Hello, 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. Kind Regards Heather

I am using Abaqus2Matlab in my research and wondering if there is a way to report nodal outputs for select groups of nodes. I am performing a Abaqus Standard study on a flexible part. I would like to extract the displacements at all nodes, as well as the reaction force at a single, specific node (a reference point which is kinematically constrained to a region of the model). I create my reference point and define an assembly nodal set RP_set which contains it. I understand that if I put the following in the .inp file, I will write out the displacements and reaction forces for all nodes: *FILE FORMAT, ASCII *NODE FILE U, RF Is it possible to write out the displacements for all nodes, but the reaction forces for the reference point in RP_set only? Something like the following: *FILE FORMAT, ASCII *NODE FILE U *NODE FILE, NSET = RP_set RF Thanks! Appreciate all the work you have put into this package and the community on this website.

I use Abaqus2Matlab to determine material parameters with an inverse analysis. I use the following optimization procedure: - Initialization of the variable x = [Eta1, E2, Eta2] - Creation of the subroutine with the variable x used in the Abaqus job - Abaqus job run - Extraction of the node displacements needed and the time increment - Comparison with the experimental data. Every parts of the code works, but the value of the parameter x is not changing during the optimization procedure. Do you have an explication to this problem? Thanks. I am attaching my Matlab files:
