Resistor definition in Piezoelectric bimorph with ANSYS workbench

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,

Phosphomonoesterase, phosphodiesterase, phosphotriesterase, and inorganic pyrophosphatase activities in forest soils in an alpine area: effect of pH on enzyme activity and extractability by R. Margesin and F. Schinner

BIOLOGY AND FERTILITY OF SOILS

Volume 18, Number 4 (1994), 320-326, DOI: 10.1007/BF00570635

Enrico Sanjust

Dear Colleague, p-nitrophenyl phosphate and bis(p-nitrophenyl) phosphate are the reagents of choice for the determinations you have requested. After enzyme action, you will check p-nitrophenol production by a mild alkaline treatment, changing p-nitrophenol into its intensely yellow anionic form (lambda max around 400 nm). Obviously a subtractive procedure should be adopted as the product arising from phosphodiesterase reaction is a substrate for the phosphatase, if present.

Ok, try.
