wodan is on a distinguished road
Hello,

I try to create a large deformation solver (geometrical nonliniarity) due to the paper of Tukovic and Jasak http://powerlab.fsb.hr/ped/kturbo/Op...18-06-2007.pdf
For that I used the stressedFoam as the based solver in 1.6-ext. So, I modify the continuum mechanic equations (for large deformation) and the boundary condition in tractionDisplacement due to the paper above.
Here I am not sure of the functionality of the boundary conditions in tractionDisplacement (1.6-ext) works in the same manner as in the paper Eqn. 21.
Has anyone dealt with this kind of problem and can help here?
