Voltage Result not recognized in Mechanical
I am learning to use the Coupled Fields ACT extension's tools to do piezoelectric simulation and I am testing a simple setup where a cube piezoelectric body is subject to deformation and I want to measure the voltage generated. However, when I want to solve for the voltage, the program says that the VOLTdefined result is not recognized. It shows the following message:
"Unable to create user defined result. VOLT is not a recognized result in: 59 = VOLT"
Attached is an image of my current setup. Is this a problem with mechanical not recognizing my extension? If so, how do I make sure it does?
