i plan to harvest electrical energy from a piezoelectric cantilever with machanical stress(and therefore strain/displacement) as the input. i am using comsol 4.2 as the design and simulation software. i build a resisitive load circuit across the piezoelectric cantilever beam (correct/incorrect).but ,i don't get the reliable answer when i opt for iteration or tolerance mode in segragated solver and when i am going for tolerance mode in segragated solver then that solver is not able to solve the problem. is there any problem regarding circuit or something else. my comsol file is attached. i am waiting for your valuable ideas,tips and suggestions..i shall be highly thankful
