Hi Thomas You should perhaps add that the convergence "efficiency" (or time to converge) of segregated solver cases will often depend of the order of the variables in the different segregated steps, and that COMSOL uses (from my understanding) a rule also based on the order of appearance of the different physics. Mar 24, 2016 · In this study, a new analytical model is developed for an electrostatic Microelectromechanical System (MEMS) cantilever actuator to establish a relation between the displacement of its tip and the applied voltage. The proposed model defines the micro-cantilever ... simulations in COMSOL to estimate the induced bend loss shown in Fig. 4, which is very low in comparison with the standard fiber.
