Dear Irene,
the Newton-Raphson solution method in ATENA can be set to both Full N-R and Modified N-R. For Full N-R, use tangent stiffness matrix updated in each iteration. For Modified N-R, set the stiffnes matrix to be only updated once in each load step (if you do so, it is recommended to also switch to elastic stiffness matrix).

Hello,

In Solution Parameters, there are two solution methods to select; Newton-Raphson and Arc Length. For the Newton-Raphson, is it the combination of Full Newton-Raphson Method and Modified Newton Raphson Method ? Or only Full Newton-Raphson Method?
