For a given finite element discretization, hidden within scratch_data, compute a right-hand-side contribution for heat-transfer and store it into the DoF-vector heat_rhs (with the corresponding index heat_dof_idx). Based on the level-set indicator function (level_set_heaviside and corresponding DoFHandler index ls_dof_idx), cells will be categorized into the different phases. We loop over all element faces that are along the phase boundary and perform a surface integral based on the quadrature rule, given by the index heat_dof_idx, to compute the laser impact. The laser parameters are laser_power and laser_position. Set zero_out to true to zero out the right-hand-side vector heat_rhs in advance. The optional arguments normal_vector and normal_dof_idx, can be used to compute the unit normal at the surface.

Note

This function should only be used, if the level-set isosurface is aligned with element faces and does not cross the cells.
