Running Abaqus in Matlab environment

Posted in Matlab, abaqus by FEG on August 8, 2007

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

    Hello
    This is a nice blog with useful information to Abaqus. But is the blog still active? I find no newer posts.

    Hi

    I have a script setup to run an abaqus model from matlab using the dos(’abaqus job=input’) command, I then have another script which analyses the .dat file produced by the model. I’m having a problem initializing this script, basically its starting too early, (i.e. before the .dat file is created) is there a way to check the status of abaqus simulation from matlab and thus delay my second script starting until the abaqus model has been created??

    Thanks

    Yeah there is a way but could you please explain show how your script which handles the odb is?
