Trying to add LASER radiation source to a 3D model

Please login with a confirmed email address before reporting spam

Hello, i have a 3D model of the human eye, i'm trying to add a LASER source and to examine the heating distribution, i added materials for each domain such as absorption and scattering coefficients, heat capacity, mass density and conductivity as you can see here: http://i63.tinypic.com/10eepzs.jpg for gaussian beam https://en.wikipedia.org/wiki/Gaussian_beam

under global parameters i added some parameters: http://i66.tinypic.com/2128ync.png

and some analytic expressions: http://i67.tinypic.com/33kvqrq.png

and i got this error: http://i64.tinypic.com/296ejnn.png

what am i doing wrong?
