A class of Crouzeix-Raviart type nonconforming finite element methods for parabolic variational inequality problem with moving grid on anisotropic meshes. (English)
[J] Hokkaido Math. J. 36, No. 4, 687-709 (2007). ISSN 0385-4035

The authors propose a class of Crouzeix-Raviart type nonconforming finite element methods for the parabolic variational inequality problem. A technique is given for obtaining the same optimal error estimates as in the classical method. It is proved that the classical regularity condition is not necessary for the finite element analysis. This paper does not contain numerical results.
