//!  Anisotropic pressure drop (along a unit vector v and in the plane orthogonal to this vector)
/**
   Corresponds to the sum of a pressure drop of intensity lambda in
   the direction of v, and a pressure drop of intensity
   lambda_ortho for every direction orthogonal to v.
 
   Or equivalently, the sum of an isotropic pressure drop of
   intensity lambda_ortho and a directional pressure drop
   of vector v and intensity lambda - lambda_ortho. This is how
   the computation is coded.
 
   du/dt =
   - lambda_ortho(Re,x,y,z,t) * u * ||u|| / 2 Dh
   - (lambda(Re,x,y,z,t)-lambda_ortho(Re,x,y,z,t))
   * u.v * v * ||u|| / 2 Dh ||v||^2
