Hello,
we have been running to the same problem with the Matlab interface.
More precisely, we utilize GetFEM for assembling the stiffness and
tangent stiffness matrices using non-linear incompressible brick, but
we want to solve the system with Matlab fsolve.
Therefore, in each iteration of fsolve we need to
(a) set the actual estimation of the displacement vector (model state vector)
(b) call the assembling procedure
(c) retrive the actual assembled residual and tangent matrix
Both (b) and (c) are clear, since there are corresponding matlab interfaces,
however, there is no interface for doing (a) and we are not capable to add this
functionality to the interface by ourselves.
So, is there any other way how to do this or is it a feature that should be
implemented in future release?
Thank you
Igor
