My task is to calculate a structural reliability using Monte Carlo Simulation (MCS). The sample size of MCS is 10000, therefore the abaqus is called by matlab for 10000 times. You know, it is very time-consuming. What I am interested in is the minimum displacement of the FEM model, so you can see in Line 37 of my matlab code that I only read .fil. The problem is that Line 23 (i.e. pause (0.01)) takes the majority of the time of my MCS, at least 90%! Do you know how I can do to save that much time? Can I let abaqus just create Inp_file.fil without any other useless files, in order to save time?
