Energy Harvesting using Piezo and MEMS Extension

Good Morning,

I am building a cantilevered beam piezo model with adjacent resistor to measure power generated.  I am using the Piezo and MEMS extension in workbench.  While using the example "Piezo fan" with the extension, I am able to run the model with success.  I am able to get a voltage response.

Now, I need to add a resistor (CIRCU94) element and measure power being generated during a harmonic response simulation.  Attached is my archived WB project.  The project shows the successful model without the resistor.  It also shows the unsuccessful model with an attempt to add the resistor.  Would you please help me figure out how to get the resistor to work?

Thank you,

Good Morning,

I am able to get the simulation to run now.  However, it is still not recognizing the CIRCU94 element and nodes.  Hum.  I will attach the latest project schematic for your assistance.

Thank you,

Phil

I figured out my error.  I just needed to use the nodes already present on the beam element for the resistor.  It seems to be working now.
