[Getfem-users] Computing the integral over a boundary of a given Getfem variable

[David Danan]

Dear Getfem-users,

i have but a simple question.

Using Getfem, i have computed the solution of a simple contact problem (the actual geometry does not really matter).

Now, i would like to do a simple post-processing, that is, compute the integral over the contact boundary of the multiplier variable associated to the contact condition.

Using the following discussion

I think i am on a good track with asm_generic but i am not sure i am actually using it correctly as i have obtained some abnormally huge values.

Could you give me the actual _expression_ to use for such a post-processing?

Thanks in advance,

kind regards,

David Danan.
