Re: [Getfem-users] crack tip and orientation

[Yves Renard]

Dear Wen,

The global_function_on_level_set represents indeed a function defiened a priori on the whole mesh and on local coordinates (x,y) defined by the two level sets representing a crack. In particular, this suppose that the two level-sets define correct coordinates i.e. being close to signed distances.

And concerning the function get_crack_tip_and_orientation in getfem_crack_sif.h, indeed should find the intersection of the two level-sets (may be indicating a candidate zone), but it has not been implemented

Dear all,

I am currently implementing a 2d crack propagation code and not very clear about some functions.

1) global_function_on_level_set

what does this function do? Is this global function defined on a local coordinates represented by a  level set?

2) get_crack_tip_and_orientation

I understand that this function has not been implemented yet. could you give me any suggestions on how to implement it in getfem++?

Thanks in advance.

Regards,
Wen
