Hello,
i have following problem. For implementation of moving interface by use of
level set method i need to compute boundary integrals on the zero level of
level set function. What i need is determination of quadrature points which are
nearest to the zero level of level set function. I know values of level set
function from previous time step in quadrature points.
Is it possible to set this quadrature points as part of boundary, i.e. set
their, something like, boundary indicator to some number and then during
assemble procedure use standard fe_face_values procedures?
Does there exist any such functionality or should i implement it by myself?
Or generally, is it possible to set boundary indicators "dynamically",
conditionaly during assembly, or is it possible only during the setup phase?
Thank you
Marek C
