Dear Yves,
When I create a new level set on a getfem_mesh, I have to also set
values of
the level set function by setting
ls.values( )[i] = ..
for all the nodes of my original mesh, that I want to cut by the level set.
I browsed through the examples, located in getfem instalation, and I see that
all of them have quite simple procedure of doing this. Namelly, in every
example this procedure strongly depends on the geometry of the problem and I
didn't see some generic way of doing this. This is particularly a problem if
your level set (geometry of your interface) is quite arbitrary, as in my
case.
Is there a way to set those values in some generic way?
By, say, computing a signed distance between your interface (possibly defined
as a getfem::mesh itself) and the nodes where you have to define the value of
your level set?
Thank you in advance,
Andriy
