Hello

I am trying to simulate the HgCdTe based photodetectors using Silvaco Atlas software tool. I have found the electrical and optical characteristic for the same. Now I want to simulate it for determining the lattice temperature of the device. But during this the voltage cant be sweep from -2 V to 2 v with a step of 0.1 as it shows and error that "Not A Numbers found in currents. Simulator did not converge." 

Can anyone suggest me which model and parameters should I use to simulate the same. I am using lat.temp auger srh optr models.

Regards
