[Getfem-users] question about nitsche

[Wen Jiang]

Hi Yves,

I am reading the document about the Kitsch's method for Dirichlet boundary conditions. (http://download.gna.org/getfem/html/homepage/userdoc/model_Nitsche.html)

I do not quite understand the weak form in the "Generic Nitsche's method for a Dirichlet condition" section. Could you explain the third term HG \dot Hv and the last term HD_u G[v]? Does the D_u mean the derivative of G[v]? 

Thanks,

Wen
