Running Abaqus in Matlab environment

In some cases, we need to perform a parametric study: how certain parameters affect the stress/strain/displacement at certain point or certain region in a model, or doing certain structural optimization. For such a circumstance, combining Abaqus with an additional programming language , which has an optimization capability would be unavoidable. Following shows you a snip how to perform the analysis repeatedly in Matlab.

for i = 1 : 10
istatus = dos('abq661 job=filename interactive'); % Run Abaqus,
if ~(istatus) exit; end
% Call a function to parse the necessary outcome.
% Call an optimization algorithm. See. help optim
% Call a function to modify the Abaqus input file
end
