Restaring the analysis while using "Amplitudes"

[ashil]

I have a model consists of three dynamic steps, step1, step2 and step3.

A force, whose magnitude varies temporally, applies to a cantilever beam during these three steps. I defined an amplitude called "AMP" to prescribe this variation.

Job1 is submitted to analyze the system in step one. The type this job is "Analysis". This job is completed successfully.

Then Job2 with the type "Restart" restarts and the analysis continues during the step2. The job is completed successfully as well.

However, job3 whose type is "Restart" can not be submitted and I recieve this error message:
"AN AMPLITUDE CURVE WITH THE NAME AMP HAS BEEN DEFINED PREVIOUSLY. THIS AMPLITUDE CURVE CAN NOT BE REDEFINED".

When I look at the input files I see the amplitude "AMP" is written in the first input file but not in the second input file which both are reasonable, I think. But the amplitude is again written in the third input file and I think that makes the problem.

I do not know how to set the option in order to prevent this problem.

The problem is that the amplitude in defined a second time in the last Restart input file, a quick solution is to edit the input file (remove the *Amplitude)

Dear Stig,

Thanks for your answer; however, I have not written the input files. They were written by Abaqus and my question is that is there any options or settings that I can set in order to prevent Abaqus cae from writing the amplitude in the 3rd input file.

Once I deleted the amplitude (*Amplitude) in 3rd input file and tried to submit it again; I received an error that: "Restart of input file jobs is not currently supported." Therefor for restarting an analysis, using input file is not possible. (although CAE writes input file, you can not submit it yourself.)

Thanks again for your response and I hope you have a solution for me.

Thanks,
Ali

Hi ashil,
I can't come up with a possible solution right now, I am not at work don't have access to the CAE, trying to figure out tomorrow.
