Abaqus + Matlab iterative solver

[Frankie183]

hi!

I'm trying to integrate abaqus with matlab, in such a way that I want to know the displacement for a given force on an beam structure. In matlab, the solver looks generally like this:

While error >predetermined error
1. F = F + increment
2. Input the Force in the INP file of abaqus
3. Load the displacement from abaqus
4. error = new_displacement - predetermined displacement
end

Now I don't know an efficient way to change the .INP file for the submission of the simulation, any recommendations?

Check the Abaqus2Matlab program. You may also use Isight by Dassault Systemes.
