Hi everybody,
I´m trying to simulate a two-step bending process in Abaqus/CAE. Between the bending steps unfortunately I need to cut certain parts of my sheet. Then I want to simulate my second analysis on the basis of the results from first analysis. (stresses, hardening,..)
To do so I got my results (stresses,deformations,..) from the first analysis, imported the deformed mesh (.odb-file) to second analysis, used several CAE-Tools to create a new solid part out of the deformed mesh, and finally I´m able to cut my solid part to the shape I need for second analysis.
My question now is: How to remesh my trimmed part with the results from the first analysis? How would u solve my problem? In the following I explain how I tried to solve it myself.
To import my results from first analysis I used predefined field (inital state) and later analytical field (hardening). By using predefined field I got errors like my surfaces are not defined which is strange because my second analysis is correctly modeled (it works if no results are imported) . Is the problem that there are several elements missing to the previous mesh because I trimmed my model?
My second try was to use analytical field (mapped field - from .odb - from viewport) and use it in the predefined field function (hardening) but there I got errors in the abaqus interface.
I hope I was able to explain my problem. I really appreciate your help (also additional ways of solving the problem)
Regards,
Markus
Markus - I attached examples I made on youtube that address your questions. I had trouble implementing everything in CAE which might explain some of your problems, but this might have been because I was using 6.11 at the time.

Hi Daniel,
I´ve seen your examples, especially the second one was very helpful, thank you.
However, the second step - mapping the old results on the deformed mesh - is not working right now. My restart model starts always with stress value 0. In your tutorial you started your analysis (time 7:25) putting in your oldjob. Where exactly would you tell your model how to get the data from the previous step in the Abaqus interface?
Addtional: Is the map solution function also usable in Abaqus/Explicit? I´m trying to figure out this right now.
Thanks in advance
Markus - It appears Explicit does not support the map solution keyword, at least in the 2014 user manual. I think this is because it has other remeshing capabilities, but perhaps there is something else going on.
Predefined fields should work for the explicit case, but I don't have much experience with these. I suggest reading the user analysis guide and keyword reference guide to find if there are restrictions and how you should use the keywords.
If I remember correctly, in Standard you need the old simulation to have restart capabilities for the field you are interested in and you can use options in *map solution to specify the step and increment. See the keyword reference manual for *map solution.
Hi Daniel,
Thanks again for your help. I couldnt solve my Problem in Abaqus/Explicit, so I imported my model to Abaqus/Standard and followed your instruction with the keyword *map solution.
Right now I´m getting the same Error again and again - maybe you are familiar with it:
Error in job Mapping: The file for analysis with the rezone option was specified.
The Abaqus analysis cannot be executed
Do you know how to solve this problem?
regards
hi;
Although I am not sure about the perfect procedure you have to adopt, but there is also another way to import results from the previous analysis, you have to take a copy from your model after getting the first results and request restart and edit your attribute based on it. Otherwise use model change to deactivate the unwanted parts.
