Re: [Getfem-users] level set reinitialization

[Yves Renard]

Dear Wen,

The reinitialization is done there with a Galerkin method. This could work well 
but may have some boundary effects.
I think it is better to use the Galerkin caracteristic method. See for instance 
the reinitialization done
in matlab examples with convect method
interface/tests/matlab/demo_structural_optimization.m

This could of course be used also in C++ codes.

Yves.

Dear all, 

I found a very useful subroutine in delaminated_crack.cc which is used to 
reinitialize the level set back to signed distance function. It seems that 
there are 4 versions of the solver and could anyone tell me where I can find 
the reference of those methods? Thanks. 

Regards, 
Wen
