Detailed Description

Robin eigenproblem on the disc: -lap c = mu c, D dc/dn + k c = 0 (n out of the fluid), D=R=1.
Exact: sqrt(mu) = x with x J1(x) = Bi J0(x).  Variants:
  RF   : flux form - aperture FV, kappa mass, all kappa>0 cells, wall flux A_w c/(d_centroid + 1/k)
  RFc  : same, d measured from the cell CENTRE (sdf), clamped >= 0.05 h
  RG   : linear ghost on centre-fluid cells, c_Gamma eliminated through the normal Robin relation
         (diag += k|n_a| / (h (1+k d_n)) per crossing link; k->0 = staircase Neumann)
