@arovinelli do you know? |

A first order approximation would be _qp_weight[_qp] times _disp_jump[_qp], Then of course you need to sum them all together. I'm not sure if there is a user object or something else already doing it for you ... Maybe @hugary1995 ? |

_normals is the local normal to the face in a side-integration, at that quadrature point. For a second or higher order element, the normal is not constant along the face, but depends on the side quadrature point. what is n_n here? normal? |

Oh ok. n_n and n_t would be the components in the normal and tangential direction function of unit vectors in the normal and tangential direction. |

I m not sure how to define the tangeant here but maybe you ll know what to pick |

OK and how can I get the normal in global coordinates |

_normal is already in global coordinates |

Hi I am using CZM on a cylindrical mesh and I want to find the total volume of the deformed cylinder (CZ deformation included) and I was wondering if there is a way to get this volume? I thought of using InternalVolume by setting a boundary surrounding the original cylinder but setting this boundary only seems to work with BoundingBoxNodeSetGenerator which doesn't work with cylinders ? Would you have any advice on how to get the full volume in this case ? Thank you
