[Getfem-users] 2D nonlinear plane stress

Dear GetFEM-Users,

I use the MATLAB-Interface of GetFEM to create a program that automatically solves different models of the same problem.

The problem is three-dimensional, but can be reduced by plain stress approximation. (to reduce computing time).

I want to define a nonlinear material with the brick

                gf_model_set(model M, 'add nonlinear elasticity brick', [...])

For this nonlinear command it is specified in the description, that in 2D always plain strain is used.

So my question is: Is there a way to define a nonlinear material with the plain stress approximation? Or is it planned to install such an option in a future release?

I hope you can help me with my problem.

Best regards,

Moritz Jena
