Why do some researchers in psychometrics still use the "Little Jiffy" approach (PCA + Kaiser rule + Varimax)?

This approach is used even when exists papers where give alternatives procedures, who are more useful because focus on variance of construct, not in variance of error like the PCA.

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,
