Hello, I have looked through the forum and tried looking for an answer to my question but I can't find one. Hoping you can help.

I am running an Abaqus/Explicit Dynamic analysis and looking to extract the reaction forces at a reference which has a Kinematic Coupling to another region in the model. In my .inp file I have included the line:

*FILE OUTPUT,NUMBER INTERVAL=100

*NODE FILE,NSET=GroundReactionPoint

RF

This runs just fine, and generates the appropriate .odb, .sel, and .fil files. It looks like the size of the .fil file grows as the analysis proceeds - as if data are being written.

After running the "Documentation.m" to add Fil2str to my path,

I am running the following commands in Abaqus2Matlab to attempt to extract the reaction forces:

Rec = Fil2str('test.fil');

out = Rec104(Rec);

The Rec output is a 1x771115 char. The out variable always comes back empty.

Do you have any advice? I have uploaded the .inp file in .txt format. Thank you in advance and thanks for all the work you have put into this software!
