With this update all derivatives are derived automatically with the functionality of pystencils.
Furthermore more testcases are provided.

- more time steps to get to stable solution

Use Gram-Schmidt for create_mrt_orthogonal

Closes #5

See merge request pycodegen/lbmpy!17

- "mrt" now takes relaxation rates [shear, bulk, 3rd order, 4th order..]
- deprecated "mrt3": use orthogonalized mrt now
- fixed wrong test

shear previously ignored the diagonal moments and bulk didn't exist

- orthogonalize automatically if no moments from literature are provided
- must specify whether weighted or unweighted orthogonality is desired

Fluctuating MRT: requires weighted-orthogonal method

Closes #6

See merge request pycodegen/lbmpy!15

Test for fluctuating LB, avg temperature and velocity distribution

Closes #4

See merge request pycodegen/lbmpy!16

update phase-field allen cahn

See merge request !10

Fluctuating MRT: use the correct prefactors

See merge request !11

updated the functionality and the testcases of the phase-field model conservative allen cahn

- sparse UBB boundary kernel is not written correctly
- did work up to now by chance
-> switched to channel instead of LDC test
