Dear guys,
I need help. I am trying to calculate the quality factor of a Double Ended Tuning Fork as you can see in the attachment. However the simulation result seems to be unphysical because the quality factor of out phase mode is smaller than in-phase and, moreover, the values seem too large with respect to experimental data What am I making wrong? Many thanks. I look forward to hearing from you .

Luca
