Member Function Documentation

int Nektar::StdRegions::StdPrismExp::GetMode ( int  p,
int  q,
int  r 
)
private

Compute the local mode number in the expansion for a particular tensorial combination.

Modes are numbered with the r index travelling fastest, followed by q and then p, and each q-r plane is of size (R+1-p). For example, with P=1, Q=2, R=3, the indexing inside each q-r plane (with r increasing upwards and q to the right) is:

p = 0: p = 1:

3 7 11 2 6 10 14 17 20 1 5 9 13 16 19 0 4 8 12 15 18

Note that in this element, we must have that $ P <= R $.

Note
'r' (base[2]) runs fastest in this element.

Perform backwards transformation at the quadrature points:

$ u^{\delta} (\xi_{1i}, \xi_{2j}, \xi_{3k}) = \sum_{m(pqr)} \hat u_{pqr} \phi_{pqr} (\xi_{1i}, \xi_{2j}, \xi_{3k})$

In the prism this expansion becomes:

$ u (\xi_{1i}, \xi_{2j}, \xi_{3k}) = \sum_{p=0}^{Q_x} \psi_p^a (\xi_{1i}) \lbrace { \sum_{q=0}^{Q_y} \psi_{q}^a (\xi_{2j}) \lbrace { \sum_{r=0}^{Q_z} \hat u_{pqr} \psi_{pr}^b (\xi_{3k}) \rbrace} \rbrace}. $

And sumfactorizing step of the form is as:\

$ f_{pr} (\xi_{3k}) = \sum_{r=0}^{Q_z} \hat u_{pqr} \psi_{pr}^b (\xi_{3k}),\\ g_{p} (\xi_{2j}, \xi_{3k}) = \sum_{r=0}^{Q_y} \psi_{p}^a (\xi_{2j}) f_{pr} (\xi_{3k}),\ \ u(\xi_{1i}, \xi_{2j}, \xi_{3k}) = \sum_{p=0}^{Q_x} \psi_{p}^a (\xi_{1i}) g_{p} (\xi_{2j}, \xi_{3k}). $
