- test_case_widget:
widget of the test case (see test_case.py).
- lb_scheme_widget:
widget of the lattice Boltzmann scheme (see lb_scheme.py).
This widget is composed by a menu where you can modify the discretization parameters,
the generator used to build the numerical kernel into pylbm and the desired outputs for
post treatment.
This widget is also composed by a main widget where the simulation can be started and
a plot is given in real time for the available fields. A period can be modified to control
the plot frequency and a snapshot of the current figure can be made.
