how to link abaqus with matlab ?
You should access the abaqus results (*.fil) file via MATLAB.
In order to take your results into a fil file you should specify *FILE FORMAT, ASCII along with *EL FILE and/or *NODE FILE, etc. options in your abaqus input file (assuming that you run Abaqus/Standard).
After creating the results fil file, go to section 5.1.2 of the Abaqus Analysis User's Manual to find details about how to read the fil file. You can use this information to read this file using MATLAB.
