Dear Mr. Kjelberg,

in my simulation of piezo disk I get (after subdomain integration):

Electric Power Dissipation 28W
Structural Power Dissipation -16.9W
Electro-Mechanical Power Dissipation 11.1W

i.e. equation Qe_smpaxi+Qs_smpaxi=Qes_smpaxi is correct.
But what is physical meaning of negative Structural Power Dissipation?
Second question, I suppose the heating power is Qes_smpaxi. Is it correct?

Regards,
Vladimir Ravitch
