nc_dqcdzeta
Produces a list of derivative matrix
\[\frac{\partial(\mathcal{A}\boldsymbol{\Gamma}_0)}{\partial\boldsymbol{\zeta}}\]
where \(\mathcal{A}\) is the aerodynamic influence coefficient matrix at the bound surfaces collocation point, assuming constant panel norm.
Each list is such that:
the
ii
-th element is associated to theii
-th bound surface collocation point, and will contain a sub-list such that:
the
j
-th element of the sub-list is thedAIC_dzeta
matrices w.r.t. thezeta
d.o.f. of thej
-th bound surface.
Hence, DAIC*[ii][jj]
will have size K_ii x Kzeta_jj
If Merge
is True
, the derivatives due to collocation points movement are added
to Dvert
to minimise storage space.
To do:
Dcoll is highly sparse, exploit?
