[Getfem-users] Getfem enumeration of DOFs in XFEM

[Bianca Giovanardi]

Dear Yves,

I am a PhD student at Politecnico di Milano and I am using Getfem++ for the numerical simulations involved in my thesis about crack propagation.

I have compiled and tested crack.cc. To perform some post processing computations on the displacement, I need to know how the degrees of freedom are enumerated in the vector of the enriched displacement.

I have understood that the even elements of the vector correspond to an x component and the odd ones correspond to a y component, but it is not clear to me in which order the non enriched DOFs, the Heaviside enriched DOFs and the tip enriched DOFs are set.

I hope I managed to explain myself and that you can help me.

I thank you very much for your time,

Bianca Giovanardi
