The following terms are rather special:

*_acoustic_* terms relate to homogenization of a perforated layer w.r.t. sound
propagation and related sensitivity analysis

*_sd_* terms are "shape derivatives" (sensitivities to domain shape changes) of
corresponding terms, used in shape optimization

*_adj* terms are adjoint terms to certain terms, used also in shape optimization

*_of_* terms are objective functions and their derivatives in shape optimization

It is not trivial to use them correctly - the right context is needed.

Some care is also needed in case of:

*_th, *_eth terms are fading memory terms with convolution kernels, resulting 
from
homogenization of porous media

The rest are "usual" terms that can be used to build PDEs (dw_* terms) or 
evaluate
quantities during post-processing (de_*, d_*, dq_*).
