Regards the official example of "Heterojunction 1D" under Semiconductor Modula.
In Study 3, two study steps were utilized. the first one "In order to get a faster convergence, use the continuation parameter ramp to provide a good initial value to the nonlinear solver (10% of the desired value). The latter basically ramp the doping and the themionic current to their final values."
I still don't understand what this step has done. It solves the structure with different continuation parameter, then
(1) What is the output of this step for the next step?
(2) If the output is the best continuation parameter, by what criteria it is the best?
(3) If the value of the continuation parameter isn’t “1”, does it mean the doping level in the model is changed, according to the above description?
Many thanks!
