Hi Huiliu.
Thank you for the response. I am using ANSYS 2020 and Piezo&MEMS Extension. It is compatible with the edition used since I performed an analysis for a piezoelectric actuator before. In that analysis, there was just one piezo patch. Right now, I am trying to conduct an energy harvesting analysis with 4 piezoelectric sensors, thus, obtain the voltage output and plot the voltage frequency responses for each piezoelectric sensor. For this reason, I define voltage couplings for each face of the piezoelectric sensors and apply zero voltage (ground) for the top faces. However, I receive the voltage coupling errors as mentioned above. When I just keep one voltage coupling and suppress the others, the analysis runs. I do not understand why it happens. As you said, I checked the element types from the solve file. It seems all right.
Secondly, when I run the analysis with just one voltage coupling for one piezo, I come up with the errors for plotting the voltage responses, as mentioned above. Can it be due to the polarization of the piezoelectric sensor??
Thank you in advance
