◆ cs_compute_porosity_from_scan()

void cs_compute_porosity_from_scan ( void  )

Compute the porosity which is equal to one from a source, radiating sphericaly, and is 0 when touching points of the scan.

This function solves the following transport equation on $ \varia $:

\[ \dfrac{\partial \varia}{\partial t} + \divs \left( \varia \vect{e}_r \right) - \divs \left( \vect{e}_r \right) \varia = 0 \]

where $ \vect{e}_r = \dfrac{\vect{x} - \vect{x}_0}{\norm{\vect{x} - \vect{x}_0}} $ is the radial direction from the source $\vect{x}_0 $.

The boundary conditions on $ \varia $ is an homogeneous Neumann, and a penalisation term is impose in the cell of center $ \vect{x}_0$.

\[ \dfrac{\partial \varia}{\partial n} = 0 \textrm{everywhere} \]

Remarks:

  • a steady state is looked for.
