Hi,
I'm using DEFINE_SR_RATE to control the rate of deposition of a species onto a surface. Basically: DEFINE_SR_RATE(surf_rate,f,fthread,r,mw,yi,rr) { .... *rr = C_UDMI(c, t, SS) * k_rs * 1056 * yi[0] / mw[0]; } where C_UDMI(c, t, SS) is the fraction of surface available. What exactly is passed to the function for yi[0] ?? The manual says: "Pointer to array of mass fractions of gas species at the surface and the coverage of site species (or site fractions)" but I don't think it is the mass fraction since F_YI(f, fthread, 0) and C_YI(c, t, 0) both return the mass fraction but yi[0] returns a number greater than those. Here species[0] is the species which gets deposited and species[1] (recorded elsewhere) is the deposited species. The reaction is simply: species[0] -> species[1]. Thanks |
