Hello
I want to simulate a 3D GaAs PIN photodiode according to the application gallery guide (GaAs OIN Photodiode).
In my simulation (please see the attachment), except for the analytic doping profile, I totally built the PIN photodiode in 3D according to the guiding PDF. But it cannot compute, it always shows some information as follow
Undefined value found. - Detail: Undefined value found in the equation residual vector. There are 50 degrees of freedom giving NaN/Inf in the vector for the variable comp1.Ne. There are 19 degrees of freedom giving NaN/Inf in the vector for the variable comp1.Ph.
And I noticed the difference between the 2D model and 3D model when it computing, there are two segregated solvers appare, but the solvers are not converged.
I have simulated both 2D and 3D structures in RF model, but there is no difference in setting. What is the difference between 2D and 3D models in Semiconductor-Electromagnetic Waves Coupling? What should be set (changed) in my simulation (the attached file)?
Thanks in advance for your help and answers.
