From above question, does Abaqus has the capabilty to develop time history output from a numerical model analysis ,that can be used in MATLAB program ?
Hi,
Abaqus does have the ability you need. You only have to request a Field Output or a History output for the nodes you want to evaluate. There you can also specify how many points in time should be saved. In the pre-processing stage ypou only need to save the XY-Data and write a Report file. This is a text file that can easily be imported in Matlab and further processed.
Best,
@Sascha Duczek ... Thanks a lot sir for your detail explaination , it helps me . Thank you .
As an addition to what +sascha Duczek said - you can also do this by writing a small python script. This is especially useful if you have to work on a lot of configurations. A simple example for extracting history output results is provided in the Abaqus Scripting manual.
One more thing - if you need history data, then it is more advisable to save the data you need as a History variable rather than a Field variable.
Another solution could be the User Subroutine URDFIL. Pros: It allows you to output whatever you want into a '.dat' file so as to read it from Matlab. Cons: you need FORTRAN knowledge.
+Miguel A. Ariza-Gracia - doesn't URDFIL actually write to the fil file?
Personally, I would avoid writing to the dat file - if one is working with large amounts of data, it just blows up since the *.dat file is ASCII. I prefer the odb file since it is binary and only the relevant data can then be extracted.
Arun, yes indeed. I also see your point, but in my experience I've never experienced probls while writing data (a large amount, believe me). I also used python scripts but I found it quite slow. And I also used odb, but I use to work with some clusters and moving heavy odb files is not very useful!
Cheers
Thanks you Arun Prakash and Miguel for sharing such a useful knowledge, i appreciate it very much !
A useful Matlab toolbox that can be used to link and transfer data between Abaqus and Matlab is Abaqus2Matlab, which can be downloaded from:
http://www.abaqus2matlab.com/
for free. With this toolbox, you can use in Matlab program any history or field output from a numerical model analysis performed in Abaqus.
