To perform a similar analysis, consider the following hints and recommendations:
For piezoelectric materials, ensure that the polarization direction (defined by the element coordinate system) is correct.
The IEEE standards list the coefficients based on (x, y, z, yz, xz, xy) ordering, while Mechanical APDL input requires (x, y, z, xy, yz, xz) ordering. For more information, see Piezoelectric Matrix in the Coupled-Field Analysis Guide.
