sailfish.solvers.cbdiso_2d.Patch

class sailfish.solvers.cbdiso_2d.Patch(time, primitive, mesh, index_range, physics, options, buffer_outer_radius, buffer_surface_density, lib, xp, execution_context)

Bases: object

Holds the array buffer state for the solution on a subset of the solution domain.

__init__(time, primitive, mesh, index_range, physics, options, buffer_outer_radius, buffer_surface_density, lib, xp, execution_context)

Methods

__init__(time, primitive, mesh, index_range, ...)
advance_rk(rk_param, dt)	Pass required parameters for time evolution of the setup.
maximum_wavespeed()	Return the maximum wavespeed over a given patch.
new_iteration()
point_mass_source_term(which_mass[, ...])	Return an array of the rates of conserved quantities, resulting from the application of gravitational and/or accretion source terms due to point masses.
recompute_conserved()	Convert the most recent primitive array to conserved.

Attributes

cell_center_coordinate_arrays	Return two 2d arrays, one with the cell-center X coordinates, and the other with the cell-center Y coordinates.
primitive

advance_rk(rk_param, dt)

Pass required parameters for time evolution of the setup.

This function calls the C-module function responsible for performing time evolution using a RK algorithm to update the parameters of the setup.

property cell_center_coordinate_arrays

Return two 2d arrays, one with the cell-center X coordinates, and the other with the cell-center Y coordinates. The arrays are either numpy or cupy arrays, allocated for the device this patch is assigned to.

maximum_wavespeed()

Return the maximum wavespeed over a given patch.

point_mass_source_term(which_mass, gravity=False, accretion=False)

Return an array of the rates of conserved quantities, resulting from the application of gravitational and/or accretion source terms due to point masses.

recompute_conserved()

Convert the most recent primitive array to conserved.
