by editing the inp file. So, to do that you can just add *STEP......*END STEP, and start a new step by again *STEP....*END STEP. Here is an example:

*STEP

**Add boundary, load, and necessary things

....

*END STEP

** 2nd step will start here

*STEP

** Add boundary,load an necessary things for this step

...

*END STEP

.........

*STEP

...

*END STEP

Hope It helps!!

Thanks for your valuable replies, Actually i want to depict the construction phase of DAM for that i am using the Model change feature depicting each lift activation.So I have to add around 216 steps for representing 216 lifts.Doing it manually will be tedious task.I have not yet submitted my job so its inp is not yet generated.So i finally did that by recording a single step and then edit it and applying loop to it and thereafter running the script.

Dear @Badhani

Can you kindly explain.. little bit in detail how you have done it? It will be very helpful for me..

This is easy but you'll need Indian high school level (7-8th grade) programming skills.

1st save the CAE file, next create one step in abaqus. Save the CAE file again. open the jnl file.

!!!DO NOT MODIFY THE jnl FILE!!!!!!,

go to the end of the jnl file, you'll see the python script for creating the step (sandwiched between two lines of python code that show your successive saves). Just copy the script and paste it in MatLab or any other progam writer like TurboC.. even a python eidtor like PYcharm will work. I like Matlab. ;)

create a for loop with fprintf statements containing the python script. obviously you'll have to iterate some numbers like for i=1, step =1, for i=2, step=2 ,etc

be careful of syntax and indentation.

Once your script is generated copy it and paste it in the command line interface (CLI) of Abaqus.

have fun!
