Conclusion ========== For D_ PLAN_HM modeling and 3D_HM modeling, the results agree with the analytical solution. For HM- XFEM Multi-Heaviside elements, the following features are now validated: * MODI_MODELE_XFEM * CHAR_MECA_PRES * POST_CHAM_XFEM * the calculation of elementary matrices and vectors in the case where mechanical and hydraulic Heaviside degrees of freedom were introduced in the developments of the HM coupling model.
