Thanks Haider for your good suggested articles
I have got a slag sample that contains high amount of iron in it. I conducted xrd using Cu tube, on the powdered sample with very high background (because of iron efflorescence). Then to improve...

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,
