Implementing previous step output as input in the using Abaqus
Implementing previous step output as input in the using Abaqus
(OP)
Dear Abaqus Users,
Help is needed please on how we can get the output displacement of some certain nodes and implement them in a formula to become forces (from each node results); and add this forces into their corresponding nodes in the following new step, for multiple steps.
Thank you for your helping answers of any approaches and they are really appreciated .
Thanks

Thank you mrgoldthorpe so much for your fast reply. I am new in using Abaqus by writing input file rather than use CAE only. If I would like to follow your approach, what is the pathway to achieve that? I already started on reading the (getting started manual, keyword edition); what other topics I should learn to be able to do this. I am sorry for asking a question might be easy but really I don’t know the right way to approach your idea. I need some steps and I will read on them to be able to write the input file.
Thank you for sharing your knowledge.

There are several User Subroutines for applying displacements and tractions. These are: DISP, DLOAD, UTRACLOAD. (However, I'm afraid isn't one for concentrated loads at nodes, the equivalent of CLOAD. Can you apply your loads via a distributed load - pressure - moonmoon?) Anyway, the principle is that you use either your calculated User Variables from say the previous load increment, or the variables you stored on a common block, to set up the loads you need.
If you still aren't sure and ask another questions, can you perhaps state more precisely what you wish to do. Other contributors may be able to help you more.
