error of 'Failed to find consistent initial values'

Dear all,


I have been trying to develop heat transfer (laser pulse model), but After building model when I run the program, COMSOL showing me error ....
-----------------------------------------------------------------------------------------------------------------------------------------------------
Failed to find consistent initial values.
Failed to evaluate variable.
Variable: T, Geometry: 1, Boundary: 3
Failed to evaluate variable.
Variable: R, Defined as: ((0.58999999999999997*(T<Ttrans))+(0.65000000000000002*(T>=Ttrans)))
Failed to evaluate variable.
Variable: Gt1, Defined as: ((((1-R)*Pin)*exp((y/da)))/da)
Failed to evaluate variable.
Variable: Gt, Defined as: (((Gt1>=Gt2)*(Gt1-Gt2))*(y<=0))
Failed to evaluate variable.
Variable: mod1.ht.q0 hf1, Defined as: Gt
Failed to evaluate expression.
Expression: d((mod1.ht.q0 hf1*test(mod1.T))*(dvol),{test@0})
Last time step is not converged.
-------------------------------------------------------------------------------------------------------------------------------------------------------
I think it is not identifying Temperature 'T' !!!! al other errors are due to that only..

Please kindly help me in this matter.

I have attached .mph file of my model

Thanks in advance & Regards,
