Splitting odb (one odb per step)?

[whitebalance]

Hi,
I have an static analysis with 5 steps.
The odb for the full analysis is big in size.

Is it possible to say in the input that the results from each step shall be written to seperate odb's?

Simply request the output only at specified time increments. Read more about "time points" in the documentation.

Thank you for your reply.

Using time points will only reduce the size of the odb, not create several odb's?

I need output every 0.01sec.
Say that i have 5 steps of 1 sec each, I want each second to be written to seperate odb files. Is this possible without splitting the analysis in 5?

If not possible, is it possible to tell the solver to start at at a certain time?
Say I write 5 inp files, but each analysis start at different times (0,1,2,3,4 seconds)

Ps: the magnitude of my pressures are decided by a 'total-time'-amplitude.

Why not run separate INPs? If you are going to be doing this over and over again, then you may consider going the parametric route.

Your suggestion is my last question I think?!

My model is detailed and has many loads, one for each element and a amplitude related to the load.
It is a lot of work changing the amplitudes so that the the seperate analysis start with the right pressure magnitude.

Is it possible to use the same input file 5 times, but each run starts at different times?
Something like: Abaqus job=filename.inp start_at=Step-X

Check the "restart" option.
