The optimum length for FRP shear strengthening of RC beams subject to uniform distributed load. Is it logic ?

I`m conducting a parametric study using FE abaqus on RC beam shear strengthened with externally side-bonded CFRP. The optimum length which i get is 0.36L, where L is the beam length. Is this...

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,
