43C This subroutine outputs data for schlieren.
44C schlieren is eta = exp (-C ||grad(rho)||)
45C C is a constant which help user to adjust "brightness"
46C RADIOSS outputs density gradient which is recuired to output schlieren.
47C 'C' cosntant must be tuned during post-treatment then
48C is it introduced with HV result math.
