Scilab

I have managed to adjust a material property to get the best fit to the experimental response using fminsearch in MATLAB, but I lost access to free MATLAB so I have to use something else. I like Scilab, it works for everything I did with MATLAB except this. 

Scilab throughs and 'invalid handle' error when executing:

  dos('abaqus cae -nogui response.py','-echo');

at the line inside response.py:

  Job.submit(consistencyChecking=OFF)
