GetDP is still largely a "beta" software, but it may be of some interest
for the problems you describe (Gmsh is quite multipurpose, so there is
no real applicability problem). But what do you exactly mean by a
_harmonic_ temperature problem? Is it nonlinear, but treated in the
frequency domain? Or is it linear? Is it possible/suitable to consider a
time domain analysis followed by some Fourier transform?
Concerning the piezoelectric problem, a colleague of mine is testing the
current capabilities of the software. If you want to, you may share
experience with him on this topic.

Thanks a lot for the info! I did not know about the SAL project until
now, but I think I'll submit Gmsh/GetDP.
