I was wondering if you could help me. I have recently changed across to a new version of ABAQUS (2018) and when I try to use the Abaqus2Matlab toolbox using my input file (that worked previously worked) I have come across an error.
The .fil file outputs without modal results (i.e those prefaced with 'I 41980') which will be written to the output file using Rec1980. During line 66-70 of Rec1980 out= and no results are obtained.
I am confused by this as ABAQUS completes as required and modal results are written into the correct .dat file. Could you please advise?
Thanks you in advance for your help and thank you for producing such a wonderful and user friendly toolbox.
Thank you for your advice. This has solved my issue.
Many thanks for your good words and for considering Abaqus2Matlab for your research activity, I have read some of your publications, such as the one in which you tried to numerically detect structural modification of a laboratory wind turbine blade through fuzzy FEA updating methods and I think their results are interesting.
Regarding the issue that has appeared, Abaqus results file output is not available for sim-based eigensolvers, and this is an issue not clearly reported in the documentation. For example, you could try:
in order to get the frequency results in the fil file. You could specify EIGENSOLVER=LANCZOS (default) or EIGENSOLVER=SUBSPACE in the above option, but not EIGENSOLVER=AMS, since the last is only SIM-based eigensolver. SIM=NO shows that the corresponding eigensolver will not be SIM based, and therefore it will enable output of the Abaqus analysis results to the results (*.fil) file.
The Abaqus2Matlab work team remains at your disposal for any other issue that may appear.
